In it, he mentioned that food containing genetically modified organisms (GMOs) could pose environmental risks:
Genetically engineering food is controversial, as it should be. If you’re asking me, we should stop introducing genes from one species into another, while at the same time taking full advantage of our ability to understand the genome of any organism — plant, animal, or fungus — in order to produce the healthiest, most sustainable food system possible. Here’s why: Although we can know exactly what happens to any organism we modify, we just can’t quite know what will happen to other species in that modified organism’s ecosystem. For me this is a big deal, though some other investigators don’t seem to find it as troubling.
But in a video filmed after his recent appearance on Bill Maher‘s show, Nye explained that he has studied the issue more since writing that chapter. He’s spent time with scientists who are experts in this area. And he admits his fears were nothing to be concerned about:
