How does the world function without humans?

So, humans go extinct in 2050 after a perfect storm of climate change, nuclear war, COVID, and our poor management of land, resources and life in general. <br><br>How do other animals treat the Earth in 2100? Do they start to change and adapt the environment or do they even care about the space left behind? <br><br>Do other primates and African animals start to curate the buildings and structures that we left behind, do the Native American Bison and Wolves start to ROAM free again? <br><br>Do other types of Americans end up in charge of the post human world? (This is purely out of string theory) do the sloths and the Koala encounter one another and the sloths become the first to colonise Australia and start to become the first and only animal to have wiped out an entire continent of animals?<br><br>Or is it the hyper intelligent rats and mice that will rebuild the world after a nuclear war that they survived by being the perfect Captain Trips rat. <br><br>Or does everything just go back to day one? Does everything go back to trees and a forest and the chimps still bang rocks together?<br><br>Or does life on earth just end??
