Why do some species evolve while others go extinct?

thats just how the cookie crumbles.

Explanation:

While some species evolve, due to a thriving enviroment and cross breeding, the world is dying. Millions of habitats have been destroyed, causing some animals to not survive in the wild. Like pandas, when their homes were being destroyed, they starved. When they starved, they didn't reproduce. On and on and on.
