Cause Air Pollution and Natural Sources - 1389 Words

Causes * Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment into the atmosphere * The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth s ecosystems. Natural sources * Dust from natural sources, usually large areas of land with little or no vegetation. * Methane, emitted by the digestion of food by animals, for example cattle. * Radon gas from radioactive decay within the Earth s crust.†¦show more content†¦* This effects not only the people who breathe it but also all systems that rely on circulating air. When it is particularly heavy, the dust and grime can adversely impact machinery by clogging filters, and gears. Acid rain * Acid rain is caused when chemicals from pollutants enter the atmosphere and become bound to rain droplets. * The chemical composition of the water then changes and becomes acidic. When it falls to earth it has numerous consequences. Aside from polluting the existing water table, the acid also affects plants and trees. Acid rain can kill a forest by affecting not only the leaves and bark, but also by raising the acidity of the soil. * Acid rain affects human constructions as well, especially any item made of stone. This includes monuments and statures, but also building structures which are eaten away by the acid. Health Issues * Air pollution causes numerous health consequences for people. Like the filters in machinery and buildings, a person s lungs can become coated with the particulate matter in the pollution. * This can lead to any number of respiratory problems, depending on the levels of exposure. At the very minimum, people who suffer from asthma or respiratory issues may have more difficulty. * Long term exposure can lead to health concerns similar to long term smoking, such as cancer and emphysema.
