3 million years have passed, and buildings have almost been completely eroded to the point that even the hardiest of animals that thrive there are struggling. The only things left of them are crumbs that are scattered across watery environments such as lakes and rivers. The climate has suddenly risen to a warmish temperature with some heavy winds every now and then. Small crustaceans, especially krill, are now a rare sight causing almost every whale to go extinct with the exception of one: the Sperm Whale. With the disappearance of balleen whales and krill, plankton and large sharks have now taken over the vacant niche.
