Ape genocide
Ape genocide is very nasty and has horrible consequences. Like slavery it spreads diseases, e.g. eating chimps can give you ebola, and someone may have eaten the Green Monkey that brought HIV to the human race.
The UN appointed Jane Goodall a goodwill ambassador specifically to get rid of it. Gus Kouwenhoven profits from it as he logs their rainforests and hires hunters to shoot chimps to eat.
