Many years ago people lived in harmony with the
environment because industry was not much developed. Now the situation is quite
different. People all over the world cannot ignore the problem of the
protection of the environment because of modem industry and the need for
energy. Newspapers and magazines write a lot about water pollution, air
pollution and land pollution. There are some laws and decisions on this
important question. There are state organisations and international conventions
which pay much attention to this problem.
Many parts of the world are crowded now, much of our
waste, especially waste from factories, electric power stations, the chemical
industry and heavy industry are very dangerous. Fish dies in the lakes, rivers
and seas, forest trees die too.
The problem of radiation has also become a very
important problem because it is very dangerous for health of people. There is a
science, named ecology, which study the relation between people and their
environment. But each of us also must do everything possible to keep our
environment clean for ourselves and for the next generations.
