Global Warming: Air Pollution
Air pollution is the presence of one or more contaminants in such a quality and for such a time ass is injurious or can be injurious, to humans, animals or plants. It is the contamination of air by the discharge of harmful substances. This can cause health issues and can damage to the environment. Air pollution also contributes in the major issue which boosts Global Warming which is, Greenhouse Gases. Greenhouse gases includes all the harmful gases which are both natural and man-made, these gases thin up the ozone layer, which in return accelerates the threat and pace of Global Warming.
Industrialization has led to the air getting more and more contaminated over the years. Vehicles increase in the pollution and urbanization are some of the major factors responsible for air pollution. Air pollution results from various causes, not all which are not within human control. Dust storms in desert areas smoke from forest fires, grass fires and particulate pollution of the air. The source of pollution is affected everywhere.
Below are some of the major air pollutants and their causes:
- Carbon monoxide (CO): Is a type of gas which has neither smell and color, it’s produced by the incomplete burning of carbon-based fuels such as petrol, diesel and wood. It is also generated from the combustion of natural and synthetic products. It is not good for human health and definitely not a substitute of oxygen. If we breathe it we would become slow, confused and sleepy.
- Chlorofluorocarbons (CFC): These gases are released from air conditioning systems and other products which releases gas. When this harmful gas is released into the air, CFC rises to the stratosphere where they combine with other gases reducing the ozone layer that shield the earth from dangerous ultraviolet rays of the sun.
- Nitrogen oxide (Nox): Nitrogen oxide causes smog and acid rain. It is generated by burning fuels which include petrol, diesel and other materials extracted from the Earth’s surface. This deadly gas can cause children to have a respiratory illness during winters.
- Chemical Pollution: There are different sources of chemical pollution which includes, sewage, and industrial waste and other forms of wastes, accidents and spills at sea etc.
- Sulphur dioxide: This gas is created with the help of burning coal, mostly in thermal power plants. It contributes in making smog and acid rain, this gas leads to lung diseases as well.
