I don't think evolution cares about anything really. Plenty of species live pretty miserable lives, and evolution can lead them to even more miserable lives.

Evolution is not a conscious being, it is not positive nor negative, it does not try to achieve anything, and particularly not happiness for anybody.

In a similar way, we don't need to protect the environment in the sake of nature. Nature does not care, evolution does not care. Humans are the ones who care. We are the ones worrying about other animals lives, preserving species and landscape, both for romantic and practical reasons.

A super foreign virus could come tomorrow and kill all complex life on earth. Would that be a disaster? For us yes, but in general life would follow its course anyway and evolve again. Nothing has a meaning except the one we are to give.
