Environmental problems
environmental problem air baikal
Environmental problems have become exceptionally acute in the modern world, and environmental protection has become a vital necessity for all people.
Our planet is in serious danger. One of the most important environmental problems in the world today is the shortage of clean water. Industrial pollution has made many sources of water undrinkable. Rivers, lakes and even seas have become poisonous. Thousands of fish die every year as a result of the illegal dumping of waste in rivers by factories all over the world.
Lake Baikal is one of the worlds' largest and most beautiful lakes. It contains a rich variety of fish and plants, including 1,300 rare species that do not exist anywhere else in the world. However, they are being killed by massive industrial waste, which some factories still pour into the lake every day. A few years ago people thought that the supply of clean water was unlimited. Now clean water is scarceю. We must protect the clean water that remains for the sake of our children and grandchildren.
Air pollution is another important problem. In hundreds of cities and towns the concentration of harmful substances in the air is over ten times the admissible level. Every day a huge number of plants and factories emit lots of harmful substances into the atmosphere of big cities. Pollution from factories and cars poison the air we breathe, and is the main reason for the greenhouse effect and acid rain.
Acid rain can damage life in lakes and rivers and destroy forests. The greenhouse effect may also have disastrous consequences for our planet. The world's temperature is going up and the climate is changing. I think we should try and use alternative energy, such as solar energy and wind energy, and design plants and cars that run on electricity, a much cleaner fuel than petrol.
One of the most alarming environmental problems is depletion of the ozone layer, which protects the Earth from the dangerous ultraviolet rays of the sun. Because of the ozone holes causing skin cancer and other serious diseases. Many scientists think that these ozone holes are the result of air pollution.
In my opinion, the most urgent ecological problem today is the environmental safety of nuclear power stations. Nuclear pollution can't be seen, but its effects can be terrible. We all know how tragic the consequences of the Chernobyl disaster are. Nuclear waste also endangers people's lives. People all over the world protest against nuclear tests and nuclear weapons. If we do not take any action, the possibility of a global nuclear disaster is very real.
Today environmental issues are much spoken and written about on TV, radio, and in the newspapers. If people want to survive, they must do their best to solve these problems. Fortunately, it's not too late to save our planet. We understand that our environment is not just our home town, but the whole earth. Governments should take measures that will help improve the environment.
We should take care of birds and animals. We can help to plant trees and create parks for endangered species. We can clean rivers and canals and create footpaths. But first of all we must change people's attitude towards the environment.
