Affects of Daily Air Pollution on Our Lives There are so many issues in today’s society that one can simply over look the drastic need to help control air pollution in our daily lives. Pollution can be found everywhere- in our air‚ soil‚ water‚ sound and even the light. Although most air pollutants are from natural resources‚ a vast majority of environmental concerns are man-made.

Air pollution is a combination of gases and chemicals in the air that we breathe. A majority of air pollution is caused by humans through emissions from cars‚ planes‚ ships‚ trucks‚ power plants‚ and factories; although some of it may be created by nature in the form of wildfire smoke and volcanic eruptions (education.nationalgeographic.com‚ 2015). By breathing toxic air‚ air pollutants are given the chance to travel far into the lungs‚ resulting in severe damages to the respiratory system. Air

Air pollution and its health impacts on three cities Air pollution has a significant impact on human health. It can cause death by compromising the respiratory and cardiorascular system‚ or by its toxic carcinogenic effects. Transport is the greatest source of air pollutions‚ owing to increased numbers of cars in the city. Moreover‚ manufacturing and factories are another reason for air pollution. Results from the government not having suitable policy on air pollution are becoming more and more

provided funding for research of air pollution. The Clean Air Act of 1963 was the 1st designed to control air pollution. The 1955 Air Pollution Control Act was the 1st U.S. federal law that focused on air pollution. The Clean Air Act accomplished this by setting up a federal program within the U.S. Public Health Service & allowing research into techniques for monitoring & controlling air pollution. It was 1st amended in 1965‚ by the Motor Vehicle Air Pollution‚ which authorized the federal government

HISTORY Long before the Industrial Revolution began‚ air pollution has proved to be a significant issue for the wellbeing of people across the globe. For many‚ the cause of their respiratory‚ circulatory‚ and cardiovascular diseases‚ and even the reasons for thousands of deaths‚ began at home.
