From the source: https://www.greenpeace.org/usa/sustainable-agriculture/issues/gmos/ https://www.greenpeace.org/usa/sustainable-agriculture/issue... A summary of their concerns would be: * GMO tend to be “pesticide resistant” (eg roundup-ready) and more pesticide is bad for humans and the environment * GMO has not been proven to be safe for human consumption * GMO turns agriculture into IP which threatens the sovereignty of farmers So yes, the IP concern is a big one for anti-GM campaigners, but I’d not say it’s the primary one. (As an aside, I think the pesticide concerns are quite strong, but not all GM crops encourage pesticide use, so I’d rather restrict pesticides than GM. I don’t find the human safety concerns convincing. And the IP concerns are quite compelling to me, but again I think these could be better fixed elsewhere in the system, for example by state funded GM research or IP law reform, rather than banning GMOs.)
