Extinctions did happen before humans arrived. But now extinctions are occuring at a tremendous rate, because people are not careful about what habitat they destroy or how they move species around. Ecologically, this is not really different from any other introduction of a non-native predator - and that type of introduction has caused the rapid extinction, extirpation, or marginalization of native species time and time again.

I mean, seriously, stuff like this happened before humans came around. It will continue after we've evolved into something else. Can’t stop evolution, baby!
