ENVIRONMENTAL POLLUTION

Air,water,soil,trees and all our environment make up our condition.

When the normal relationanong  these elements of  nature are distrurbed the ecological balance is toppled and it is called environmental Pollution.

Water Pollution:Water is essential for all sports of life.But Polluted water is very harmful;yet water pollution is common. Man Pollutes it by throwing waste into it.Farmers use fertilizers and insectides.These Chemicals get mixed with flood and rain water and reach rivers,canals and ponds. As a result,the water of these places becomes Polluted.The waste Products of mills and factories are thrown into nearby rivers and canals.This leads to the Pollution of water of these rivers and canals. Steamers,motor launces and even sail boats Pollute water by throwing oil,food waste and human wastes.Most unsanitary latrines and drains in Bangladesh pollute river and canal water.But clean water is necessary for good health,and it is necessary to prevent pollution in order to keep water clean.

Air Pollution:
Air becomes polluted in many ways.Smoke pollutes air,and by breathing polluted air man gets sick.The sickness that the smoke from factories causes cannot be cured.Man makes fires for different purposes.These fires emit a lot of smoke,which pollutes air.Coal oil burnt  by railway engines,powerhouses and mills and factories create smoke. Many chemicals used in mills and factories create smoke,Petrol and diesel oil,when burnt,creat smoke.And all kinds of smoke pollute air.However,serious air pollution occurs in big cities and big industrial areas.

Sound Pollution:
Sound is essential elements of our environment.It becomes pollute in many ways.We have noise from motor vehicles,mills and factories,airoplanes,domestic appliances,radios,cassette  players,televisions and so on.Specialists say that  it effects our hearing,our  nerves,our ability to work efficiently and our general health.We should do something about this form of pollution which is getting worse every day.The authority should pass strict laws to take effective steps against the  sound pollution.People must be made award of the dangers of the sound pollution too.

Brown haze HANGING OVER urban areas is the most commonplace and evident type of air contamination. However, there are various types of contamination—some unmistakable, some imperceptible—that add to an Earth-wide temperature boost. By and large any substance that individuals bring into the air that effectsly affects living things and nature is viewed as air contamination.

The Leading Pollutant:

 Carbon dioxide, an ozone harming substance, is the fundamental contamination that is warming Earth. Despite the fact that living things emanate carbon dioxide when they inhale, carbon dioxide is broadly viewed as a poison when related with vehicles, planes, control plants, and other human exercises that include the consuming of petroleum derivatives, for example, fuel and gaseous petrol. In the previous 150 years, such exercises have siphoned enough carbon dioxide into the environment to raise its dimensions higher than they have been for a huge number of years.

How to Control Pollution?

 The following steps may be taken to control pollution:

***People should be made aware.

***Our forests should be proteted and mor trees should be                planted.

***Waste must not be dumped into water.

***Motor vehicles should be banned.

***Plastic bags should be banned.

***We must prevent using chemicals.

So,we  should be friendly with the environment. Government alone  can`t do anything if we do not play our own roles.
