Our current impacts are significantly different from what they were four hundred years ago. They will probably be even more different in another few centuries. Assuming we do not wipe ourselves out, our eventual impact will be very different from our current impact. Maybe we will even reverse many things, and a millennium is just a blip in geological time.
