More than two hundred years ago, the term “environmental pollution” was quite strange to

people. they lived healthily, drank pure water, and breathed fresh air. Nowadays, the situation is

quite different. People all over the world are worried about things that are happening to the

environment. Actually, it is man that is destroying the surroundings with many kinds of wastes.

Everybody knows that motorbikes and cars emit dangerous gases that cause poisonous air and

cancer, but no one wants to travel on foot or by bicycle. Manufactures know that wastes from

factories make water and soil polluted, but they do not want to spend a lot of their money on treating

the wastes safely. Scattering rubbish is bad for our health, but no one wants to spend time burying

it. Is it worth talking a lot about pollution ?
