Is this what the world's coming to? Amanda Leigh Haag, Nature Reports: Climate Change With climate change placing increasing pressure on environmental resources, it is now being viewed as a threat to national security. --- History is littered with lessons from once-budding civilizations that crashed from their peak of prosperity. From the Anasazi of the southwestern United States to the Mayans of Mesoamerica1 and the ancient dynasties of eastern China2, environmental change has sounded the death knell throughout time for once-thriving civilizations already stressed by factors including high population growth, overexploitation of resources and excessive reliance on external trade. In many cases, severe drought or extreme cold has been enough to push societies to the brink of civil unrest, mass migration and warfare. Is this what the world's coming to? But it's not necessary to look that far back into history to see how environmental change can result in conflict and the breakdown of society. In a study published in a special issue of the journal Political Geography[3], titled Climate Change-induced Migration and Violent Conflict, Rafael Reuveny, a political scientist at Indiana University, found that, of 38 cases of migration directly attributable to climate change during the twentieth century, half led to conflict, some of which were violent.
