Pollution is the process of making soil, water, air or other parts of the environment dirty.

Today i will tell you about some types of pollution like soil,air and water pollution.With the rise of concrete buildings and roads, one part of the Earth that we rarely see is the soil. It has many different names, such as dirt, mud, and ground. However, it is definitely very important to us. The plants that feed us grow in soil, and keeping it healthy is essential to maintaining a beautiful planet.However, like all other forms of nature, the soil also suffers from pollution. Soil pollution is a common thing these days, and it happens due to the presence of man-made elements.The presence of harmful toxic compounds in extreme quantities in the air results in air pollution. The primary sources of air pollution are harmful gases like sulfur dioxide, carbon dioxide, carbon monoxide, nitrous oxide, nitrogen dioxide, and other suspended particles.

Air pollution is usually caused by burning fossil fuels like petroleum, and coal-burning of wood and cow dung cakes in homes, factories, vehicles, and power plants. Among all other continents globally, India is the country with the most polluted cities. Lucknow, Kanpur, New Delhi are a few among them because of excessive use of fossil fuels by vehicles and other industrial units.

Water pollution
The contamination of water bodies, such as lakes, rivers, oceans, underground water and seas by harmful substances is water pollution. The leading cause of water pollution is sewage, industrial wastes, pesticides and fertilisers from farming.

Polluted water becomes unfit for drinking, bathing, washing, and irrigation. Garbage dumping can also leak out pollutants into underground water.

The major water pollutants are lead, mercury, fertilisers and pesticide compounds. The sewage and industrial wastes from tanning factories are the primary sources of the Ganga river’s pollution.
Air pollution is the contamination of air due to the presence of substances called pollutants in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials.[1] It is also the contamination of the indoor or outdoor environment either by chemical, physical, or biological agents that alters the natural features of the atmosphere.[1] There are many different types of air pollutants, such as gases (including ammonia, carbon monoxide, sulfur dioxide, nitrous oxides, methane and chlorofluorocarbons), particulates (both organic and inorganic), and biological molecules. Air pollution can cause diseases, allergies, and even death to humans; it can also cause harm to other living organisms such as animals and crops, and may damage the natural environment (for example, climate change, ozone depletion or habitat degradation) or built environment (for example, acid rain).[2] Air pollution can be caused by both human activities[3] and natural phenomena.[4]
