1 00:00:01,140 --> 00:00:07,140 Hello, everyone, and welcome to the Oxford Martin School. My name's Charles Comfrey, I'm the director. 2 00:00:07,140 --> 00:00:14,340 Before welcoming our speaker this evening, I also welcome Melanie Whelan, the chief executive of BBC. 3 00:00:14,340 --> 00:00:21,720 And I can go over there and see CEO of Rotherham said research is very welcome at the school. 4 00:00:21,720 --> 00:00:32,610 It's an enormous pleasure to welcome utterly, utterly later to the school autoline as a hugely distinguished plant molecular biologist. 5 00:00:32,610 --> 00:00:35,430 She's director of the Sainsbury's lab at the University of Cambridge. 6 00:00:35,430 --> 00:00:43,500 And I think is that the picture from your window that might have been utterly off office looks at over the botanic garden. 7 00:00:43,500 --> 00:00:49,860 She's professor of plant development. She's active in a huge number of other things in the UK. 8 00:00:49,860 --> 00:00:55,140 She's a fellow of the Royal Society, and she chairs the Royal Society's Policy Expert Advisory Committee. 9 00:00:55,140 --> 00:01:01,350 She's a member of the Council for Science and Technology that directly advises the prime minister on those issues, 10 00:01:01,350 --> 00:01:06,280 and as I said, she was made a dame in 2017. I think you're very welcome here. 11 00:01:06,280 --> 00:01:18,830 Please come and give your talk. So thank you for the invitation, it's really a pleasure to be here. 12 00:01:18,830 --> 00:01:26,150 I've been sort of going over in various ways what I wanted to talk about. 13 00:01:26,150 --> 00:01:29,840 I was originally going to give a sort of very general implant, wonderful talk, 14 00:01:29,840 --> 00:01:38,990 and then decided that the opportunity was actually too good to miss with this kind of mixed audience instead to talk about about GM at some level. 15 00:01:38,990 --> 00:01:48,380 I very rarely talk about GM in that defined way, and you'll see as I go through why I very rarely talk about GM in that defined way. 16 00:01:48,380 --> 00:01:57,380 But I think now is actually an extraordinarily important moment to start thinking about it again in a in a different way. 17 00:01:57,380 --> 00:02:10,340 OK, so that's the preamble. So as I understand it, this is the seminar as part of a series in the kind of general kind of food futures books. 18 00:02:10,340 --> 00:02:20,990 And I think one of the things that is very clear about the future of food is there is a very broadly held consensus about what's needed. 19 00:02:20,990 --> 00:02:27,590 I wrote this slide and then I found something almost exactly the same on the Martin School website. 20 00:02:27,590 --> 00:02:35,030 Everybody pretty much agrees that what we need is this, you know, reliable, resilient supply of food that is safe, 21 00:02:35,030 --> 00:02:41,510 obviously, and nutritious and affordable, and it's produced in a way that's environmentally sustainable. 22 00:02:41,510 --> 00:02:50,160 And if there are any risks and certainly when there are benefits, they should be equitably shared in an appropriate way across the food chain. 23 00:02:50,160 --> 00:02:57,080 So very clear, everybody's. Pretty much can sign up to this thing. 24 00:02:57,080 --> 00:03:06,200 And yet we are in a situation where many of the the issues that surround is common goals are highly contentious. 25 00:03:06,200 --> 00:03:15,230 So how you go about achieving this is very unclear. And my area, which is plant genetics, is particularly contentious. 26 00:03:15,230 --> 00:03:20,480 So what are the contributions for plant genetics to delivering these goals? 27 00:03:20,480 --> 00:03:28,850 And they are particularly contentious in the context of of genetically modified crops and that the quality of the debate around GM. 28 00:03:28,850 --> 00:03:36,500 In my opinion, is very poor and and highly polarised and not helpful. 29 00:03:36,500 --> 00:03:47,660 And having worked in this space more or less through the whole period of time when this debate has been going on from its inception forward, 30 00:03:47,660 --> 00:03:53,450 it's been interesting watching the discussion about the debate. 31 00:03:53,450 --> 00:04:01,970 So generally speaking, I would say there are two hypotheses for why it is that GM is so controversial. 32 00:04:01,970 --> 00:04:11,420 And one of them, which is a kind of classic deficit model, has been around for a long time right from the beginning and refuses to go away, 33 00:04:11,420 --> 00:04:16,430 despite the incredibly powerful evidence that it really has nothing to do with it. 34 00:04:16,430 --> 00:04:22,100 So there are still many people of the view that GM is perceived as dangerous just because people don't understand what it is. 35 00:04:22,100 --> 00:04:29,270 And if only we explained it to people and these people, whoever they may be, then everything will be fine. 36 00:04:29,270 --> 00:04:35,780 It's there, and as I say, it refuses to go away as an explanation, despite the very good evidence that it's not what's going on. 37 00:04:35,780 --> 00:04:41,570 There is much better evidence that what's going on, you can frame it in various different ways. 38 00:04:41,570 --> 00:04:45,620 I like to frame it in the context of social identity theory. 39 00:04:45,620 --> 00:04:55,640 So GM has become a kind of poster child for nasty, profit driven agriculture and nasty profit driven agriculture has associated with it a variety 40 00:04:55,640 --> 00:05:01,820 of characteristics that go completely against those goals that everybody agrees or could go. 41 00:05:01,820 --> 00:05:06,500 So it's supposed to be a poor in the context of food safety. 42 00:05:06,500 --> 00:05:12,770 It's supposed to be very poor in the context of quality across the food supply chain, 43 00:05:12,770 --> 00:05:17,420 and it's supposed to be very poor in the context of its environmental sustainability. 44 00:05:17,420 --> 00:05:26,930 And unfortunately for those of us working in in science, science has become associated with that whole package. 45 00:05:26,930 --> 00:05:30,740 Profit driven nasty agriculture is science driven, 46 00:05:30,740 --> 00:05:37,250 whereas the nice sort of agriculture is all about nature and the science like this stuff is terribly kind 47 00:05:37,250 --> 00:05:45,170 of reductionist and and unsophisticated in a way where the nature stuff is all lovely and holistic. 48 00:05:45,170 --> 00:05:53,810 And you see this very straightforwardly in supermarkets. If you label your food as natural, however incredibly unhealthy it might be. 49 00:05:53,810 --> 00:05:57,620 If it's labelled natural, it will sell and it's lovely. 50 00:05:57,620 --> 00:06:08,210 And then this is I'm very much like this advert for a particular sort of sauce, but it is very direct. 51 00:06:08,210 --> 00:06:14,960 Scientists should not be allowed to make food. I don't know if you can read this thing here, but it says if, if so, if you let scientists loose on, 52 00:06:14,960 --> 00:06:20,260 this will only be about efficiency and all the rest of it, and it will taste horrible. 53 00:06:20,260 --> 00:06:26,840 And OK, so this is obviously slightly jokey advert, but at the same time, it's it's an advert. 54 00:06:26,840 --> 00:06:33,140 It's selling you food and it says science has nothing to do with this food because science would not create high quality food. 55 00:06:33,140 --> 00:06:45,410 And then, you know, in this nature science dichotomy that the one is the loudest people is His Royal Highness the Prince of Wales. 56 00:06:45,410 --> 00:06:56,880 And these are quotes from a recent lecture he gave in 2011, which absolutely highlight this tension that is perceived to be going on. 57 00:06:56,880 --> 00:07:03,890 We're told that science has all the answers that the depiction of science is kind of arrogant and and reductionist. 58 00:07:03,890 --> 00:07:11,120 So they say when actually we should be thinking about nature, which is this much more lovely, holistic, complex, beautiful thing. 59 00:07:11,120 --> 00:07:17,510 And we need to restore the balance between the reason of instinctive wisdom and this the 60 00:07:17,510 --> 00:07:23,060 rational insights of scientific analysis as those two things were completely separate. 61 00:07:23,060 --> 00:07:29,990 And you know, we need to show greater respect for the genius of nature's designs on this stuff. 62 00:07:29,990 --> 00:07:37,490 As I say, you know, Prince Charles doesn't mean it's unusual that people go, Yes, we agree with Prince Charles. 63 00:07:37,490 --> 00:07:43,010 But nonetheless, this this kind of narrative is very common in the entire debate, 64 00:07:43,010 --> 00:07:46,340 and this is where this kind of idea of social identity comes into play. 65 00:07:46,340 --> 00:07:54,500 So social identity theory was developed primarily by Henry TouchFLO, and it's about. 66 00:07:54,500 --> 00:08:02,360 A very deeply held psychological mechanism for dealing with insecurity and feel of fear of the unknown and what you do is 67 00:08:02,360 --> 00:08:08,940 you get together in an enquiry and you all tell each other how correct you are and how wonderful and support each other. 68 00:08:08,940 --> 00:08:15,770 That's that's not too bad. But unfortunately, part of the whole thing requires that to be an outgroup. 69 00:08:15,770 --> 00:08:21,080 So part of the bonding of the in-group is that we don't like those people over there who disagree with us. 70 00:08:21,080 --> 00:08:32,480 And as I say, lots of I'm very impressive experiments arbitrarily dividing people into groups who within hours will adopt in-group outgroup idea. 71 00:08:32,480 --> 00:08:34,040 They support the people in their group. 72 00:08:34,040 --> 00:08:40,530 They don't like the people in that group, even when you've given those groups completely arbitrary things that they like and don't like. 73 00:08:40,530 --> 00:08:49,490 So the basis of these experiments. So you wind up with in-group favouritism and outgroup derogation and within Greek social influence, 74 00:08:49,490 --> 00:08:56,600 which homogenised is both the the the opinions of the in-group, but also the opinions of the outgroup. 75 00:08:56,600 --> 00:09:05,000 And then you have polarisation and that you can see incredibly clearly in the context of this science nature and 76 00:09:05,000 --> 00:09:12,860 actually more broadly in the concept of science as a activity done by strange boffins in labs versus people, 77 00:09:12,860 --> 00:09:17,810 and particularly if those scientists are kind of corporate and therefore profit driven, 78 00:09:17,810 --> 00:09:24,470 you wind up with the in-group who these scientists who are, you know, feel embattled in their labs. 79 00:09:24,470 --> 00:09:30,890 You think they're doing a good job trying to see the world pitted against the outgroup, 80 00:09:30,890 --> 00:09:34,640 these people who seem to not like the job that they're trying to do. 81 00:09:34,640 --> 00:09:42,740 So this is the in-group and outgroup, and the identity of these scientists is a wonderful, rational, knowledgeable, innovative people. 