I find this kind of sentiment a little vacuous. Charitably, we might say "Much of the non-human life on Earth will be just fine without humans" but the kinds of ecological disaster that would wipe us would would take a significant chunk of other life along with it. Beyond that, what value is a floating chunk of rock except for the very fact it sustains conscious life, the only thing capable of valuing it? Humans, and other forms of life, are pretty much entirely what makes Earth worth caring about at all.

Human intelligence is the best thing ever produced on Earth

Humans will also be fine without a lot of things we have today

But humans can still do a lot of damage on our way out.

For example, the coral reefs won't be fine after humans go extinct - because there won't be any coral reefs left.

The point is no one is hurting Earth, it is hurting itself because humans are part of Earth. Unless you believe humans are aliens, you have to make peace with that fact
