Humans are more important as animals and yes that is self preservation speaking. Frankly I would happily kill of a few thousand endangered species to save the lives of a few humans. While this may not seem palatable, and in retrospect will not be. We have to do what is right for the species we belong to.
I get that everyone thinks that we should put our own species first which in some cases is the right thing to do but to kill endangered species especially on such a level is wrong. If you kill all the animals in a species then they will be extinct! You will never see one ever again.
On top of that animals have the right to live like humans have the right and by saying that humans are more important is selfish and WRONG!
