I think Mark is very brave to admit his mistakes and be able to embrace them and come forward to such a large crowd. I think it was almost better for him to start out the way he did because it gave him a better understanding of why GMOs were good and it also showed him why people think they are bad. So now he can help inform those people and people around the world the right way and explain it to them how he learned about it and why he changed. He makes his case by saying when he thought about GMOs he just thought about evil scientists working in a lab making up these food concoctions. He didn’t trust them because they were marketed by big corporations and had really not looked into it more than that. But, finally when he did look more into it and got more of an academic understanding of what GMOs really do and their health benefits his Anti-GMO views started to fall apart. Another point he talks about is how he thought they would need more chemicals to take care of these GMO crops when really it would take less chemicals because the plants were meant to deal with it better. He hits beautifully on how GMOs genetics aren’t really as unnatural as everyone thinks and how this type of genome mix happens in nature and its called a gene flow. Mark Lynas states his case well and does a great job at saying why he  was wrong and exactly why he was by using facts.
