Asteroids, supervolcanoes, nuclear war, climate change, engineered viruses, artificial intelligence, and even aliens — the end may be closer than you think. For the next two weeks, OneZero will be featuring essays drawn from editor Bryan Walsh’s forthcoming book End Times: A Brief Guide to the End of the World, which hits shelves on August 27 and is available for pre-order now, as well as pieces by other experts in the burgeoning field of existential risk. But we’re not helpless. It’s up to us to postpone the apocalypse.

IfIf you suspect the world is falling apart, you’re not alone. In a 2012 poll by Reuters covering more than 20 countries, 15% of respondents predicted that the world would end in their lifetimes. A 2015 survey of Americans, British, Canadians, and Australians found that a majority rated the risk of our way of life ending within the next one hundred years at 50% or greater, while a quarter believed humanity had a better than even chance of being wiped out altogether over that time frame. In 2018, a UN scientific panel reported that the world had just 12 years to sharply reduce carbon emissions or risk a global catastrophe. Young people seriously question whether they should have children, fearing that bringing new human beings into a world on the brink of total catastrophe would be a moral obscenity.

What’s ironic is that this existential panic unfolds against the backdrop of a world that — for most of humanity — is better than it has ever been. In 2018, for the first time in history, more than half of the world’s population qualified as “middle class” or “rich.” Infant mortality has fallen by more than half over the past 25 years. Even as weapons have grown far more lethal, the global death rate from conflict is less than it was six hundred years ago, when we still largely fought with swords and spears. And if numbers like that seem too dry, ask yourself this question: Would I have preferred to be born 50 years ago, not long after a global war killed more than 60 million people? One hundred years ago, before the age of antibiotics, when a simple infection could be end your life? One thousand years…
