Malaria was almost wiped out before DDT was banned, and it raged back, killing millions. And all this because Rachel Carson wrote a book blaming all chemicals for nearly every problem in the world, hiding the fact she had cancer which she blamed on industrial development.
She generated hysteria and many things not actually toxic were labeled such - and now we have malaria plus Zika and West Nile virus we can't control.
There's hysteria on GMOs, but no one complains about how we turned wolves into chihuauas, teosente into corn, the radical changes people already wrought - or the billions we could feed on less land if there's better use of genetic engineering.
If we can feed more people on less land, much more of the planet can go wild. Demand a return to organic farming, and you'll have to rip up a lot of forest and prairie to feed everyone.
