We are just another species. Ecosystems and biodiversity aren’t going anywhere. The only thing that will change is their makeup. Organisms that can’t keep up with their environment die and are replaced by new ones that can.
We are another species but we operate more like a disease. We are no longer operating unchecked by the remainder of the biosphere.
> Ecosystems and biodiversity aren’t going anywhere.
If we keep up, they are. We can totally destroy the biosphere in ways that would make it, from our perspective, unrecoverable. Sure, it could recover in a few million years with other species, but that won't matter to us.

But we aren't, really. Long-term, we will be fully checked. And it will be ugly. In terms of humans, it's better that we check ourselves before nature does it because when nature course-corrects, it will probably look like a cataclysm to us.
