There are a lot of problems facing people on the planet Earth nowadays. The most urgent problem is an ecological one.

Interrelations between man and the biosphere are complex. Man like any other living organism depends for his life on what the biosphere provides: water, oxygen, food, shelter. On the other hand all sorts of human activity make the environment unhealthy. The main problems are: air pollution, water pollution, acid rains, safety of nuclear and hydraulic power stations, radioactive and other poisonous materials, disposal of waste and others. Let’s consider some of them.

Car engines burn gasoline, factories burn fuels. All these gases pollute the air. The biggest problem is ozone, formed from hydrocarbons and nitrogen oxides. Ozone can age our lungs, making us more susceptible to dangerous diseases, including cancer. Some factories produce liquid wastes and dump them into ri­vers and lakes. This problem includes oil pollution which causes great damage to coasts and wild life.

Acid rains damage forests, poison rivers and lakes, make them
lifeless.

Safety of nuclear and hydraulic power stations is another acute problem. Public anxiety has grown particularly after the Chernobyl disaster. Radioactive and other poisonous materials present health and safety problems.

As the population of large cities continues to grow, the pro­blem of Industrial and communal waste disposal has become urgent. In more than a hundred towns and cities the concentration of harmful substances in the air and water is over 10 times the admissible level.

In recent years people have become more sensitive towards the environment. Still more public organizations and unofficial movements have been established. In 1987 a "Green Peace"' public commission was set up. Its main goal is to combine the pe­ople's efforts in the struggle for peace and nature conservation.

Russia is cooperating in this field with the USA, Canada, Finland, and Norway. The other way out of ecological problems is to turn te­chnology to the construction of healthy environment. We must leave our planet better for future generations than it is now.
