Pollution is a difficult word to define and one of the greatest problems the world faces today. Many people don’t know where it exactly started. Pollution is considered to be anything that makes the earth dirty and unhealthy. Air, land, and water are agitated by this problem. There are several types of pollution, and they may come from different sources, but all of them generate the same results [1]. “Air pollution can be defined as the presence of toxic chemicals or compounds in the air (including those of biological origin), which contaminate it and have a fatal effect on the health of living beings” [1]. Air pollution has a great impact on the planet and humans’ health; however, a number of initiatives can help to reduce this impact. Air

There are various natural processes that contribute to pollution in the air, which include natural events like tornadoes, eruption of volcanoes, dust, wildfire, animal and vegetation [1]. Debris can be stirred up due to tornadoes and volcanoes, leading to widespread air pollution. Erosion of soils and rock can result in release of different types of toxins in the air, like radon, which is a major cause of lung cancer in the world [4]. Particulate matters are released in the air because of wood fire that can get lodged in the respiratory system of humans and animals, resulting in irritation to issues. Existing health conditions like asthma can also be aggravated because of these natural causes of air pollution. However, the major causes of air pollution are the activities that are undertaken by human beings, which include burning of waste, fossil fuels, smoke originating from vehicles and industries, gases and agricultural activities [5]. The biggest human source resulting in air pollution is the emissions from industrial establishments, power plants and vehicles [2]. “Air conditioners and vehicles emanate carbon dioxide, which is one of the major air pollutants in urban areas” [7]. Carbon monoxide is a colourless, poisonous gas that is formed when fossil fuels like natural gas, petroleum and coal burn. Furthermore, all manufacturing plants, industries and automobiles emit toxic pollutants like carbon dioxide, nitrogen oxide and sulphur dioxide among others, contributing to generation of acid rain [3]. Air pollution is also present in rural areas, as dust flies in the field at the time of farming and toxic gases are emitted by tractors [2]. Furthermore, the ammonia-based fertilisers and insecticides used by farmers are harmful air pollutants, as unwanted chemicals get released in atmosphere because of them. In some countries, dead animals are skinned and the
