Hundreds of 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?
