Heard something somewhere, forgot the source, then tried to find it online. This excerpt from Reddit comes close to it.

u/Prehistoricisms:
I see a lot of people saying that the earth is dying because of pollution, and we're killing the earth and all that stuff.
The only thing we're killing is ourselves and some currently existing species. The earth and most forms of life will continue to exist and thrive long after we're gone.
People underestimate the power of nature.
