(B)
Air pollution is mainly caused by factories, power stations and cars. The chemicals in the smoke from power stations can cause much damage(毁坏). They can travel hundreds of miles in the wind before falling to the ground in the rain. And this “chemical rain” slowly destroys trees in the forests and makes fish die in the lakes. In Germany, it destroyed about 50% of the country's trees in 1986.
Time and time again there a lot of serious accidents polluted the air. In 1986, a serious accident happened at a nuclear power station in Russia. A cloud of radiation(放射线) flew across the whole Europe. It is said that 25,000 people died in Russia because of illness caused by this accident.
In 1984, there happened a serious accident at an Indian factory and a cloud of dangerous gas covered the town of Bhopal. More than 2,500 people were killed that night, and hundreds of people got injured(受伤的). A large number of the injured lost their sight.
