Air Pollution

Environmental changes are caused by the natural or artificial content of harmful pollutants and can cause instability, disturbance, or adverse effects on the ecosystem. Therefore, any activity that violates the original nature of the environment and leads to degradation is called pollution. Earth and its environment pose a more serious threat due to the increasing pollution of air, water, and soil. Air pollution is any physical, chemical, or biological change in the air. A certain percentage of gas is present in the atmosphere. Increasing or decreasing the composition of these gasses is detrimental to survival. This imbalance in gas composition causes an increase in global temperature. Air is one of the most vital life support systems of the Earth. Air with 78% Nitrogen, 21% Oxygen, 0.03% carbon dioxide and 1% of all other gasses support life on Earth. Various processes take place to sustain the regular percentage of gasses and their composition in general. The gaseous by-products of man-made processes such as energy production, waste incineration, transport, deforestation and agriculture, are the major air pollutants.Although air is made up of mostly Oxygen and Nitrogen, mankind, through pollution, has increased the levels of many trace gasses, and in some cases, released completely new gasses to the atmosphere. Air pollution can result in poor air quality, both in cities and in the countryside. Some air pollutants make people severly sick, causing breathing problems and increasing the likelihood of cancer. Some air pollutants are harmful to plants, animals, and the ecosystems in which they live. Statues, monuments, and buildings are being corroded by the air pollutants in the form of acid rain. It also damages crops and forests, and makes streams and lakes unsuitable for fish and other plant and animal life. Air pollution created by man-made resources is also changing the Earth’s atmosphere. It is causing the depletion of the ozone layer and letting in more harmful radiation from the Sun. The greenhouse gasses released into the atmosphere prevents heat from escaping back into space and leads to a rise in global average temperatures which later affects the average sea-level and increases the spread of tropical diseases. Air pollution occurs when large amounts of gas and tiny particles are released into the air and the ecological balance is disturbed. Each year million tons of gasses and particulate matter are emitted into the air. Primary air pollutants are pollutants, which are directly released into the air. For example, smoke, dust, ashes, radioactive compounds. However, the most gaseous air pollutant is Carbon Dioxide that is constantly being released into the air. Natural sources are volcanic eruptions, forest fires, dust storms, etc. Man-made sources include gasses released from the automobiles, industries, burning of garbage, bricks kilns, etc. Air pollution has adverse effects on human health. Breathing polluted air puts you at higher risk of asthma. Moreover, people suffer from respiratory inflammation which damages the immune system, endocrine, and reproductive systems.A high level of air pollution has been associated with higher incidents of heart problems.The toxic chemicals released into the air are greatly affecting all living beings. We can prevent pollution by utilizing raw materials, water energy, and other resources more efficiently. When less harmful substances are substituted for hazardous ones, and when toxic substances are eliminated from the production process, human health can be protected and economic wellbeing can be strengthened. The government has put restrictions on the amount of fossil fuels that can be used as well as restrictions on how much carbon dioxide and other pollutants can be emitted. Although the government is attempting to save our environment from these harmful gasses, it is not sufficient. We as a society need to keep the environment clean by controlling the pollution of air.
