In a talk (link includes transcript) to the Oxford Farming Conference, Lynas apologizes for and reputes his high-profile previous position on genetically modified food.
He explained the underlying reason for his shift: he began adding science to his climate change work, denigrating those relying on poor quality reports. At some point, he was challenged to begin reading high level reports on GM.
He doesn’t repute organic farming (his parents, who are organic farmers, approved his speech!), but he does point out that organic techniques lead to greater land use, and thus lower biodiversity.
His talk is worth listening to. What do you think?
