An overview of the important causes of air pollution

Researchers and environmental scientists use particular methods for obtaining data on air pollution that ultimately provide information on what changes are occurring and what those changes mean for our planet and its inhabitants. These methods are Air Quality Monitoring, source monitoring and ambient air monitoring. This is how we know air pollution has a serious impact on us and the environment. Main sources of air pollution are automobiles, power plants, pesticides, and industrial factories. Air pollution from these sources have been found to be a part of the current major predicament of climate change that the world is facing as well as some health problems that it causes. Studies have shown air pollution contributes to greenhouse gas levels, rising seas, extreme weather, and health effects caused directly from pollution. The results of data and research done have led to increased awareness that brought about change in laws, regulations, technology, and societal standards that have lowered the effects of air pollution such as the creation of the Environmental Protection Agency, Clean Air Act, introduction of fuel efficient and electric cars, and the development of a society with a “go green” conservation attitude.