82 00:09:42,740 --> 00:09:46,940 The identity of the people is that they're much more holistic and intuitive, 83 00:09:46,940 --> 00:09:51,860 and the scientists don't like people because they think they're irrational and Luddite. 84 00:09:51,860 --> 00:09:57,920 And the people don't like the scientists because they think they're so reductionist, robotic, arrogant people. 85 00:09:57,920 --> 00:10:07,460 And you see this really clearly and a lot of the kinds of discussions that I've, you know, witnessed in this, the GM space. 86 00:10:07,460 --> 00:10:14,390 And actually, I think it's that that contributes to the persistence of the deficit model because the scientists, the in-group, 87 00:10:14,390 --> 00:10:20,810 it's part of their identity that they're knowledgeable and they know things and the people over there are a Luddite and stupid and don't know things. 88 00:10:20,810 --> 00:10:24,470 And so obviously, the difference between us is, I know this stuff. 89 00:10:24,470 --> 00:10:29,270 You don't know this stuff. And if only I tell you this stuff, then you will change your mind. 90 00:10:29,270 --> 00:10:36,680 And it's it's directly unhelpful to try to tackle this problem using this deficit model 91 00:10:36,680 --> 00:10:43,760 because it precisely ramps up the very differences that this model kind of defines. 92 00:10:43,760 --> 00:10:48,920 So, I mean, you can pass it out slightly differently in this science nature way. 93 00:10:48,920 --> 00:10:54,530 And if you're in the science group, reductionism is a good thing. It's a helpful tool to help you understand the system. 94 00:10:54,530 --> 00:10:59,180 You think you're fully rational, even though everybody knows that people are not fully rational and they shouldn't be 95 00:10:59,180 --> 00:11:03,650 fully rational because that's actually problematic for creativity and things like that. 96 00:11:03,650 --> 00:11:11,810 And scientists think they're terribly knowledgeable. And that is what kind of drives the arrogance. 97 00:11:11,810 --> 00:11:19,460 Mirror image of knowledgeable in in the opinion of the people on the other side of the divide who think that they have this much more sophisticated, 98 00:11:19,460 --> 00:11:21,200 holistic understanding of what's going on. 99 00:11:21,200 --> 00:11:33,080 That's that's clearly deeply intuitive and humble, and that that kind of narrative is what's branded as ignorance by the people on the science side. 100 00:11:33,080 --> 00:11:43,520 So somehow or other to get through this GM debate, we need to get through this false divide between science and nature. 101 00:11:43,520 --> 00:11:52,370 And I think it's particularly powerful and particularly difficult in the context of genetics and in this case, climate genetics. 102 00:11:52,370 --> 00:12:05,090 Because of the the the narratives that genetic, the geneticists have used to talk about their discipline over the years. 103 00:12:05,090 --> 00:12:11,300 So I'm particularly, for example, in the context of this reductionist, holistic paradigm. 104 00:12:11,300 --> 00:12:21,650 There is a. And narrative about genetics that it is highly reductionist, so if you go with some, you know, Wikipedia type definitions, 105 00:12:21,650 --> 00:12:27,470 the practise of analysing and describing a complex phenomenon in terms of simple fundamental constituents, 106 00:12:27,470 --> 00:12:33,110 especially when these are said to provide a sufficient explanation, there is a genetics narrative, 107 00:12:33,110 --> 00:12:40,940 which is that the DNA is the blueprint of life is a sufficient explanation, even when it is obvious that it isn't. 108 00:12:40,940 --> 00:12:48,230 And to me, as a geneticist, this holistic holism definition is exactly what genetics is about. 109 00:12:48,230 --> 00:12:56,470 It's the theory that parts of a whole are intimately connected with that whole and that they cannot exist independently of the whole. 110 00:12:56,470 --> 00:13:01,040 Then you can't understand without reference to the whole what's going on. 111 00:13:01,040 --> 00:13:08,780 And for me, genetics, particularly developmental genetics, which is where I've worked entirely. 112 00:13:08,780 --> 00:13:16,280 What's happening is an attempt to try to understand the relationship between things that you might call cults and the Oh, 113 00:13:16,280 --> 00:13:21,200 it's and it's about that information flow between the levels of organisation in the system. 114 00:13:21,200 --> 00:13:26,060 So one way you can think about that is in the context of the gene Typekit. 115 00:13:26,060 --> 00:13:33,650 That's the sequence of of the DNA, which is happening at this kind of scale nanomoles, not a nanometre type scales. 116 00:13:33,650 --> 00:13:39,680 And how that genotype relates to the phenotype, which is at the level of the whole organism, look like what is it doing? 117 00:13:39,680 --> 00:13:45,110 Which in the context of the plant, I work on this in this kind of tens of centimetre scale. 118 00:13:45,110 --> 00:13:49,520 And what we're trying to understand this is what these arrows are. 119 00:13:49,520 --> 00:13:55,790 Genetics is about understanding precisely the relationship between the parts at different levels of organisation 120 00:13:55,790 --> 00:14:02,210 is very difficult to say what the part is because always there's something smaller in something bigger. 121 00:14:02,210 --> 00:14:06,260 So is it a part or is it a whole depends on which direction you're going? 122 00:14:06,260 --> 00:14:14,270 And it's the dynamic interactions between those scales that's really resulting in this phenotype, 123 00:14:14,270 --> 00:14:21,920 which is an emergent property of anything of the genotype and itself contributing to building the genotype of the next generation. 124 00:14:21,920 --> 00:14:28,520 And this scales. This is. Actually, quite kind of phenomenally mind boggling. 125 00:14:28,520 --> 00:14:38,510 So this is a slight stolen from Rico Cohen, which points out that what we're talking about is the relationship between this and the world. 126 00:14:38,510 --> 00:14:43,010 I mean, this is this is many, many orders of magnitude that we're trying to map across. 127 00:14:43,010 --> 00:14:49,580 So to argue that genetics is reductionist when what you're trying to do is understand information 128 00:14:49,580 --> 00:14:55,790 flow across those kinds of scales is is extraordinary and yet deep in the narrative of genetics. 129 00:14:55,790 --> 00:15:07,260 Is this kind of deterministic, almost reductionist narrative which begins with, in some ways with Mendel, who is a hero because he really. 130 00:15:07,260 --> 00:15:16,260 A put into place the tools with which we could start to understand the relationship between the genotype from the phenotype. 131 00:15:16,260 --> 00:15:23,550 So I mean, a couple of sides kind of practically back to school on Mendel and maybe a thing that you didn't talk about in school, 132 00:15:23,550 --> 00:15:30,960 which is starch branching enzyme. But probably what you did talk about was round and wrinkled peas and Mendel's first floor, 133 00:15:30,960 --> 00:15:35,100 which says traits are governed by hereditary factors which exist in pairs. 134 00:15:35,100 --> 00:15:41,070 So you one from your mother, one from your father that you inherited and they don't mix during your life, 135 00:15:41,070 --> 00:15:44,370 but they segregate into your gametes, into the next generation. 136 00:15:44,370 --> 00:15:49,560 So everybody's kind of familiar with this is the pot with the round and the wrinkled peas. 137 00:15:49,560 --> 00:15:56,910 And if you cross a true breeding ground pea with a true breeding wrinkled pea, then the first generation are all round. 138 00:15:56,910 --> 00:15:57,990 But in the second generation, 139 00:15:57,990 --> 00:16:09,180 because of that independent separation of the of the gene you inherited from your mother in the junior inherited from your father. 140 00:16:09,180 --> 00:16:13,590 You wind up with the famous three to one round two wrinkled ratios. 141 00:16:13,590 --> 00:16:22,350 And so that relationship there between these hereditary factors, which immediately then sound like unitary parts, 142 00:16:22,350 --> 00:16:27,330 which are a sufficient explanation if you want to put it in that way for a phenotype. 143 00:16:27,330 --> 00:16:34,290 Way up here in terms of random and copy piece, that's also that's the kind of bedding in this notion of genetics is reductionist. 144 00:16:34,290 --> 00:16:41,160 But of course, now we know a lot more about what's going on, which is where starch branching enzyme comes into play. 145 00:16:41,160 --> 00:16:47,040 This gene encodes starch branching enzyme and in the wrinkled pea, it's mutant, so it doesn't work. 146 00:16:47,040 --> 00:16:52,440 So there is no gene for wrinkled. The gene for wrinkled is not having the gene for round. 147 00:16:52,440 --> 00:16:57,660 That's important. And if you don't have that gene when you're trying to build your, 148 00:16:57,660 --> 00:17:03,300 you fail to build your starch into more sugar, which is a building block of starch accumulates in the seed. 149 00:17:03,300 --> 00:17:08,070 And if there's more sugar at the time that the siege is maturing, they have this higher osmotic potential. 150 00:17:08,070 --> 00:17:13,500 So they suck up water and so that they are all kind of bougie, you say, growing with water. 151 00:17:13,500 --> 00:17:22,050 And then when they dry out, that water is lost and they wrinkle. And so a wrinkled pea is a wrinkled pea because of lack of starch branching enzyme. 152 00:17:22,050 --> 00:17:27,270 And you can draw a chain of events which looks very linear and maybe reductionist. 153 00:17:27,270 --> 00:17:31,650 But if you don't have starch branching enzyme, you don't make the RNA, you don't make the protein. 154 00:17:31,650 --> 00:17:34,350 Your starch synthesis is slowed, so you've got more sugar. 155 00:17:34,350 --> 00:17:43,860 So then I mean, but this is going on in the context of a whole organism which long here is a part is very hard to tell. 156 00:17:43,860 --> 00:17:51,330 There is, of course, all kinds of other stuff going on in the background. And then this wrinkled seed is building the next generation of peas. 157 00:17:51,330 --> 00:17:57,450 So again, although you can describe this in the very genes for reductionist way, this is what's happening. 