C'mon, that's the kind of broad-brush pap that doesn't make any sense...
We started "f'ing with the gene pool" thousands of years ago when we started breeding animals (Mendel only figured out what we were doing, and really put it to work. He considered himself an environmentalist and nature-lover.)
Humans have been messing with genes, transplanting strains of things around the world (the Europeans owe us for saving their wine industry more than 100 years ago!), etc. long before now. I think it just comes down to a failure to communicate with consumers, give them choices, and not box ourselves into a "can't go back" situation, as Monsanto has done with bt and roundup-ready seeds.
