The WWF, built to do things under a green cape that otherwise could not happen. Like claiming rain forest is unused land and allowing to plant oiltrees on there. The WWF was build to make things like that possible. And they have the most money of all these organisations. Because those who profit from it are rich already.

And trophy hunting is important. Most of these reservates only survive with the money coming from that. Take that away and the only thing you get are poachers.

Might be that it is not nice but most of the animals killed there would have to be killed anyway because they need to be regulated in order to not destroy the environment.