158 00:17:57,450 --> 00:18:07,950 It's it fits, in my view, much better into this whole ISM debate, but also do some arithmetic. 159 00:18:07,950 --> 00:18:16,890 But this reductionist mystic has emerged in the way that we talk about genes we talk about genes for. 160 00:18:16,890 --> 00:18:23,010 We talk about the idea that there is a gene it maps on to a phenotype and it's a one for one thing. 161 00:18:23,010 --> 00:18:27,270 And it's it's a very deep feeling about anxiety. 162 00:18:27,270 --> 00:18:29,700 I think about genetic determinism, which in my view, 163 00:18:29,700 --> 00:18:35,640 is one of the reasons everyone's so excited about epigenetics because they view it as a kind of escape route from genetic determinism, 164 00:18:35,640 --> 00:18:46,140 rather than as a mechanism whereby gene expression is controlled, which we knew about already, and that genes for idea has been amplified. 165 00:18:46,140 --> 00:18:50,100 I think in the context of of the narrative around DNA sequencing. 166 00:18:50,100 --> 00:18:55,710 So genes are made of DNA. People talk about DNA, as I said all the time as being the blueprint for life. 167 00:18:55,710 --> 00:19:01,420 So if you had the sequence, you would be able to build the organism which you call out. 168 00:19:01,420 --> 00:19:05,160 The sequence by itself does nothing. You have to put it into a cell. 169 00:19:05,160 --> 00:19:12,660 The cell already has a huge amount of information in it. But admittedly was built using information that was in the DNA from the generation before. 170 00:19:12,660 --> 00:19:18,120 But this information is never naked, and you cannot build an organism out of a piece of DNA. 171 00:19:18,120 --> 00:19:23,190 You have to have the machinery that decodes that and rebuilds the cells. 172 00:19:23,190 --> 00:19:30,510 And so the blueprint analogies is that it contributes to this reductionist idea and it's problematic. 173 00:19:30,510 --> 00:19:37,830 And it then is extended to a blueprint for life with genes along it, like beads on a string. 174 00:19:37,830 --> 00:19:41,310 And you get this idea that genomes an amazingly fixed, 175 00:19:41,310 --> 00:19:47,640 organised things that behave beautifully in a kind of Prince Charles Nature's design kind of way. 176 00:19:47,640 --> 00:20:01,140 And it's just like that. And one really potent example of how it's just not like that is emerges from the work of Barbara McClintock, 177 00:20:01,140 --> 00:20:06,800 who using mice and especially maize kernels was able. 178 00:20:06,800 --> 00:20:14,990 You demonstrate effectively that there's bits of DNA that move about the genome is transposed by elements and you see them, 179 00:20:14,990 --> 00:20:19,160 you see the effects of them everywhere in your goals and in Snapdragons. 180 00:20:19,160 --> 00:20:23,960 Those patched particles of different colours are to do with bits of DNA, 181 00:20:23,960 --> 00:20:29,840 of hopping in and out of the genes that are required to make the pigments that coloured pencils. 182 00:20:29,840 --> 00:20:36,380 And so this instability in the genome is is very powerful and it's there. 183 00:20:36,380 --> 00:20:42,830 And in fact, Kathy Martin a number of years ago showed that the original almost certainly the original round and 184 00:20:42,830 --> 00:20:49,680 wrinkle mutation of Mendel was caused by the insertion of one of these transpersonal elements. 185 00:20:49,680 --> 00:20:58,830 And now that we have the sequences of of the genomes of of many crops, we know that they are absolutely stuffed full of these transposons. 186 00:20:58,830 --> 00:21:06,960 So this tiny bit at the top here in the all of the DNA sequences of of the wheat genome, 187 00:21:06,960 --> 00:21:13,500 the wheat is a hybrid of three different genomes, so it's actually got three genomes for abbey and genomes. 188 00:21:13,500 --> 00:21:22,530 And this bit up here is the genes. All the rest of the DNA is of the stuff, and these coloured bits are transposed with elements. 189 00:21:22,530 --> 00:21:30,390 So most of the genome is of wheat is made of these bits of DNA that in principle can cut themselves out and hop in and stick somewhere else. 190 00:21:30,390 --> 00:21:38,940 In practise, there are many mechanisms that keep them comparatively inactive, but nonetheless, the idea that you've got these beautiful, 191 00:21:38,940 --> 00:21:44,550 well-designed genome genes organised in a lovely way on a string, 192 00:21:44,550 --> 00:21:53,280 if it's nonsense and the way genomes work and the way they're organised is frankly a mess. 193 00:21:53,280 --> 00:22:06,180 And it's astonishing to my mind that they work at all and see how this fits into this notion of the way genetics works. 194 00:22:06,180 --> 00:22:15,090 This is kind of reductionist, rational thing is problematic and how it fits into the notion of how nature works. 195 00:22:15,090 --> 00:22:21,000 It's a beautiful, holistic design that is behaving in this beautiful race. 196 00:22:21,000 --> 00:22:28,650 That's also problematic that neither of these extremes, unsurprisingly, because extremes value are how things work. 197 00:22:28,650 --> 00:22:37,230 Neither of them are useful ways to think about the space and as well as the transposons jumping about the genome. 198 00:22:37,230 --> 00:22:46,200 Of course, there are many other mechanisms that are generating genetic variation within organisms, like when the DNA is copied, there are mistakes. 199 00:22:46,200 --> 00:22:52,950 Here are the transpose elements. There are big rearrangements in the genome that happen, particularly during the formation of the gametes, 200 00:22:52,950 --> 00:22:59,430 where bits of the crop, the chromosomes or paver to generate genetic variation. 201 00:22:59,430 --> 00:23:07,860 But that can go wrong so you can get bigger rearrangements. That's environmentally induced DNA damage that we all know about sunblock and so on. 202 00:23:07,860 --> 00:23:12,900 There are mistakes in that recombination process where the chromosomes was swapping over. 203 00:23:12,900 --> 00:23:20,430 When your repair mechanisms are doing your best to hope this mess together, they don't always work properly and they can make mistakes. 204 00:23:20,430 --> 00:23:26,790 And then, as I've described, there are actually hybridisation between species events, particularly in the plants, 205 00:23:26,790 --> 00:23:32,100 and there are whole genome duplications where you fail to make a cameo, but you nonetheless make a plant. 206 00:23:32,100 --> 00:23:39,270 And then there are also mechanisms for horizontal gene transfer where particularly microbes will, 207 00:23:39,270 --> 00:23:46,920 which make a living out of sticking their bits of DNA into genomes of plants and indeed animals, 208 00:23:46,920 --> 00:23:54,360 and then taking them back out again afterwards and then going and infecting another plant can move bits of DNA about between plants. 209 00:23:54,360 --> 00:24:00,150 So this idea of the beautiful genetic machine doesn't work. 210 00:24:00,150 --> 00:24:08,210 This is a. Not a very good way of encapsulating what's going on, but nonetheless, 211 00:24:08,210 --> 00:24:12,800 somehow it works if you are sitting in a room with all the mess that they're in and 212 00:24:12,800 --> 00:24:19,250 that kind of series of of mutational events that I talked about actually has driven. 213 00:24:19,250 --> 00:24:25,790 That's what underpins evolution, which also is kind of alluded to in the Prince Charles quote that there's been 214 00:24:25,790 --> 00:24:30,140 this kind of rigorous test of time over millions of years that is in theory, 215 00:24:30,140 --> 00:24:36,770 selected out the lovely, beautiful ones. And it is true that evolution has happened. 216 00:24:36,770 --> 00:24:45,110 This is true and that it's a mutation that underpins it and the difference between us. 217 00:24:45,110 --> 00:24:54,140 Watson and Crick and Chimpanzee are a number of mutations that have arisen over time in starting with the 218 00:24:54,140 --> 00:25:02,150 common ancestor of those two things and diverging along the the two lineages the chimpanzee and humans. 219 00:25:02,150 --> 00:25:10,070 And it is also true that which of those mutations is has survived is at least in part, 220 00:25:10,070 --> 00:25:18,260 although by no means in how determined by those that confer a successful phenotype on the organism. 221 00:25:18,260 --> 00:25:25,140 And this is the survival of the fittest notion of Darwin with which we are all very familiar. 222 00:25:25,140 --> 00:25:33,990 This is true. And so some of the quotes of Prince Charles, you might say then is in a in a good place. 223 00:25:33,990 --> 00:25:46,230 It is the case that that nature, if you want to put it that way, has picked out solutions to various problems that organisms face. 224 00:25:46,230 --> 00:25:52,050 But that also provides a very important cornerstone, I think, 225 00:25:52,050 --> 00:26:00,660 in the in the debate about the difference between the notion of science and nature as different ways of thinking about things. 226 00:26:00,660 --> 00:26:09,240 And the reason for that is because a lot of your ability to survive as the fittest has to do with your ability to defend yourself. 227 00:26:09,240 --> 00:26:13,590 So nature is red in tooth and claw. If you're a plant, 228 00:26:13,590 --> 00:26:19,590 it's not really the tooth and claw that so much of a problem as the slime and nasty 229 00:26:19,590 --> 00:26:24,400 digestive enzymes or indeed of our teeth and claws or teeth at least also involved. 230 00:26:24,400 --> 00:26:28,290 But nonetheless, you're a plant, particularly if you have to answer your rooted to the spot. 231 00:26:28,290 --> 00:26:33,330 You are complete sitting duck for all kinds of things and say plants that have survived have 232 00:26:33,330 --> 00:26:40,080 survived because they can defend themselves very strongly against all kinds of attacks. 233 00:26:40,080 --> 00:26:45,660 So in the real world, plants are poisonous or spiny or tough. 234 00:26:45,660 --> 00:26:56,520 And the notion that nature has provided all these wonderful things for us to eat and those natural foods must be the best is seriously problematic. 235 00:26:56,520 --> 00:27:05,460 It only works if you forget the plants and living organisms that are fighting for their own existence and trying to defend themselves hotly. 236 00:27:05,460 --> 00:27:10,620 And nobody says to their children, go into the woods and eat anything you can find. 237 00:27:10,620 --> 00:27:15,240 It's natural, so it must be good for you. It doesn't happen. 238 00:27:15,240 --> 00:27:24,030 And and that's I find it very interesting in some ways that this notion of nature is of a bounteous provider has 239 00:27:24,030 --> 00:27:34,200 arisen in in the context of a of a narrative that's about respecting nature and not putting humans ahead of nature. 