Can't Get It Back

The thing is, we're already operating in those circumstances in a thousand different ways -- it's just that the risks and the damages tend to be distributed and obscured from view. They're not thrust in our face like they are in the Gulf. We don't get back the land we destroy by mining. We don't get back the species lost from deforestation and development. We don't get back islands lost to rising seas. We don't get back the coral lost to bleaching or the marine food chains lost to nitrogen runoff. Once we lose the climatic conditions in which our species evolved, we won't get them back either. (Grist)
