Environmental Pollution

Environmental pollution is caused due to over-use of natural resources, presence of a large number of people and livestock in congested areas, use of agro-chemicals, setting up of factories, running of automobiles, burning of fuel, etc.
A change in the environment due to pollution also affects the ecological balance. Environmental pollution is caused both ins rural and urban areas. Pollution can cause sickness and discomfort. It also affects the productivity of natural resources, such as land, water, forests and livestock. We can prevent environmental pollution if we understand its causes.
Pollution in Rural Areas
In rural areas, pollution takes place around the houses, colonies and public places.

Pollution around Houses:
In rural areas, most of the house are poorly ventilated because of small windows and low roofs. Keeping livestock inside the house is an old practice. In the absence of toilets, villagers use open fields. As the families grow, the number of houses increase and the colonies become congested. Thus, pollution occurs in many ways.
