That pollution is bad for our health will come as a surprise to no one. That pollution kills at least 9 million people every year might. This is 16 percent of all deaths worldwide – 3 times more than AIDS, tuberculosis and malaria combined, and 15 times more than all wars and other forms of violence. Air pollution alone is responsible for 6.5 million of these 9 million deaths. Nearly 92 percent of pollution-related deaths occur in low- and middle-income countries. All this is according to the Lancet Commission on Pollution and Health, a recent report by dozens of public health and medical experts from around the world. This important report is sounding the alarm about a too-often neglected and ignored ‘silent emergency’ – or as author Rob Nixon calls it, ‘slow violence.’
