What would happen if humans disappeared from the face of the planet right now? What would happen to our infrastructure, the wild animals… our legacy?
This is the topic Alan Weisman tackles in his speculative non-fiction book, The World Without Us (which I’m considering adding to my reading list purely out of curiosity).
1 Year: Worldwide, a billion annually doomed birds would live when radio and communication tower warning lights cease blinking and high tension wires grow cold. Animals would begin to return to the sites of nuclear reactors, which would have all melted down or burned. Human head- and body-lice would grow extinct.
35,000 â€“ 100,000 Years: Lead deposited during the smokestack era would finally be cleansed from the soil.
7,200,000 Years: Toxic manmade chemical compounds, such as PCBs and dioxins, would likely also still be intact, although mostly buried.
