200 Words – Essay on Causes of Pollution for Kids & Students in Very Easy Words
There are many human activities that cause pollution of the environment. Human activities such as industrialization, urbanization, deforestation have increased as a result of world wide development and population growth.
Each activity described affects the environment in its own way. For example, industrialization causes contamination of air and water bodies, as a lot of toxic byproducts in both gaseous and liquid forms are produced by production industries. In the absence of proper management, these pollutants are released into the environment, resulting in pollution of air and water bodies.
Similarly, transport vehicles use fossil fuels, which produce harmful gases such as CO (carbon monoxide), CO2 (carbon dioxide) when burnt. These gases are again mixed with atmospheric air, causing air pollution.
Human activities such as deforestation do not directly contribute to pollution; Yet it reduces the Earth’s ability to deal with pollution. Forests act as natural buffer zones and air filters. They absorb noise pollution and exchange CO2 with too much O2 (oxygen). When more forests are cut, it increases atmospheric concentrations of these toxic gases, which adversely affects human health as well as the health of flora and fauna.

When an unwanted substance enters an otherwise natural and pure environment, this phenomenon is called pollution. There are many factors that cause pollution and almost all of them are human induced. Natural pollutants causing potential harm to the environment are negligible.
Due to pollution
Below we have discussed some of the main factors of pollution of the environment. All factors involve human activities and humans need expansion, exploration and development.
1. Industrialization
Man’s quest for economic development has created clusters of industries all over the world. These manufacturing industries emit toxic fumes as bioproducts, which are emitted into the environment.
Industrial emissions may also contain toxic gases, chemicals, and solids. Due to the lack of effective policies, these substances are emitted into the environment independently by industries, resulting in environmental pollution.
2. Use of fossil fuels
Transport vehicles use fossil fuels as their main fuel. The burning of fossil fuels produces gases such as carbon dioxide (CO2. and carbon monoxide (CO. as byproducts. The introduction of more vehicles on the road means more of these toxic gases in the atmosphere.
At the same time fossil fuel making industries produce toxic gaseous compounds which are very harmful to the environment.
3. Littering
Littering is another most common cause for environmental pollution. Common household waste or urban waste, to be more specific, litter occurs which, due to the lack of effective waste management methods, reaches our natural environment.
Urban waste contains toxic compounds such as polyethylene, glass, lead, garbage etc. This waste reaches our soil and water bodies, resulting in their pollution.
4. Agricultural activities
Agricultural activities such as the use of chemical fertilizers contaminate the soil resulting in pollution. Modern fertilizers use chemicals that can temporarily increase crop yield but are harmful to the environment in the long run.
These chemicals mix with the soil and later flow into our water bodies or ground water resources as runoff.
The conclusion
Pollution is a vast subject that includes many triggering factors and many implications. There is a need to look into every factor causing pollution and take necessary preventive measures.

The causes of pollution are not only limited to traditional pollutants such as carbon dioxide (CO2. and carbon monoxide (CO., which are emitted from the burning of fossil fuels by transport vehicles, but also many other factors responsible for environmental pollution.
What are the causes of increasing pollution
Below we have discussed some unconventional causes / causes of pollution.
1. Heavy Machinery and Equipment
I am expanding this world, new constructions are happening every minute; Transport vehicles and huge jet liners are moving men and machinery from one place to another within a few hours. These heavy machinery used for construction work and airplanes are the main sources of noise pollution. Although noise pollution is not considered as serious as air and water pollution, it also has its own impact on human health and the environment.
2. excessive use of light
Excess use of unwanted light in areas of urban settlements causes light pollution. Lights shine in areas where it is not needed, often interfering with each other as well. In addition, there are many lights pointing to a particular location, which require less light. The presence of excess light over a particular area is called light pollution. Although, light is one of the most neglected causes of pollution, it still has a very degrading effect on the environment and its inhabitants.
3. Urban runoff
Urban settlements are a major cause of pollution in and around human settlements. Urban runoff contains many types of solid and liquid pollutants, often toxic in nature. It also contains harmful chemicals from agricultural areas using chemical fertilizers. Urban settlement is the main cause of air, water and soil pollution in and around the urban settlement.
4. Excess use of plastic
Excess use of plastics in the form of bags and other consumables is also one of the main causes of environmental pollution. Plastic is non biodegradable and as it has lived in the environment for centuries. Thin plastic bags break into small pieces and reach the soil and water bodies, resulting in increased pollution.
The conclusion
Pollution is caused by many human induced activities. There is a need to formulate an effective policy to prevent the harmful effects of pollution on the environment. This can only be achieved by strong will and determination for government agencies and people.

500 Words – Essay on Causes of Pollution for Kids & Students in Very Easy Words
As we all know that pollution refers to the contamination of our natural environment or contamination by pollutants, which is mainly caused by human activity. There are some traditional causes of pollution like fossil fuel use by vehicles and non-traditional reasons like volcanoes, forest areas etc.
Types of causes of pollution
The causes of pollution can be classified into two categories – human induced pollution and natural pollution. Below we will briefly discuss two types of pollution.
Human induced pollution
1. vehicle exhaust fumes
Fumes emitted by vehicle exhaust are the main cause of air pollution in an urban area. Vehicles use petrol or diesel, which produces carbon monoxide (CO. upon combustion. CO is toxic in nature and also causes irreparable damage to the environment and human health.
2. Power plants
In addition to vehicles that use fossil fuels, power plants also use large amounts of fossil fuels, resulting in environmental damage. During the entire process of fossil fuels burning in the power plant, sulfur dioxide (SO2. is produced, which combines with the water vapor present in the atmosphere and causes a phenomenon called acid rain. Acid rain is very harmful to the flora and fauna of the environment.
3. Industrial Exhaust
Industrial exhaust is a major cause of environmental pollution. Industries emit harmful gases into the environment. Some of them also release liquid chemical pollutants and other dangerous solid compounds into nearby water bodies. It causes great harm to and contaminates the natural water resource, also threatens the life of flora and fauna and aquatic plants and animals.
4. Construction activities
Constant construction activities are a major cause of air pollution in urban areas. Very small particles of dust are added to the air in activities resulting from grinding, foundation excavation, sump construction, transportation. These particles are called Particulate Matter (PM. and are simply suspended in air, for hours, sometimes even days. It is dangerous to breathe air in excess of the prescribed amount of particulate matter and can cause serious respiratory diseases.
Natural causes of pollution
There are also some natural causes of pollution, which cause great harm to the environment. Although, they are not consistent in appearance, yet, they cause considerable damage to the environment.
Some of the natural causes of environmental pollution are volcanoes, forest fires, dust storms. During volcanic eruptions and forest fires, large quantities of toxic gases are released, causing damage to the environment.
The conclusion
There is a need to immediately limit the effects of pollution as it is destroying the environment with every passing minute. Not only is pollution polluting our natural resources, but it also threatens the existence of life on earth.
It is the collective responsibility of all to take necessary action to prevent any damage to the environment. This can be achieved by reducing waste and introducing new and effective waste disposal and management techniques.
