Humans have certainly destroyed a lot of ecosystems, like a volcanic eruption or meteor impact would. So wild nature would recover from that, reclaiming corn fields etc. But humans have also transported life around, destroying diversity of ecosystems. That's a different kind of change. I guess it's similar to continent configuration changes, like Pangaea or so.
