Humans are a threat to our own species and to many others, but the planet will survive us. In fact, it may only take life on Earth a few million years to recover from us. Life has bounced back from far more serious shocks. Two hundred and fifty million years ago, during the Permian extinction, ocean surface waters likely reached 104 degrees Fahrenheit, or 40 degrees Celsius. Ninety-five percent of Earth’s species went extinct, and for five million years afterward, Earth was a “dead zone” with little expansion of life.

Sixty-six million years ago, an asteroid impact caused a dust cloud so huge that darkness may have pervaded Earth for two years, virtually stopping photosynthesis and leading to the extinction of 75 percent of land animals. Measured against these disasters, we’re just not that important. When Earth is done with us, it’ll be like, “Well, that Human Pox wasn’t great, but at least I didn’t get Large Asteroid Syndrome.”

The hard part, evolutionarily, was getting from prokaryotic cells to eukaryotic ones, and then getting from single-celled organisms to multicellular ones. Earth is around 4.5 billion years old, a timescale I simply cannot get my head around. Instead, let’s imagine Earth’s history as a calendar year, with the formation of Earth being January 1, and today being December 31 at 11:59 PM. The first life on Earth emerges around February 25. Photosynthetic organisms first appear in late March. Multicellular life doesn’t appear until August or September. The first dinosaurs like eoraptor show up about 230 million years ago, or December 13 in our calendar year. The meteor impact that heralds the end of the dinosaurs happens around December 26. Homo sapiens aren’t part of the story until December 31 at 11:48 PM.*

Put another way: It took Earth about three billion years to go from single-celled life to multicellular life. It took less than seventy million years to go from Tyrannosaurus rex to humans who can read and write and dig up fossils and approximate the timeline of life and worry about its ending. Unless we somehow manage to eliminate all multicellular life from the planet, Earth won’t have to start all the way over, and it will be okay—at least until the oceans evaporate and the planet gets consumed by the sun.

But we’ll be gone by then, as will our collective and collected memory. I think part of what scares me about the end of humanity is the end of those memories. I believe that if a tree falls in the woods and no one is there to hear it, it does make a sound. But if no one is around to play Billie Holiday records, those songs really won’t make a sound anymore. We’ve caused a lot of suffering, but we’ve also caused much else.

I know the world will survive us—and in some ways it will be more alive. More birdsong. More creatures roaming around. More plants cracking through our pavement, rewilding the planet we terraformed. I imagine coyotes sleeping in the ruins of the homes we built. I imagine our plastic still washing up on beaches hundreds of years after the last of us is gone. I imagine moths, having no artificial lights toward which to fly, turning back to the moon.
