More than two hundred years ago, the term “Environmental pollution” was very 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. Manufacturers 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.