240 00:27:34,200 --> 00:27:40,440 And yet, that narrative depends on the concept that humans are in some way ahead of nature. 241 00:27:40,440 --> 00:27:44,970 And that link, I think, is a very important leap to close. 242 00:27:44,970 --> 00:27:52,200 And fortunately for us, our ancestors over the last ten thousand years have noticed that natural plants are not very good for you. 243 00:27:52,200 --> 00:27:58,530 And so Darwin, as well as his work on natural selection, did quite a lot of work on domestication. 244 00:27:58,530 --> 00:28:07,890 So how you take an organism that has evolved under natural selection and chewed it through breeding to provide an organism 245 00:28:07,890 --> 00:28:16,470 that has evolved through human selection to deliver properties that are actually much more appropriate for what we need. 246 00:28:16,470 --> 00:28:21,990 So if you think about that in the context of a plant natural selection, 247 00:28:21,990 --> 00:28:29,070 if you were a plant is about allocating the resources that you have available to you, the nutrients that you capture, 248 00:28:29,070 --> 00:28:33,630 the photosynthesis that you do to minimise viable offspring, 249 00:28:33,630 --> 00:28:40,290 your grandchildren in the face of stiff competition from other plants and from things that are trying to eat you. 250 00:28:40,290 --> 00:28:43,650 So you are trying to collect as much resource as possible. 251 00:28:43,650 --> 00:28:51,750 Invest it as far as you possibly can in your grandchildren, Wolf defending yourself from the opposition and to do this. 252 00:28:51,750 --> 00:29:01,020 Plants have evolved with these complex multiscale regulars, regulatory systems that I alluded to, 253 00:29:01,020 --> 00:29:06,570 and those systems deliver really flexible growth habit that's adaptable depending on the 254 00:29:06,570 --> 00:29:11,490 environment in which the plant is growing and then all kinds of mechanisms to protect the plant, 255 00:29:11,490 --> 00:29:17,790 particularly the seed, which is the children, the plants, children and quite often indigestible or poisonous. 256 00:29:17,790 --> 00:29:21,830 They're also minimally resourced because that's a kind of bet hedging mechanism. 257 00:29:21,830 --> 00:29:26,400 If you want to make as many things as possible, all of which have a good chance of surviving. 258 00:29:26,400 --> 00:29:34,870 And your immobility also means that if you're not careful, all your children will will live in your house forever. 259 00:29:34,870 --> 00:29:40,350 And it's a much better idea to try and disperse them so you would like the seed to be dispersed of the pond. 260 00:29:40,350 --> 00:29:48,000 And that list of characteristics from the point of view of us wanting to get all food from plants is hopeless. 261 00:29:48,000 --> 00:29:52,920 And so human selection, which is about the survival of your favourite, 262 00:29:52,920 --> 00:29:59,100 is much more about allocation of the maximum amount of resource to the part that we want to eat, 263 00:29:59,100 --> 00:30:04,020 which for most of the calories that we eat, is the seed in cereals. 264 00:30:04,020 --> 00:30:13,470 We are not interested in plants investing in in competition because we want to grow them all in the field and we want to play nicely together. 265 00:30:13,470 --> 00:30:21,540 So we've actually removed a lot of those competitive mechanisms. We also don't really want them to label their seeds full of poisonous things. 266 00:30:21,540 --> 00:30:24,360 So we've had to. 267 00:30:24,360 --> 00:30:31,350 Who gave a lot of those natural defences as well over the eight to ten thousand years that we've been doing this domestication process. 268 00:30:31,350 --> 00:30:36,420 So you wind up with crop plants and crop plants. Nothing to do with natural plants. 269 00:30:36,420 --> 00:30:41,670 And they have less flexible growers, have it. They have this very lovely, digestible, nutritious said. 270 00:30:41,670 --> 00:30:46,290 The seed is usually retained on the plant so that you can harvest it and it's maximally resourced. 271 00:30:46,290 --> 00:30:51,090 And one of the most powerful illustrations of that is that this slide, 272 00:30:51,090 --> 00:30:58,830 which you may well have seen before here is Tucson Tea, which is the closest living wild relative of maize. 273 00:30:58,830 --> 00:31:07,170 There's still cross fertile, and here is maize, which has been produced as a result of the ingenious, 274 00:31:07,170 --> 00:31:15,480 very industrious activities of mostly Central American farmers over the last eight thousand years. 275 00:31:15,480 --> 00:31:20,820 This is natural. This is not natural. And whilst I work in the Sainsbury laboratory, 276 00:31:20,820 --> 00:31:30,390 that is the product in many ways of the success of the supermarket chain and also obviously the vision of David Sainsbury. 277 00:31:30,390 --> 00:31:36,990 I have to show this slide. Sainsbury's naturally sweet, sweet, cool. 278 00:31:36,990 --> 00:31:40,980 This is definitely not naturally sweet, sweet corn. 279 00:31:40,980 --> 00:31:49,740 This is the product of a thousand years of human ingenuity because this is plant babies and plants really don't want you to eat their babies. 280 00:31:49,740 --> 00:31:51,930 So this is unnaturally sweet, sweet corn. 281 00:31:51,930 --> 00:32:01,200 And that's a jolly good thing because I don't want to get my nutrition out of the naturally the natural equivalent because it is just not as good. 282 00:32:01,200 --> 00:32:10,830 It really isn't. So we've taken as a human race all of these lovely sources of genetic variation that are random that crop up, 283 00:32:10,830 --> 00:32:22,350 and we use that variation to select out plants that do better than the natural plants that providing the food that we want. 284 00:32:22,350 --> 00:32:29,250 And then we've very carefully mixed and matched the combinations of genetic variation that have arisen 285 00:32:29,250 --> 00:32:37,230 to assemble these linked lines that we have now are way better than their closest living relatives, 286 00:32:37,230 --> 00:32:41,760 providing the food that we want. And this then creates a problem for us. 287 00:32:41,760 --> 00:32:51,600 And that problem is that if we want to add yet another new characteristic into that plant like a disease resistance characteristics, 288 00:32:51,600 --> 00:32:58,770 for example, for a new disease, it's cropped up. It's a nightmare because you've got this genome with all the genetic variants that you want, 289 00:32:58,770 --> 00:33:03,960 that you've assembled into one plant and you'd like to add a gene that you found in the wild 290 00:33:03,960 --> 00:33:10,930 relative that gives the plant this resistance to the disease and you can cross them together. 291 00:33:10,930 --> 00:33:18,810 That's great. But then the next generation is a mixture of the genome from your elite line, plus the genome from your wild relative. 292 00:33:18,810 --> 00:33:25,560 And you have to spend an awful lot of time cleaning that up through back crossing so you you can take your early crop blind. 293 00:33:25,560 --> 00:33:29,010 You can cross it to the wild relative with some useful disease resistance. 294 00:33:29,010 --> 00:33:36,180 This is what it looks like the wild relative of maize and you get this 50 50 hybrid and then you have to take the children from that 295 00:33:36,180 --> 00:33:44,880 cross and back across it to the elite line over many generations until you gradually get to the point where you've got only the disease, 296 00:33:44,880 --> 00:33:56,130 or at least not much more of this wild relative genome in the in the breeding line that you're generating than just that disease resistance line. 297 00:33:56,130 --> 00:34:03,060 And it's a lot of work and so on. People over the last 50 years ask themselves, 298 00:34:03,060 --> 00:34:10,440 how can we increase the genetic diversity in these elite lines without having to do this mammoth crossing effort? 299 00:34:10,440 --> 00:34:15,180 And we came up. We've come up with a variety of mechanisms. In the 1960s, 300 00:34:15,180 --> 00:34:24,210 we started upping the rate of of of mutagenesis in these lines by deliberately antagonising them and treating the plants with 301 00:34:24,210 --> 00:34:33,090 mutations like MS or x rays or something just to increase the rate of mutation in the in the line that you wanted to start with. 302 00:34:33,090 --> 00:34:37,770 You still have to do a lot of cleaning up because you can wind up with mutations that were not the ones that you want, 303 00:34:37,770 --> 00:34:42,630 but it's less dramatic than having to cross in things from a wild relative. 304 00:34:42,630 --> 00:34:54,450 And then more recently, we've developed these fancy techniques for adding genes from other species, be they plants or even not plants. 305 00:34:54,450 --> 00:35:00,390 So you can Dillip to do what you might call deliberate horizontal gene transfer from another plant. 306 00:35:00,390 --> 00:35:07,770 And more recently, we found ways to target specific genetic changes, 307 00:35:07,770 --> 00:35:14,190 which are these rafted techniques that are going under the banner of genome editing. 308 00:35:14,190 --> 00:35:24,040 So these are potentially very useful tools in the in the breeders toolbox for adding genetic diversity into these elite lines that we have. 309 00:35:24,040 --> 00:35:35,590 These are very controversial approaches, and they are controversial because they are being rolled out in a narrative of science reductionist, 310 00:35:35,590 --> 00:35:45,130 rational thing vs. nature, holistic, intuitive thing, and they are firmly placed in this science box. 311 00:35:45,130 --> 00:35:49,270 And this science box is associated with profit driven agriculture, 312 00:35:49,270 --> 00:35:59,560 which is in turn associated with nasty effects for environmental sustainability, poor food safety, all of these things. 313 00:35:59,560 --> 00:36:10,200 And that's the problem. The problem is when you're trying to use these techniques in an environment where people's. 314 00:36:10,200 --> 00:36:18,720 Identity as as good people who are in favour of environmental sustainability and equitable distribution 315 00:36:18,720 --> 00:36:27,210 of benefits across the food supply chain are using GM as a badge that defines the group they don't like. 316 00:36:27,210 --> 00:36:34,440 And at the same time, the scientist group are fixed in in in this their identity, 317 00:36:34,440 --> 00:36:38,220 which is that they're knowledgeable and they know what to do and their rationalist and 318 00:36:38,220 --> 00:36:41,970 those people over there are irrational and they're not behaving in a sensible way. 319 00:36:41,970 --> 00:36:48,750 And so that the narrative on both sides of the fence of building the fence up moment by moment, 320 00:36:48,750 --> 00:36:53,430 which is why we wind up with this kind of behaviour at some level. 