The World Health Organization says air pollution is now the world's single-largest environmental health risk. A new report from the WHO says nearly eight million people died in 2012 because of air pollution. That is more than twice as many as the number in 2008. Air pollution is an international problem. The World Health Organization says one in eight people die from air pollution, from both inside buildings and outside. It says new information shows air pollution is partly to blame for people dying at an early age from h eart disease. It says other causes of death include cancer and or long-term diseases of the lungs and breathing passages. The WHO report says most deaths from air pollution take place in low- and middle-income countries in Southeast Asia and the western Pacific Ocean. About half of the world's population lives in those countries. Many people who live there use open fires  or simple equipment to cook food and heat their homes. Health officials say 4.2 million people died at an early age in 2012 because of the burning of coal and biomass fuels -- such as wood, crop waste and animal wastes. They say 3.7 million others died in cities and rural areas because of outside air pollution. Carlos Dora says countries must work together to reduce air pollution because what happens in one country can affect lives in another country. Dr. Dora says at one time, air pollution was worse in developed countries than in developing ones. But he notes developed countries -- especially Britain and the United States -- have taken steps to greatly reduce air pollution during the past 10 years. He says measures that help cut air pollution can be costly. But he says they may save money in the long term by lowering health care costs. 64.
