Preventing pollution

I was walking in the busy bazaar at Trichy recently with my dad. A rashly driven bus threw heavy dust at us, A few seconds later, another lorry emanating dark smoke crossed us. A tourist bus with a blasting air horn followed the lorry and I couldn't hear what my dad was saying to me. My dad explained that this was pollution of all kinds.

It is important to keep our environment clean so that there is no hazard to our lives, the plants and animals, the water we use and the air we breathe. To keep our environment clean, we should avoid contamination of the environment with materials that interfere with our health, the quality of life or the natural functioning of the ecosystem. The contamination of the earth's environment is called "Pollution".

There are different types of pollution such as air pollution, water pollution, soil pollution, pollution due tosolid waste, pollution due to waste and noise pollution.

Pollution exists in many forms and affects many different aspects of earth's environment.

The effect of pollution may be immediate or delayed. Primary effects of pollution occur immediately after occuring of contamination, such as death of marine plants and wild life after an oil spill at sea.

Secondary effects may be delayed or may persist in the environment into the future, perhaps going unnoticed for many years.

The immediate necessity for keeping the earth's environment clean is to avoid pollution. In Industrial establishments pollution can be avoided by various methods, like chemical treatment, providing tall chimneys, taking away the emissions to isolated areas where human beings do not live. The Government has formed rules and regulations and the establishment of Industrial Unit is allowed only after getting clearance from the Pollution Control Boards to ensure that the Industry is pollution free. Various private organisations are also involved in Pollution Control.

As individuals, we can take steps to avoid pollution by growing more and more trees, keeping our living areas free from dust, waste , stagnant water and noise.