321 00:36:53,430 --> 00:36:56,970 And so the reason why we're back, 322 00:36:56,970 --> 00:37:06,360 I'm back talking about it now after years of kind of not talking about it for reasons I'll get onto in a minute is because the laws that 323 00:37:06,360 --> 00:37:18,390 the European Union has put into place to govern the use of GM crops are laws that are based very deeply on this science nature dichotomy. 324 00:37:18,390 --> 00:37:24,480 And this has come to the fore again because with the arrival of genome editing crops, 325 00:37:24,480 --> 00:37:33,720 the question has become which is an extraordinary indictment of the value of these laws or genome aged crops of GM or not. 326 00:37:33,720 --> 00:37:38,820 Because if they are GM, we should do this. And if they are not GM, we should do that. 327 00:37:38,820 --> 00:37:45,300 I find this extraordinary. But the method by which you've made your plant makes an enormous difference. 328 00:37:45,300 --> 00:37:53,160 But what you've done to it makes very little difference at all. So the current law goes like this. 329 00:37:53,160 --> 00:38:02,910 If you want to get a new variety of crop registered, an agricultural crop variety, you have to do, you have to get it onto an approved list. 330 00:38:02,910 --> 00:38:07,170 And to get it onto the list, you have to prove that it's a new variety. 331 00:38:07,170 --> 00:38:10,320 So it's distinct. It's not the same as what's out there already. 332 00:38:10,320 --> 00:38:15,540 You have to prove, prove that it behaves itself across the field and through generations. 333 00:38:15,540 --> 00:38:19,590 So it's uniform and it's stable. It behaves itself across generations. 334 00:38:19,590 --> 00:38:26,040 And there are organisations that will do these so-called ducie tests for you and allow you to certify your crop. 335 00:38:26,040 --> 00:38:34,950 If it's an agricultural crop. You also have to provide some evidence of equal value for cultivation and use, which is a piece you. 336 00:38:34,950 --> 00:38:41,370 And that means that there has to be something about this new variety that makes it better than than the existing varieties, 337 00:38:41,370 --> 00:38:45,310 and that's what you have to do to get your new varieties registered. 338 00:38:45,310 --> 00:38:51,790 Now on the government website, it says there are additional rules for genetically modified plants, 339 00:38:51,790 --> 00:38:59,770 and what that means is if you've made your plant fit, even if you can demonstrate its distinct uniform and stable and has value for cultivation 340 00:38:59,770 --> 00:39:06,310 using genetic modification and in the European Union now also using gene editing, 341 00:39:06,310 --> 00:39:14,230 then there is triggered a huge raft of additional safety tests and all kinds of things that you have to do if you didn't use those techniques. 342 00:39:14,230 --> 00:39:22,840 Find straight into the field, if you did use those techniques is of of extra testing and the rest of it. 343 00:39:22,840 --> 00:39:34,780 And that is because the EU law is explicitly balanced on this natural, unnatural, unnatural kind of dichotomy. 344 00:39:34,780 --> 00:39:40,000 So the law says that any approach to crop genetic improvement, 345 00:39:40,000 --> 00:39:46,300 but also certain genetic material in the way that does not occur naturally should be GM. 346 00:39:46,300 --> 00:39:55,750 And that includes what one might call traditional GM, but also the European Court of Justice recent ruling. 347 00:39:55,750 --> 00:40:01,120 Gene editing these new techniques because they would not occur naturally, whereas those random mutagenesis methods, 348 00:40:01,120 --> 00:40:09,370 because they've been around for a long time, are in an exemption clause because they're considered to have a long safety record. 349 00:40:09,370 --> 00:40:15,940 And there is now a massive rule going on following the European Court's ruling about 350 00:40:15,940 --> 00:40:19,330 whether it was the right ruling with the genome editing should or shouldn't count. 351 00:40:19,330 --> 00:40:25,510 And would there be a way possibly to get it into that exemption clause, or at least some of it into that exemption? 352 00:40:25,510 --> 00:40:33,700 I think the entire focus of the debate is wrong, and I can understand, you know, why with that. 353 00:40:33,700 --> 00:40:42,180 But. The law is based heavily on on these social identity paradigm, 354 00:40:42,180 --> 00:40:47,730 where people who want this wonderful set of common goals that everybody agrees have 355 00:40:47,730 --> 00:40:56,880 decided or have bought into the idea that the GM is in violation of these goals, 356 00:40:56,880 --> 00:41:07,200 and that's because of this natural science dichotomy. So the idea that the identity defining factors for that group of people are that big business 357 00:41:07,200 --> 00:41:13,110 can't be trusted to deliver the goals that we all agree on and that natural is good. 358 00:41:13,110 --> 00:41:23,700 And if we want to make any progress at all on moving towards a system so we never regulatory system that is based on this distinction, 359 00:41:23,700 --> 00:41:31,350 rather than based on actually achieving the goals and the fact that we've aligned the goals which we all agree on, 360 00:41:31,350 --> 00:41:37,410 we have this thing that we don't agree on is extraordinary to my mind. 361 00:41:37,410 --> 00:41:41,820 We should start with the thing that we all agree on and work forward from there, 362 00:41:41,820 --> 00:41:45,240 rather than stop the thing that we will disagree on and work backward from there. 363 00:41:45,240 --> 00:41:50,340 Because the legislation based on the thing that we disagree on on this natural unnatural 364 00:41:50,340 --> 00:41:58,080 is in a totally inadequate really in delivering the outcomes that we all agree on. 365 00:41:58,080 --> 00:42:07,440 It's not going to do it. It doesn't ask those questions. And the core of it is this natural is good kind of hypothesis. 366 00:42:07,440 --> 00:42:10,500 And if we're going to move forward with this debate, 367 00:42:10,500 --> 00:42:18,210 then we have to have the conversation about how we want to build a regulatory system that delivers the things that we all agree on, 368 00:42:18,210 --> 00:42:21,870 but doesn't require people to give up their identity. 369 00:42:21,870 --> 00:42:30,750 That doesn't deny people that that their identity is people who really care about the environment, 370 00:42:30,750 --> 00:42:37,290 about nature and about equity ability in the food supply chain, which is fine because we all agree on those things. 371 00:42:37,290 --> 00:42:43,590 So we need to discuss these solutions to food security using a narrative that's about holism. 372 00:42:43,590 --> 00:42:50,210 It's about intuition. It's about humanity. And it's about nature in some way. 373 00:42:50,210 --> 00:42:58,550 And that's actually really easy to do. It's very easy to talk about solutions to delivering food security that has nothing to do with 374 00:42:58,550 --> 00:43:04,190 GM because a huge proportion of what we need to do to deliver food security is not about GM. 375 00:43:04,190 --> 00:43:08,540 GM is not the is not the thing on which the whole thing pivots. 376 00:43:08,540 --> 00:43:15,920 We should be talking about the whole space. We should be talking about the requirement to reduce waste across the whole supply chain. 377 00:43:15,920 --> 00:43:22,370 We should be talking about the the contribution of meat consumption to reducing food security. 378 00:43:22,370 --> 00:43:30,200 We should be talking about all kinds of economic practises that we could introduce that would contribute to food security, 379 00:43:30,200 --> 00:43:32,990 but also crucially to the sustainability of the system. 380 00:43:32,990 --> 00:43:40,340 And yes, we can be talking about crop genetics as part of a whole raft of much more holistic interventions. 381 00:43:40,340 --> 00:43:46,850 And the fact that we are talking endlessly about GM is actually an incredibly reductionist argument and 382 00:43:46,850 --> 00:43:54,200 that people on the nature side of the of the of the line are also investing heavily in that argument. 383 00:43:54,200 --> 00:44:02,750 It tells you that something's gone wrong with the system. So that's one thing we can do talk about the supply and the food supply system holistically. 384 00:44:02,750 --> 00:44:10,340 The second thing we can do is talk about nature in a more humble way. 385 00:44:10,340 --> 00:44:15,920 So natural is only good for you. If you think that humans are the centre of the universe, 386 00:44:15,920 --> 00:44:23,690 if you acknowledge that nature is much broader than humans and that plants also have an agenda, 387 00:44:23,690 --> 00:44:31,250 then you move very rapidly and intuitively into a situation that acknowledges that natural is not good for you. 388 00:44:31,250 --> 00:44:40,940 And we need to talk about that. We need to talk about that. This framing of nature as a bounty of supply of urban needs is a human centric, 389 00:44:40,940 --> 00:44:47,690 arrogant way of talking about it, and we need to think about it more as an integrated system. 390 00:44:47,690 --> 00:44:56,330 So again, this is an argument that that plays well with people who care about those things and we do care about these things. 391 00:44:56,330 --> 00:45:03,530 And then we need to acknowledge as scientists that this kind of decision involves evidence from science. 392 00:45:03,530 --> 00:45:07,880 But it is actually not a decision that is about rational choice. 393 00:45:07,880 --> 00:45:15,050 It's a decision that is very heavily driven by values, and we as scientists are not good at that. 394 00:45:15,050 --> 00:45:22,460 I've heard so many scientists saying we need to move to a law that's more rational and we don't. 395 00:45:22,460 --> 00:45:30,110 We need to move to a law is more based on the values that people actually want to be delivered from the food system, 396 00:45:30,110 --> 00:45:36,230 which is this list of things on which we can all agree. So I think we can shift the debate. 397 00:45:36,230 --> 00:45:46,760 We can allow people to keep their identities as people who worry about the safety of the food chain and the the 398 00:45:46,760 --> 00:45:55,550 sustainability of of our activities on this planet by replacing natural is good as a paradigm which doesn't work, 399 00:45:55,550 --> 00:46:02,880 doesn't deliver the values that people say they hold for a more general statement that values really matter. 