Scientists and environmental researchers began to be concerned about it. One of the most important and serious is the air pollution. Air pollution can seriously affect the personal health, ecosystems and society. Pollution results from human activities and industrial productions. In recent years, scientists reveal that the pollution will effect the whole world. For example, people burned coal in England, produced carbon dioxide, it will cause harm of the people’s health. Air pollution is the main reason that the lung cancer mortality continue raising. London is the notorious city for the air pollution.
