Opinion: Is it ALWAYS needed for humans to restore an ecosystem? (no correct answer)
Yes, humans have altered the ecosystem, so they have the ethical responsibility to restore it to what it once was.
Yes, the health of the ecosystem is better for the earth, and therefore, better for humans.
No, there are some circumstances where nature can do a better job at restoring back to health than humans can, and in some cases, humans just end up making it worse by trying to fix it.
No, humans don't need to worry about restoring the ecosystem. It will take care of itself.
I don't really know... but I will think about this more, as I know that this will be a question asked of me later.
