Our earth is surrounded by a thick layer of air. The air is a part of the earth and we live in an ocean of air. The air is a mixture of some gases like nitrogen (78%), oxygen (21%), carbon dioxide (0.03%) and other inert gases. It also contains water vapor. When the air is polluted by harmful contaminants, it is called air pollution.
Presently the air is being polluted in many ways. Several greenhouse gases are found in air. Burning of fossil fuels for electricity generation and the release of hazardous pollution from vehicles are the prime sources of air pollutants.
Air pollution leads to difficulty in breathing. Any decrease in the percentage of oxygen in the air disrupts the respiratory system of living organisms. People suffer from diseases such as asthma because of air pollution. Even the health of animals gets negatively effected because of air pollution.
The presence of contaminated substances negatively affect the ecosystem. Air is the medium for locomotion of birds and other flying animals. It also helps in the dispersal of seeds, fruits, pollen and spores for propagation and reproduction of certain plants.
The pollutants present in the wind influences the environment and have an effect on weather and climate. Besides, it also causes soil erosion.
The solution to the problem of Air Pollution lies in putting seal on its causes. Fossil fuels such as coal, petroleum, diesel, kerosene, etc., should be burnt cautiously. More emphasis should be given on using alternate sources of energy that emit less pollutants.
Indoor air pollution can be tackled to some extent by using an air purifier. People can use masks to mitigate the harms from outdoor air pollution. More trees can be planted and new forests can be developed.
