Humanity is at a crossroads. We have ample evidence that Earth is headed for disaster, and for the first time in history we have the ability to prevent that disaster from wiping us out. Whether the disaster is caused by humans or by nature, it is inevitable. But our doom is not. How can I say that with so much certainty? Because the world has been almost completely destroyed at least half a dozen times already in Earth’s 4.5 billion-year history, and every single time there have been survivors. Earth has been shattered by asteroid impacts, choked by extreme greenhouse gases, locked up in ice, bombarded with cosmic radiation, and ripped open by megavolcanoes so enormous they are almost unimaginable. Each of these disasters caused mass extinctions, during which more than 75 per cent of the species on Earth died out. And yet every single time, living creatures carried on, adapting to survive under the harshest of conditions.
