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:
"… There’s a chapter in [the book] which I’m gonna revise. I spent some time on it, and I’m very excited… I went to Monsanto and I spent a lot of time with the scientists there, and I have revised my outlook, and I’m very excited about telling the world. When you’re in love, you want to tell the world!"
