Answer:
Pollution is a term which even kids are aware of these days. It has become so common that almost everyone acknowledges the fact that pollution is rising continuously. The term ‘pollution’ means the manifestation of any unsolicited foreign substance in something. When we talk about pollution on earth, we refer to the contamination that is happening of the natural resources by various pollutants. All this is mainly caused by human activities which harm the environment in ways more than one. Therefore, an urgent need has arisen to tackle this issue straightaway. That is to say, pollution is damaging our earth severely and we need to realize its effects and prevent this damage.
Effects of Pollution
Pollution affects the quality of life more than one can imagine. It works in mysterious ways, sometimes which cannot be seen by the naked eye. However, it is very much present in the environment. For instance, you might not be able to see the natural gases present in the air, but they are still there. Similarly, the pollutants which are messing up the air and increasing the levels of carbon dioxide is very dangerous for humans. Increased level of carbon dioxide will lead to global warming.
Further, the water is polluted in the name of industrial development, religious practices and more will cause a shortage of drinking water. Without water, human life is not possible. Moreover, the way waste is dumped on the land eventually ends up in the soil and turns toxic. If land pollution keeps on happening at this rate, we won’t have fertile soil to grow our crops on. Therefore, serious measures must be taken to reduce pollution to the core.
Types of Pollution
Air Pollution
Water Pollution
Soil Pollution
Explanation:
Pollution is when some harmful substances are added in the environment which alter its natural composition. Polluted water or garbage in the water bodies is a type of pollution. It adds germs and viruses. There are five kinds of pollution: water pollution, air pollution, noise pollution, soil pollution and thermal pollution.But two more also added that are nuclear and visual pollution.
Air can be polluted by many things. Examples include poisonous gases, sulphur dioxide, nitrogen dioxide, carbon monoxide and very small particulates. Smoke and harmful gases released by fires, industries, and thermal power plants cause air pollution. Using coal and wood as fuels for fire cause a lot of air pollution. Petroleum produces less pollution per ton, but it causes a lot of pollution since a lot of it is burned globally. Air pollution may cause health problems such as asthma or other breathing problems.

Air pollution may cause health problems such as asthma or other breathing problems.Air pollution causes global warming and acid rain. This makes it difficult for some living things to survive.
Vehicular Pollution
Vehicular PollutionIncreased vehicular traffic, haphazard urban settlements and poor roads lead to frequent traffic snarls and road accidents as also vehicular pollution, which has assumed alarming proportions. It is estimated that early 40,000 people succumb to air pollution every year in major cities of India.[source?] High-level emissions of smoke and poisonous gases cause global warming and depletion of the ozone layer, affecting the weather pattern. Summers are warmer and prolonged. Poisonous particulate matter in the air leads to respiratory and eye related problems. Even a rise in coronary cases linked to an increase in pollution levels was reported.
Water pollution is the presence of harmful materials in water, such as sewage, dissolved metal, waste from farms, factories and crude oil spilled from oil tankers. The three main substances that pollute water are nitrates from fertilizers, sewage and detergents.

The three main substances that pollute water are nitrates from fertilizers, sewage and detergents.Activities such as bathing and washing clothes near lakes, ponds or rivers add nutrients like nitrate and phosphate into the water bodies.This leads to excessive growth of algae on the surface of water. It blocks the penetration of sunlight and air, thus reducing oxygen.

Noise pollution also known as sound pollution is harmful to the brain and hearing of all animals and humans. This includes the sound of vehicles, loud speakers, airplanes, jets, train horns etc. Noise pollution can cause ear problems or even permanent deafness, especially to older people. The schools which are beside the roads suffer from noise pollution. Students cannot concentrate in their studies. Peoples admitted in hospitals which is near to the main roads also suffer. It also causes brain related problems.
Soil pollution (also known as land pollution) is caused when man-made chemicals, such as hydrocarbons, heavy metals, and solvents get into the soil. These chemicals come from industrial activities and using chemical fertilizers and from improper waste in disposal in leacky landfills. Soil pollution can cause health risks. The chemicals can produce harmful vapors, or they can contaminate water supplies underneath the polluted soil.
