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 ?
