Theme: What would happen if every human disappeared?
We all know people live everywhere on Earth. In a few minutes, we will imagine what happened if everyone disappeared on Earth? Many electronic systems, factories, and anything controlled by humans will be damaged in just three days. A few weeks later most emergency generators shut down. After the first catastrophic month changes come more gradually within skyscrapers buckle and tumble down. Within 75 years most houses supporting beams have rotted and sagged and the resulting collapsed heap is home to local lizards. After several million years humanity's legacies live on carved in unyielding granite America's Mount Rushmore survive for 7.2 million years. Humanity has not always been here and we will not be here forever but investigating the world without us. Perhaps we can learn more about the world we live in now.