400 00:46:02,880 --> 00:46:11,490 And this set of this list, identity defining factors, I think, is in this that most people could buy into. 401 00:46:11,490 --> 00:46:16,120 And it's very clear that the current regulatory system does not address this list. 402 00:46:16,120 --> 00:46:22,500 It addresses something altogether different because it's very heavily based on this natural is good paradigm. 403 00:46:22,500 --> 00:46:36,330 And so we could move to a much more robust regulatory system for crops that would allow a much more would support the shared goals that we all hold. 404 00:46:36,330 --> 00:46:45,390 But you shouldn't be able to introduce a new crop that's not in some way consistent with these widely agreed goals and that the product, 405 00:46:45,390 --> 00:46:53,820 the crop itself is what matters and what it does to contribute to these goals and the method by which you made it is not important. 406 00:46:53,820 --> 00:46:59,820 Now, obviously, the method by which you made it could have an impact on its safety, 407 00:46:59,820 --> 00:47:04,680 for example, the unintended effects of whatever intervention it was that you made, 408 00:47:04,680 --> 00:47:10,020 be that through conventional breeding or through the most fancy up-to-date technique you could possibly imagine. 409 00:47:10,020 --> 00:47:17,100 But the primary issue is what the crop does and what it is, not how you made it. 410 00:47:17,100 --> 00:47:22,740 And so you can imagine a system that that builds on our current registration system, 411 00:47:22,740 --> 00:47:27,900 which is not quite the same as the regulatory system where we ask about distinct uniform and stable. 412 00:47:27,900 --> 00:47:37,440 And we ask about value for cultivation and use in a much broader way that is based around these common goals for food production that we share. 413 00:47:37,440 --> 00:47:47,520 And then we, for every single new variety, introduce a question about risk. 414 00:47:47,520 --> 00:47:53,730 And based on the answer to an initial, fairly low level risk assessment, 415 00:47:53,730 --> 00:48:02,700 we can then trigger tiered additional risk assessment methods of methods that would cover all new crops and therefore genuinely 416 00:48:02,700 --> 00:48:10,980 deliver these kinds of common goals of environmental sustainability and safety because the current law simply doesn't do it. 417 00:48:10,980 --> 00:48:26,820 And to my mind, now is quite an important moment to to do this with the whole everything is is so unstable politically and this. 418 00:48:26,820 --> 00:48:33,750 Which is scary, but I think also creates the opportunity to do things that are quite disruptive. 419 00:48:33,750 --> 00:48:37,830 And this kind of approach is an approach that's a unifying approach. 420 00:48:37,830 --> 00:48:39,480 It starts with common goals. 421 00:48:39,480 --> 00:48:46,890 And I think if there's anything we need in this country just at the moment and indeed in this continent, it's things that bring people together. 422 00:48:46,890 --> 00:48:51,540 So I think taking an approach to regulation in the food system that does that, 423 00:48:51,540 --> 00:48:57,390 that starts with things that everybody can buy into is the way we need to move forward. 424 00:48:57,390 --> 00:49:16,300 And I think we have the opportunity to do that, which we should seise. Thank you. 425 00:49:16,300 --> 00:49:23,530 So I'd like to thank Autoline for a really fabulous talk. Just before we have questions to remind you that we are broadcast. 426 00:49:23,530 --> 00:49:32,380 And if there are any royals who would like to email in the question, then I'm sure we'll be very happy to answer royals questions. 427 00:49:32,380 --> 00:49:39,880 We have a question in on the Isle of Wight if he could wait for the. 428 00:49:39,880 --> 00:49:49,630 Thank you. Do you agree that it's bad enough chattering classes objecting to us producing GM crops in our own country? 429 00:49:49,630 --> 00:49:59,020 But is it even worse than preventing Third World countries from getting a drought resistant crops and so on? 430 00:49:59,020 --> 00:50:06,220 Vice President Mike Pence and prejudices around the world. 431 00:50:06,220 --> 00:50:16,960 Absolutely, I think one of the the outcomes of the highly contentious debate in the developed world where we have enough food has 432 00:50:16,960 --> 00:50:26,390 been to slow the deployment of whatever tools people in developing countries want to improve their agricultural systems, 433 00:50:26,390 --> 00:50:34,180 and there are many and different approaches they could use. But my view is this is a tricky, complex problem. 434 00:50:34,180 --> 00:50:35,950 It's a holistic type problem. 435 00:50:35,950 --> 00:50:45,370 We have a whole variety of different ways in and all of these tools should be available to us and we should use the right ones for the right jobs. 436 00:50:45,370 --> 00:50:49,960 Thank you. Question there. And thank you very much. 437 00:50:49,960 --> 00:50:56,380 Nice. Good topic. I was thinking that this house, I believe Brexit, the whole situation. 438 00:50:56,380 --> 00:51:10,690 And anyway, my question is, isn't the issue really that the companies that obtain benefit financial benefits have got too much power on scientists? 439 00:51:10,690 --> 00:51:14,200 Because most of these are legally bound and non-disclosure agreements, 440 00:51:14,200 --> 00:51:25,810 they lose their job if they took and by the people and by the pure fact that they are driven by financial gain with very little recourse. 441 00:51:25,810 --> 00:51:30,890 Sometimes for people who get damaged by what they are doing to. 442 00:51:30,890 --> 00:51:43,300 To bring some retribution for these companies is an estimate that I have a more robust regulatory system that controls patents that controls. 443 00:51:43,300 --> 00:51:51,610 Either formal or informal controls, the way in which this thing are necessary to avoid a situation that is happening now, 444 00:51:51,610 --> 00:51:56,440 which is people are taking things when they take extremes, they just fight each other. 445 00:51:56,440 --> 00:52:00,420 If you are not or if you're if you're going to read, you are wrong. 446 00:52:00,420 --> 00:52:08,690 In the case of a stronger regulation and political efforts to have signed this approach disclosure, 447 00:52:08,690 --> 00:52:13,290 except that it is needed to try to bring the two sides together. 448 00:52:13,290 --> 00:52:16,720 I think there are a number of very interesting points that you've made, 449 00:52:16,720 --> 00:52:25,870 and I think it's certainly true that the the way that the landscape has been divided up has indeed made things worse. 450 00:52:25,870 --> 00:52:32,440 So an example for that is that because GM is classified as a kind of different special thing, 451 00:52:32,440 --> 00:52:39,190 it's actually the kind of patent protection you can get as a breeder or as a company on it is much more, 452 00:52:39,190 --> 00:52:47,980 much more rigorous than the classic breeders rights protection, which allow people to continue to use your for your lines in breeding. 453 00:52:47,980 --> 00:52:54,310 And that division has come about because of this definition of GM as a sort of different thing. 454 00:52:54,310 --> 00:53:01,630 And so again, if we if we roll that out level the playing field and it was everything was regulated in the same way. 455 00:53:01,630 --> 00:53:10,750 I think we would have more opportunities indeed to, you know, to to create a system that genuinely delivers what people want, 456 00:53:10,750 --> 00:53:17,450 including proper scrutiny on the behaviour of companies that people are worried about. 457 00:53:17,450 --> 00:53:23,330 Questions back a bit provocative. Thank you very much. 458 00:53:23,330 --> 00:53:33,860 Excellent presentation. Do I understand you right that you're one of the few scientists in Oxford and Cambridge who actually 459 00:53:33,860 --> 00:53:44,270 see an opportunity and Brexit by being able to break out of the GM restrict Europe GM regulations? 460 00:53:44,270 --> 00:53:57,350 So I am interested in the whole of the European Union being able to build a regulatory system that supports these common goals that we all have. 461 00:53:57,350 --> 00:54:02,570 There are a number of my colleagues who have expressed the view in the way that you've expressed it. 462 00:54:02,570 --> 00:54:08,540 I've heard people more or less saying, Hooray, the silver lining is now we can have GM. 463 00:54:08,540 --> 00:54:12,740 And to me, that is fundamentally the wrong way to go about it. 464 00:54:12,740 --> 00:54:21,830 I'm I'm not. I mean, I'm genuinely, genuinely of the opinion that what we need is a regulatory system that rolls in all of these safety issues, 465 00:54:21,830 --> 00:54:31,040 of course, but these value judgements. And if that winds up not using very much GM, I'm I'm okay with that. 466 00:54:31,040 --> 00:54:33,170 I'm not about yes, we have to have GM, 467 00:54:33,170 --> 00:54:45,440 I'm about how can we build a system that actually gives people what they want and assesses the value to delivering these goals of safe, 468 00:54:45,440 --> 00:54:49,910 affordable, nutritious food in a way that that is yeah, 469 00:54:49,910 --> 00:54:55,670 it's robust and genuine rather than the current system, which simply doesn't even address those questions. 470 00:54:55,670 --> 00:55:04,910 So I'm not sorry. I'm not willing to rise to your provocative challenge, but thank you for the question. 471 00:55:04,910 --> 00:55:12,290 When you say that, like the method by which you make the crop is not important or like that, the tools are not available to everyone. 472 00:55:12,290 --> 00:55:18,920 I feel like, um, like I feel like a lot of the hesitancy that comes from people who are sceptical about science, 473 00:55:18,920 --> 00:55:22,340 who are making these like nature versus science. Arguments, as you put it, 474 00:55:22,340 --> 00:55:29,540 is from like recognising that the socio economic area that we live in make it 475 00:55:29,540 --> 00:55:33,710 so that not everyone has access to these same like genetic tools are like, 476 00:55:33,710 --> 00:55:42,070 these are expensive, like gene editing or gene gene sequencing facilities. 477 00:55:42,070 --> 00:55:51,230 It might like historically that these like places like academic institutions and places where science, like with the capital as happens, 478 00:55:51,230 --> 00:56:02,870 is done to profit, industrial agriculture and, for example, not like small farmers or not in an equitable way as you say it. 479 00:56:02,870 --> 00:56:10,820 And that might be the reason why I like the treatment of like that crossing or traditional types of plant breeding is different from like GM, 480 00:56:10,820 --> 00:56:20,480 just because of this difference, difference in access and difference in like products that result from these different techniques. 