Index IntroductionTypes and Causes of PollutionEffects of Various PollutionsSolutions for PollutionsIntroductionThis essay will focus on different types of pollution, their causes, effects and ways to prevent them. Pollution can be defined as any unwanted change in the physical, chemical or biological characteristics of the natural environment. It is the result of harmful substances or energy released through human activities. Pollution comes in different forms; air, water, soil, radioactive, noise, thermal and light. Pollution is often classified as point source or nonpoint source pollution. For point sources it is easy to identify, control and monitor, while for non-point sources it is difficult to control. In 2015, pollution killed 9 million people worldwide. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"? Get an original essay Carbon dioxide, which is a greenhouse gas, is the main pollutant that is warming the Earth. Carbon dioxide can simply be produced by human and animal respiration. Additionally, it is widely considered a pollutant when associated with automobiles, airplanes, power plants, and other human activities that involve the burning of fossil fuels such as gasoline and natural gas. Over the past 150 years, such activities have pumped enough carbon dioxide into the atmosphere to raise its levels to higher levels than they have been for hundreds of thousands of years. Furthermore, there are some other pollutants such as carbon monoxide, sulfur dioxide, nitrogen oxides, lead and particulate matter which also cause pollution. Most of these gases are released from factories or through the burning of fossil fuels. These gases are poisonous and can have a negative impact on human health, the climate, agriculture or buildings. Furthermore, air pollution has always accompanied civilizations. Pollution began in prehistoric times when man created the first fires. According to a 1983 article in the journal Science, "soot" found on prehistoric cave ceilings provides ample evidence of the high levels of pollution associated with inadequate ventilation from open fires. Metal forging appears to be a key game changer in creating significant levels of air pollution outside homes. Core drilling from Greenland's glaciers indicates increased pollution associated with Greek, Roman, and Chinese metal production, but at that time the pollution was relatively small and could be managed by nature. Types and causes of pollution Air pollution is the most important and dangerous form of pollution. This pollution resembles soot, containing millions of tiny particles, floating in the air. The burning of fossil fuels is the main source of air pollution. Fossil fuels are burned using coal, natural gas and oil. This is usually done in domestic and industrial boilers and in internal vehicle engines. Elements present in fuels are oxidized when fossil fuels are burned, resulting in the formation of air pollutants. These include carbon dioxide, sulfur dioxide, nitrogen oxides and fine particulate matter. Smoke from chimneys, factories, vehicles or wood burning is essentially due to the burning of coal, which releases sulfur dioxide into the air, making it toxic. Furthermore, air pollution is caused by human activities such as open fires and burning of stalks ofdried rice. This causes the release of poisonous substances such as carbon dioxide and fine particulate matter which cause air pollution. Furthermore, air pollution can be caused by agricultural activities. Ammonia is a very common by-product of agriculture-related activities. It is one of the most dangerous gases in the atmosphere. So, the use of insecticides, pesticides and fertilizers in agriculture will also emit harmful chemicals into the air that cause air pollution. Next, water pollution is the contamination of water bodies. Water pollution usually occurs when pollutants are discharged directly or indirectly into bodies of water without adequate treatment to remove harmful compounds. First of all, it is caused by the spillage of large quantities of oil into the seas and does not dissolve in water. Furthermore, if food waste or waste in the form of plastic, paper, aluminium, rubber is thrown by every household into rivers, sea or lakes, it will lead to water pollution. Noise pollution is the propagation of noise with harmful effects on the environment. the activity of human or animal life. Noise pollution occurs when noise, which is an unpleasant sound, affects our ears and leads to psychological problems such as stress, hypertension, hearing impairment. Numerous heavy industrial vehicles, heavy machinery and above-average noise levels have caused enormous noise pollution in our environments. Road traffic, domestic noise and even traffic from railways and air have given rise to increasing noise levels. Effects of various pollutions Pollutions cause harmful effects on human health. As for air pollution, they create several heart and respiratory conditions along with cancer, among other threats to the body. This includes asthma and lung cancer which can lead to death if the condition is worse. Air pollution can cause many diseases such as chest pain, congestion, throat inflammation, cardiovascular and respiratory diseases. Several million people are known to have died due to the direct or indirect effects of air pollution. For example, according to India's News, air pollution is the fifth biggest killer in India, claiming 6.2 lakh lives a year and Delhi is among one of the five most killed. severely polluted regions of the country. Air pollution has become the fifth leading cause of death in the country, after hypertension, indoor air pollution, tobacco smoking and poor diet. There are 6.20 lakh premature deaths due to air pollution-related diseases in India. On the other hand, water pollution occurs due to water contamination. Therefore, it can cause skin-related problems, including skin irritations and rashes. Humans can suffer from these problems when drinking polluted water that contains contaminated or harmful chemicals. Likewise, noise pollution leads to hearing loss, stress, sleep disturbances, tiredness and exhaustion, annoyance and physiological losses. Besides that, pollution will cause degradation of the environment. The environment is the first victim of increased air or water pollution. The photosynthesis process of plants will be inhibited by the increasing amount of carbon dioxide in the atmosphere. This is because carbon dioxide leads to smog which can block sunlight from reaching Earth. Gases such as sulfur dioxide and nitrogen oxide can contribute to acid rain, while water pollution from oil spills can lead to the death of several wildlife species. This.
