Environmental problems have become one of the most urgent problems of modern society. More and more people suffer from air and water pollution. Nature also suffers from land and nuclear pollution. The pollution of air and the world’s ocean, destruction of the ozone layer is the result of man’s careless interaction with nature

3 The main ecological problems
Increasing number of cars in the streets Factory waste Millions of cut down trees Destroyed habitats of animal Contaminated rivers and seas

4 The main ecological problems
Factories, while producing industry and food for human consumption, contribute to the pollution of the environment. The waste that results from factory production often ends up in the soil. Waste also contaminates the air, contributing to smog, poor air quality and acid rain.

5 The main ecological problems
Forests cover about 30% of the earth's surface, but this percentage is decreasing because annually harvested about million hectares of forests of which 5-6 million saplings. All this is done to provide the raw material in industry

6 The main ecological problems
Nearly 1300 species of plants are endangered. Endangered animals are species, which are under the treat of extinction. They can disappear fast from the face of the Earth.

7 The main ecological problems
Water pollution is one of the most serious environmental problems. It occurs when water is contaminated by such substances as human and animal wastes, toxic industrial chemicals, agricultural residues, oil and heat.

8 How to help the environmental
Fortunately, there are many ways to suspend these problems. If everybody starts caring about the planet we live on, many environmental problems can be solved. For example, if we start recycling paper and cardboard, we can save lots of trees. If we start using public transport more than private cars, we can have less air pollution. Local governments can also help to prevent some problems, if they forbid logging companies to destroy the forests, or stop factories from polluting water. The most important thing is, of course, to start acting immediately, otherwise we might have to face many global disasters