481 00:56:20,480 --> 00:56:25,430 Not saying that, like intrinsically, there's something about those techniques that make one bad and one good, 482 00:56:25,430 --> 00:56:31,160 but rather that just because of the society that we live in, this sort of like discrepancy exists. 483 00:56:31,160 --> 00:56:38,090 So I mean, that is a very interesting point. But again, this is another case where there's a kind of deep irony in the system, 484 00:56:38,090 --> 00:56:44,630 which is that the reason using GM in a in an agricultural in a crop breeding context is so 485 00:56:44,630 --> 00:56:51,470 expensive is is the regulatory hurdles that you have to jump through to get your crop registered. 486 00:56:51,470 --> 00:56:55,910 But actually, making the crop is really not that expensive anymore. 487 00:56:55,910 --> 00:57:03,110 There's a lot of money invested in universities in understanding which genes you might want to to look at, 488 00:57:03,110 --> 00:57:06,770 but that's mostly open access data that anybody can get ahold of. 489 00:57:06,770 --> 00:57:11,870 And certainly a fairly widely available. 490 00:57:11,870 --> 00:57:20,840 That's not the the the it's investing in the research and academic institutions generates a lot of data that's available to everybody. 491 00:57:20,840 --> 00:57:24,830 But the techniques of genome editing and GM, they're not trivial, 492 00:57:24,830 --> 00:57:32,240 but the kinds of countries that would be interested in developing crops for smallholder farmers and so on. 493 00:57:32,240 --> 00:57:40,160 They they are perfectly capable of using those technologies. It's not they're not out of the realm of possibility. 494 00:57:40,160 --> 00:57:44,210 And the hurdle at the moment is that, you know, 495 00:57:44,210 --> 00:57:49,160 the reason it's mostly these big companies using the approaches is it's so expensive to get 496 00:57:49,160 --> 00:57:53,750 the crops licenced because you have to jump through all of those those kinds of hurdles. 497 00:57:53,750 --> 00:58:02,510 So I think the question of of cost is important, but it doesn't play out quite in the way that you suggest. 498 00:58:02,510 --> 00:58:09,290 And a number of charities have invested quite heavily in trying to get particular applications out there, 499 00:58:09,290 --> 00:58:17,020 and it costs a huge amount of money because of all the testing you have to do, which is unfortunate in many ways. 500 00:58:17,020 --> 00:58:25,180 Question at the back there. And you mentioned that improving crop genetics is one of four ways towards food security. 501 00:58:25,180 --> 00:58:33,670 I was just wondering whether you can illustrate with an example of some of the most kind of outstanding. 502 00:58:33,670 --> 00:58:39,700 Crops or whatever tools or resources that are being considered currently, and so there are many things that we have to do anything, 503 00:58:39,700 --> 00:58:44,650 Charles is one of the people who've thought very hard about what one might have to do to to improve 504 00:58:44,650 --> 00:58:50,800 food security for many people in the audience could help and in the context of crop genetics to my. 505 00:58:50,800 --> 00:58:56,950 So there are lots of things to say for GM. 506 00:58:56,950 --> 00:59:02,890 Many of the kinds of things you can do with GM are things where it is a single gene that makes a big difference. 507 00:59:02,890 --> 00:59:07,570 And there are quite a number of those things. But there are also traits like drought resistance, 508 00:59:07,570 --> 00:59:11,680 where actually probably the most robust drought resistance is more likely to come out 509 00:59:11,680 --> 00:59:17,770 of rather more complex multi gene assemblages and conventional breeding approaches, 510 00:59:17,770 --> 00:59:24,040 or assisted micro assisted breeding approaches might be a better way to achieve those. 511 00:59:24,040 --> 00:59:28,750 In the context of things you can definitely do now with GM, that will be super helpful. 512 00:59:28,750 --> 00:59:32,980 Right up there is disease resistance because there are really well known, 513 00:59:32,980 --> 00:59:40,750 really well understood genes that absolutely will convey resistance to serious pests 514 00:59:40,750 --> 00:59:45,220 and pathogens that are out there that are spreading because of climate change issues. 515 00:59:45,220 --> 00:59:51,100 And we really could deploy those pretty quickly if we had a different regulatory landscape. 516 00:59:51,100 --> 00:59:59,500 And I know people who work in that disease resistant field are particularly frustrated by the difficulty in moving forward with that. 517 00:59:59,500 --> 01:00:09,820 And so to me, that disease resistance would probably be top of the list of things I would want to do with the genome editing or GM kind of now. 518 01:00:09,820 --> 01:00:18,400 Kenny, I'm going to ask you about genetics and particularly the this kind of reductionist, holistic dichotomy. 519 01:00:18,400 --> 01:00:25,030 I hasten to add I'm not a geneticist, as you will probably be revealed in a moment. 520 01:00:25,030 --> 01:00:31,960 But one of the kind of most compelling narratives which I've taken on board 521 01:00:31,960 --> 01:00:40,900 around genetics is the Richard Dawkins selfish gene blind watchmaker analogy. 522 01:00:40,900 --> 01:00:50,830 And that seemed to be very interesting because it demonstrates how you can create lots of diversity from very simple, deterministic rules. 523 01:00:50,830 --> 01:00:56,950 But from what you've just said, that may actually be a corruption of our understanding. 524 01:00:56,950 --> 01:01:03,160 It's certainly an extremely deterministic reductionist version is ultimately reductionist. 525 01:01:03,160 --> 01:01:10,780 So is if we got the wrong end of the stick by reading Dawkins. 526 01:01:10,780 --> 01:01:22,000 So one of this is there's a whole nother talk I could give about what you might call systems biology. 527 01:01:22,000 --> 01:01:26,170 So, so biological systems are complex. 528 01:01:26,170 --> 01:01:33,580 They involve information moving both up the levels of organisation and down the levels of organisation, 529 01:01:33,580 --> 01:01:36,820 and they involve huge amounts of feedback driving those systems. 530 01:01:36,820 --> 01:01:43,480 So, you know, you can you can encapsulate that's a little bit in the in the concept of what came first, the chicken or the egg. 531 01:01:43,480 --> 01:01:52,390 And that's what is kind of rolled out infinitely many times in the in the life of a of a of an organism. 532 01:01:52,390 --> 01:01:57,370 So and those feedbacks are really interesting, 533 01:01:57,370 --> 01:02:03,700 and they're the things that generate a lot of the robustness that we've managed to achieve as organisms, 534 01:02:03,700 --> 01:02:10,280 despite the fact that our genomes are so messy. And why is this relevant? 535 01:02:10,280 --> 01:02:14,950 It's relevant because those concepts are actually quite difficult for people to deal with. 536 01:02:14,950 --> 01:02:18,130 People really like linear narratives. 537 01:02:18,130 --> 01:02:24,730 That's how you can best understand anything a story that has a beginning, a middle and an end where where you're going along. 538 01:02:24,730 --> 01:02:31,840 And Dawkins is a master of taking complex issues and rolling them out into a very compelling linear narrative, 539 01:02:31,840 --> 01:02:37,420 which is why he's such a good science communicator. But science, none of the things he's talking about a linear. 540 01:02:37,420 --> 01:02:44,410 And so then you get from the same benefits of talking about them in this and very engaging way. 541 01:02:44,410 --> 01:02:55,420 The misapprehension that things are deterministic in that sense and that the information is flowing always in that linear way was seen in feedbacks. 542 01:02:55,420 --> 01:03:04,150 And it's that in the wider society, but it's also actually there in the in scientific community as well. 543 01:03:04,150 --> 01:03:10,630 Moving people through into thinking in terms of of complex dynamical systems is difficult. 544 01:03:10,630 --> 01:03:15,300 And to understand that you really have to to collaborate with mathematicians. 545 01:03:15,300 --> 01:03:22,450 And it's a very exciting time to be doing biology precisely because we're at the phase when we have enough information about 546 01:03:22,450 --> 01:03:30,370 the parts at various different scales to begin to understand how they work in these in these dynamical systems type modules. 547 01:03:30,370 --> 01:03:38,590 The thing the organism cares about all those systems and their system level properties that the nature of the parts is almost irrelevant. 548 01:03:38,590 --> 01:03:42,670 What you want is a way to, you know, grow root in that direction. 549 01:03:42,670 --> 01:03:47,860 If there's nutrients over there, you don't care what the parts are. You care about the behaviour of the system. 550 01:03:47,860 --> 01:03:56,430 And it's it's the same problem of parts and holes and how they relate to one another playing out in very different contexts. 551 01:03:56,430 --> 01:04:03,340 And we have to find ways as humble people to deal with those kinds of complexities because 552 01:04:03,340 --> 01:04:07,600 all of the problems that we're trying to face in the world are problems of that sort. 553 01:04:07,600 --> 01:04:16,210 And there's a lot of interesting work going on in government on on how you use the more systems approach to address some of these tricky problems. 554 01:04:16,210 --> 01:04:23,650 But if I might just defend Oxford Biology to my engineer friend at the end of that extraordinary graph you showed of the of 555 01:04:23,650 --> 01:04:32,500 the wheat genome with 80 percent due to transpose elements that that's 80 percent or Kenzi and selfish genes going through. 556 01:04:32,500 --> 01:04:42,490 You know, there's a question that, yes, we we had a very interesting talk some months ago in this room by a senior government adviser, an economist, 557 01:04:42,490 --> 01:04:49,690 and one of the very interesting point she made was the difficulty was that the regulators and particularly the elected representatives, 558 01:04:49,690 --> 01:04:58,330 were some 40 years behind the science, the current science because of the nature of they weren't specialists, in other words. 