Extinction and extirpation play an integral role in the environment. As paleontologist Grant Zazula once said,

Extinction is essential for evolution to be possible. Environmental change works like that too. It might be detrimental to one critter, like warming climates and forest expansion was for woolly mammoths, but it created a great opportunity for giant ground sloths to multiply and expand.

The problem lies with the direct causation that human activities incur on different organisms. The planet is more resilient than we might think, though this doesn’t mean we should abuse it.
