Environmental pollution kills 1.7 million children under the age of five every year worldwide.This is according to the World Health Organization（WHO）.The WHO warns that child deaths will increase greatly if pollution continues to worsen.
   Dr Margaret Chan，the WHO Director-General，said in a press release statement，"A polluted environment is a deadly one-particularly for young children，whose developing organs and immune systems，and smaller bodies and airways，make them easily get hurt by dirty air and water."The WHO also says reducing environmental risks can prevent deaths like pneumonia（肺炎） among children aged one month to five years.This means providing access to safe water and sanitation（衛(wèi)生設備），limiting exposure to dangerous chemicals，and improving waste management.
   However，of all the environmental pollutants，air pollution is being called the most dangerous.The WHO estimates that air pollution is responsible for about 6.5 million early deaths every year.That number includes nearly 600，000 deaths of children under age five.WHO environment and health chief Maria Neira says one of the most important ways to reduce air pollution is to produce cleaner fuels for cooking and heating."Almost half of the world population is using dirty fuels for cooking，heating，and lighting at home.And，this is affecting very much mothers who are staying and cooking at home，but the children who are
around mothers—they are exposed as well."She says early exposure to harmful pollutants can lead to increased risk of asthma（哮喘），heart disease，stroke and cancer later in life.
   Cleaning up how the world cooks，heats and lights homes and other buildings is a big-picture goal.The WHO is advising government departments and industries such as construction and the health sector to work together to clean up their environment，ensuring that children grow up in a clean environment.
