What would happen if humans suddenly left the earth and only the animals and our cities remained? The city of Chernobyl is an amazing, and accidental, case study in this idea. When the city was suddenly abandoned, and still remains uninhabitable, nature took over.
Plants, wildlife, and the descendants of pets that were left by the fleeing people are now free to roam the city. A unique ecosystem has grown in the wake of humans, even supporting some species that are on the brink of extinction.
This unique opportunity gives us a look at what would really happen if people suddenly left the world.