559 01:04:58,330 --> 01:05:06,670 I'm wondering whether you feel that that might be a problem when it comes to the kind of regulation and more to the point public debate, 560 01:05:06,670 --> 01:05:17,860 you're talking about that, actually. A lot of the debaters and the regulators are way behind the real up to date science. 561 01:05:17,860 --> 01:05:23,780 So I could there are a number of things I can say about that. 562 01:05:23,780 --> 01:05:28,750 At some level that's a deficit model argument. If only those people knew it would be all right. 563 01:05:28,750 --> 01:05:33,070 And so at some level, I would reject that. 564 01:05:33,070 --> 01:05:40,520 The reason you go to that kind of regulation is not because you don't know the science, it's because you think. 565 01:05:40,520 --> 01:05:52,370 Natural is good, which is different, and that's underpinned by a kind of different rationale really than than I need to know the detailed science. 566 01:05:52,370 --> 01:06:00,140 So that's the first thing. The second thing, I spend a fair amount of time on various kinds of science advice mechanisms. 567 01:06:00,140 --> 01:06:05,540 And I I think there are good ways to get high quality science into government. 568 01:06:05,540 --> 01:06:13,610 The thing that is frustrating that I think is beginning to move with these ideas about system thinking and government is another thing that is, 569 01:06:13,610 --> 01:06:19,670 you know, rolled out across society that I've just described is this desperate desire for 570 01:06:19,670 --> 01:06:25,040 linearity for I do this and then this will happen and it will happen in a linear way. 571 01:06:25,040 --> 01:06:29,240 So an awful lot of policymaking winds up asking the question, OK, 572 01:06:29,240 --> 01:06:35,690 what will the intervention be and how will I measure whether it's been effective and how will I demonstrate that is my intervention here? 573 01:06:35,690 --> 01:06:42,650 That's made it effective over that. And when you're talking about these kinds of complex systems, 574 01:06:42,650 --> 01:06:50,990 that's that linearity is not going to happen and you're going to have to be willing to risk or to to, 575 01:06:50,990 --> 01:06:55,520 yeah, to believe the evidence that you've put together that this intervention will work. 576 01:06:55,520 --> 01:07:00,170 But it will only work after you've waited for some amount of time for something critical to build up in the system. 577 01:07:00,170 --> 01:07:06,830 And then there'll be a tipping point in the work suddenly. And so you'll have to wait for several years while nothing happens patiently. 578 01:07:06,830 --> 01:07:16,520 And and so the role of, again, this kind of complex system modelling in developing policy has become very important. 579 01:07:16,520 --> 01:07:25,430 And that's where I find there's more difficulty is getting people to buy into that narrative because because the 580 01:07:25,430 --> 01:07:34,430 linear narrative is so much more appealing and the desire to do something effective is is so kind of deep and, 581 01:07:34,430 --> 01:07:40,220 you know, reasonably embedded in the system that you want to be able to demonstrate that that's working now. 582 01:07:40,220 --> 01:07:46,940 And so a lot of these very human issues about the way people think and the way 583 01:07:46,940 --> 01:07:50,720 they make decisions that we we kind of need to understand and work around. 584 01:07:50,720 --> 01:07:58,500 And that's true for the people giving the advice as well as for the people who are needing to enact it. 585 01:07:58,500 --> 01:08:05,320 I'm not sure how much time we've got the environmental movement has seems to have used science very strongly 586 01:08:05,320 --> 01:08:10,090 and I wonder whether were there any lessons that you could see from this area that could be drawn from that? 587 01:08:10,090 --> 01:08:15,310 I mean, obviously people don't trust industry, but they do seem to trust scientists in that in that setting. 588 01:08:15,310 --> 01:08:24,020 And there's there's a narrative in the story. I wondered whether this compare and contrast the two, the two areas, perhaps. 589 01:08:24,020 --> 01:08:32,730 Yeah, so. The environmental movement did use science. 590 01:08:32,730 --> 01:08:43,230 They they tend to use it in a way that suits them, rather than necessarily in a way that takes into account all the evidence. 591 01:08:43,230 --> 01:08:53,310 So there are powerful actors in the environmental movement that are still campaigning against things like GM and of an outcome of that as being. 592 01:08:53,310 --> 01:08:59,280 People have come out of those organisations and are now campaigning rapidly for GM because they feel that the 593 01:08:59,280 --> 01:09:06,480 environmental movement is potentially compromising itself by picking and choosing which evidence it likes. 594 01:09:06,480 --> 01:09:14,940 And so, you know, the extent I'm not making climate change. 595 01:09:14,940 --> 01:09:21,810 Exactly. Exactly so. So lots of it means that that that's exactly where the debate has happened. 596 01:09:21,810 --> 01:09:23,700 Climate change, you know, 597 01:09:23,700 --> 01:09:30,210 there are there are people over here who don't believe the evidence and the environmental movement is driving forward with that evidence. 598 01:09:30,210 --> 01:09:35,760 But you can, you know, the tables are completely turned when it comes to various other technologies. 599 01:09:35,760 --> 01:09:44,880 And I must say, I think it's, you know, a lot of what the environmental movement does is is common. 600 01:09:44,880 --> 01:09:50,490 I mean, they they are powerfully motivated to drive these very important agendas forward that 601 01:09:50,490 --> 01:09:56,430 really it's really important that climate change moves up the agenda in all kinds of ways, 602 01:09:56,430 --> 01:10:06,270 and they're very effective at doing that. I I worry that there. 603 01:10:06,270 --> 01:10:12,780 Need to keep that kind of community together, which is the nature is good, science is bad community, 604 01:10:12,780 --> 01:10:20,310 even though they're using scientific evidence and it compromises their ability to make arguments 605 01:10:20,310 --> 01:10:25,380 in other parts of the space where there's a clash between the the nature and the science. 606 01:10:25,380 --> 01:10:29,820 And that could be seriously problematic because we need those strong environmental 607 01:10:29,820 --> 01:10:34,260 campaigning organisations and we need their integrity to be absolutely robust. 608 01:10:34,260 --> 01:10:38,880 And to me, it's not always clear currently that it is. 609 01:10:38,880 --> 01:10:42,510 And a last question, Chris. Thanks. Thanks, Charles. 610 01:10:42,510 --> 01:10:51,900 GM and gene editing are relatively new techniques that come with risks, and people are worried about those risks. 611 01:10:51,900 --> 01:10:59,760 Has the science community itself been honest about those risks, either inside industry or outside industry? 612 01:10:59,760 --> 01:11:06,850 And has it communicated that well enough so. 613 01:11:06,850 --> 01:11:19,480 Anything new comes with risks, but actually, and I think old quite often also has risks that are not that are kind of taken as as part of the scenery. 614 01:11:19,480 --> 01:11:28,360 So I think it's difficult to argue that the risks associated with the techniques themselves 615 01:11:28,360 --> 01:11:36,070 are greater than the risks associated with a lot of conventional breeding approaches. 616 01:11:36,070 --> 01:11:42,550 Inasmuch as you're introducing genetic change into this very messy genome, all the rest of it now, 617 01:11:42,550 --> 01:11:48,140 the genes that you introduce or the genes that you change and the effects that those have. 618 01:11:48,140 --> 01:11:51,920 Of course, and those need assessing, 619 01:11:51,920 --> 01:11:56,630 but that's also true in the context of convention meetings so that the example I 620 01:11:56,630 --> 01:12:01,730 like to use is there's been a huge amount of debates about herbicide tolerance, 621 01:12:01,730 --> 01:12:05,600 which is one of the main GM traits out there. 622 01:12:05,600 --> 01:12:11,120 And if you can have all kinds of discussions about whether it's a good trait or a bad trade. 623 01:12:11,120 --> 01:12:17,240 But the general idea is you make your crop resistant to a weed killer. You can spray that he'd fill with weed killer. 624 01:12:17,240 --> 01:12:21,890 The crop survives, the weeds die, and it's very helpful for weed control. 625 01:12:21,890 --> 01:12:31,490 You can make herbicide resistant crops, single gene herbicide resistant crops using those techniques that are on the eve of a completely conventional 626 01:12:31,490 --> 01:12:37,340 side or the mutagenesis side that don't involve any of the safety regulations and the risk assessments. 627 01:12:37,340 --> 01:12:41,420 So you've got two types of single gene, herbicide tolerant crop. 628 01:12:41,420 --> 01:12:44,540 One of them millions of hoops to jump through to get to into the field. 629 01:12:44,540 --> 01:12:51,110 The other is in the field tomorrow, and there are risks associated with both of those things. 630 01:12:51,110 --> 01:12:57,260 These risks are being assessed. These risks are not being assessed, and I think that's a problem. 631 01:12:57,260 --> 01:13:06,110 I agree with you completely that all of us need to be as honest as we possibly can about risk. 632 01:13:06,110 --> 01:13:16,220 But at the same time that that that the idea that there is risk associated with something new doesn't diminish 633 01:13:16,220 --> 01:13:21,320 the fact that there is risks associated with something old and risk is got to be assessed relatively. 634 01:13:21,320 --> 01:13:28,130 Is it more or less dangerous than what we're doing already? And that, I think, is a very important element. 635 01:13:28,130 --> 01:13:34,760 And then on top of that, you've got your values. Is it going to help you deliver those common goals or not? 636 01:13:34,760 --> 01:13:39,320 And those both of those things we need to ask in both of those contexts? 637 01:13:39,320 --> 01:13:46,880 So just before thanking Autoline, let me tell you about the last in our series of talks, which is next week by Florian Freund. 638 01:13:46,880 --> 01:13:53,990 And that's on the fifth next week, Thursday, and it's Brexit, agriculture and dietary risks in the UK. 639 01:13:53,990 --> 01:14:04,400 So continuing with some of the things and offering grew up in Oxford and mother, father and brother are all mediaeval historians, I believe. 640 01:14:04,400 --> 01:14:10,640 I think that we should be extremely grateful that Autoline has been a rebel since childhood and broke all 641 01:14:10,640 --> 01:14:15,590 sorts of familial norms to become a scientist and and it was just simply wonderful thought this evening. 642 01:14:15,590 --> 01:14:32,209 Many thanks indeed.
