There are many sources of environmental pollution in our area.
→ Air Pollution: By vehicles, industrial gases disposed through chimneys, smokes from red brick Bhattas.
→ Water Pollution: Various chemical discharges and other liquid effluents from some industries like tanneries, aluminium etc. Because of dry latrines and inefficient discharge of house wastes and sewerage into the river.
→ Soil Pollution: Due to the throwing of plastic bags here and there, lack of proper arrangement of disposing household wastes, industrial effluents and ashes etc.

In the 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 the environmental issues and accordingly steps are also being taken to reduce pollutions. But still many more things have to be done in this direction:
→ Appropriate measures need to be taken by countries and local authorities of the world to stop the misuse or overuse of resources.
→ Environmental degradation can be checked by conserving land, air and water resources. For this we have to control the pollutants at the source.
→ By proper enforcement of laws and norms related to environmental issues such as – use of plastic bags, disposal of all type of wastes, harmful emissions from different industries, etc.
