They lived healthily, drank pure water, and breathed fresh air. In those days, industry was not well-developed. Nowadays, the situation is quite different. The world today is faced with many major threats. The most dangerous threat of all is war, and after the threat of war is pollution. 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 from the devices that make human lives more comfortable and convenient. Everybody knows that cars emit dangerous gases that cause poisonous air and cancer, but no one wants to travel on foot or by bicycles. 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?
