"We’re turning everything on the planet into food for humans so we’re cutting down the rainforests, displacing all of the animals, and we’re doing all this to feed humans... ...

If this population keeps growing, we’ll just keep devouring the planet, and I don’t think it’s going to stand for that very long."
