Here’s hoping the human species likes its own company, because at the rate Earth is going, we might be the only ones we’ve got left.

Nobody can say with certainty how many species there are on Earth, but the number runs well into the millions. Many of them, of course, are on the order of bacteria and spores. The other ones, the ones we can see and count and interact with—to say nothing of the ones we like—are far fewer. And, according to a new and alarming series of papers in Science, their numbers are falling fast, thanks mostly to us.
