SOIL POLLUTION: is caused by urban waste, industrial waste, biological agents, radioactive pollution.
AIR POLLUTION: is caused by smoke from vehicles, combustion of coal and petroleum, thermal power plants.
WATER POLLUTION: is caused by waste effluents, industrial effluents, surface run-off, thermal pollution, radioactive wastes, marine pollution.
There may be Noise pollution also.

Ans : There are many sources of environmental pollution in our area.

Soil Pollution: Plastic bags are thrown carelessly, lack of proper arrangement of disposing household wastes, industrial effluents and ashes etc.Excessive use of fertilizers and pesticides for cultivation.
In recent years, there has been a consistent increase in awareness of the need for a clean environment. The courts in our country have come out with a number of strong orders on environmental issues and accordingly, steps are also being taken to reduce pollution. Still, many more steps have to be implemented in this direction:
Appropriate measures need to be taken by countries and local authorities to stop the misuse or overuse of resources. For example, there are checks on the use of certain fuels such as coal, petrol, etc. in some countries. The use of renewable energy such as wind power and solar power is encouraged.
Environmental degradation can be checked by conserving land, air and water resources. For this, we have to control the pollutants at the source. Industries can utilize efficient environment-friendly processes for production and encourage recycling of their used products. That way, pollution can be controlled at the source.
The government can ensure proper enforcement of laws and norms related to environmental issues such as - use of plastic bags, disposal of all type of wastes, reduction of harmful emissions from different industries, etc. It should also punish or fine those who do not follow the laws.
