Can you think of any cases in which non-human nature needs human intervention?

I'm trying to figure out if non-human nature depends on people at all?

Not specific cases, but I do know that animal extinctions have happened since long before man arrived on the scene, so I don't like the guilt that some groups try to impress on mankind. We can't prevent extinctions, but we can prolong it for a short time, which is a good thing.Can you think of any cases in which non-human nature needs human intervention?
Some breeds of dogs need help in reproducing. Granted they were bred that way. Natural nature needs no nurturing.
