Welcome to the age of humans—the Anthropocene. Scientists, academics, public intellectuals, and policymakers have been using this term to describe a new geological epoch marking an unprecedented era of human impact on the natural environment. Beginning with the Industrial Revolution in the late 18th century, carrying through the development and testing of nuclear weapons, and peaking in recent decades with rapid global warming and the catastrophic depletion of the Earth’s biodiversity, the Anthropocene is often framed as an existential threat to the survival of the human species. Like some of the great environmental catastrophes of the past—such as the mass extinction that wiped out the dinosaurs 65 million years ago—the footprint of human activity will be present in the geological record for millions of years to come. Or so the reasoning goes.
