When things go extinct without human presence, it’s a morally neutral event. It’s just something that happens. No one cries for the trilobites.

When you say the source of earth’s problems are because of humans, I believe you’re right but not for the reason you think. Earth doesn’t have problems. Earth simply abides. Humans on earth, they have belief systems that consider certain changes to the planet problems. In that sense humans are the cause of the problems. Without humans to care about it, it’s just a change, not a problem.
