You will learn about “Air Pollution” in this video. Cutting of trees is one of the major reasons of air pollution. Air also gets polluted due to the smoke released by many factories and industries. Burning of wood and fossil fuels is another reason of air pollution. Also, vehicles such as cars, buses, trucks etc. give out a lot of smoke that pollutes the air. Due to air pollution, human beings suffer from a number of diseases like asthma, bronchitis, cancer, skin diseases etc.
Air pollution also affects the growth of plants and causes damage to our beautiful historical monuments. As responsible citizens, it is necessary to take up some preventive measures to reduce air pollution and its effects. We must plant more trees, avoid bursting firecrackers, make more use of public transport and ensure that regular servicing of our vehicles is done. Lastly, factories and power plants should also be set up far from residential areas, which will help in reducing air pollution.

029 – Air Pollution
In this video Paul Andersen explains how air pollution is any chemicals in the atmosphere that negatively affect human health. Primary pollutants (like CO, VOCs, NOx, SO2, PM, and Lead) as well as secondary pollutants (like Ozone, nitric acid, and sulfuric acid) are included. Regulation of air pollution and technology can mediate the health threat.
