We have a word for the conscious slaughter of a racial or ethnic group: genocide. And one for the destruction of the environment: ecocide. But we don’t have a word for the conscious act of destroying the planet we live on. A possibility might be “terracide” from the Latin word for earth. The truth is, whatever we call them, it’s time to talk bluntly about the terrarists of our world. It has the right ring, given its similarity to the commonplace danger word of our era: terrorist.
