Air pollution killed about seven million people last year, making it the world’s single biggest environmental health risk, the World Health Organisation (WHO) says. The【C1】a doubling of previous estimates, means one in eight of all global deaths were linked to polluted air. This means air pollution has【C2】poor diet, high blood pressure and tobacco smoke as the leading【C3】of preventable death worldwide. It also shows how【C4】pollution inside and outside of people’s homes could save millions of lives in future. Air pollution deaths are most【C5】from heart disease, strokes or lung disease. It is also linked to deaths from lung cancer and【C6】breathing infections. "The evidence【C7】the need for concerted action to clean up the air we all breathe," said Maria Neira, an official from WHO. "The risks from air pollution are now far greater than previously thought or understood, particularly for heart disease and strokes." Poor and middle-income countries in Southeast Asia and the Western Pacific region had the largest number of air pollution-related deaths, with 3.3 million deaths linked to indoor air pollution and 2.6 million deaths to outdoor air pollution. Indoor pollution is mostly caused by cooking【C8】coal, wood stoves. The WHO estimates that around 2.9 billion people worldwide live in homes using wood or coal as their【C9】cooking fuel. Outdoors, air is mainly polluted by transport, power generation, industrial and agricultural emissions and residential【C10】and cooking. Research suggests outdoor air pollution【C11】levels have risen significantly in some parts of the world, particularly in【C12】countries with large populations【C13】rapid industrialization. Carlos Dora, a WHO public health expert, called on governments and health【C14】to act on the evidence and【C15】policies to reduce air pollution, which【C16】would improve health and reduce humans’【C17】on climate change.
