Welcome to the Anthropocene. It’s a new geological era, so take a good look around. A single species is in charge of the planet, altering its features almost at will. And what more natural than to name this new era after that top-of-the-heap anthropoid, ourselves? The term was coined in 2000 by the Nobel Prize-winning Dutch atmospheric scientist Paul Crutzen to describe the past two centuries of our planet’s evolution. “I was at a conference where someone said something about the Holocene, the long period of relatively stable climate since the end of the last ice age,” he told me later. “I suddenly thought that this was wrong. The world has changed too much. So I said: ‘No, we are in the Anthropocene.’ I just made up the word on the spur of the moment. Everyone was shocked. But it seems to have stuck.”
