Ecology is a science, which studies the relationship between all forms of life on our planet and our environment. The Earth is our common home and we must take care of it. The aim of my report is the following: to show actual environmental problems, explain how they change our life and try to find the possible ways to solve them.

Air pollution Air pollution is one of the main problems all over the world. Millions of chimneys, buses, cars, plants, factories and other industrial enterprises exhaust fumes and harmful substances into the atmosphere.

Global warming Global warming is a changing of the climate on the Earth that made life on the Earth possible.

Acid rains There are some undoubted effects of acid rains: Acid rains can increase the acidity of lakes, dams and streams and cause the death of aquatic life. Acid rain can increase the acidity of soil, water and shallow groundwater. Acid rain has been linked with the death of trees in Europe and North America. Acid rains erode buildings and monuments. Acid particles in the air are suspected of contributing to respiratory problems of people.

Water pollution There are many causes for water pollution but two general categories exist: direct and indirect contaminant sources. Direct sources include effluent outfalls from factories, refineries, waste treatment plants etc.. that emit fluids of varying quality directly into urban water supplies. Indirect sources include contaminants that enter the water supply from soils/groundwater systems and from the atmosphere via rainwater. Soils and ground waters contain the residue of human agricultural practices and improperly disposed of industrial wastes.

The main campaigning issues of this organizations are: People are beginning to realize that environmental problems are not somebody else's. They join and support various international organisations such as “Green Peace” & “Friends of the Earth” The main campaigning issues of this organizations are: The protection of all animals and plants in danger of extinction. An end to the destruction of wildlife and habitats. A program of energy conservation measures, etc.

If we want to live on the clean Earth at least we should remember about ecological culture. Ecological culture means respect of the nature not only as our home, but also as a home of millions of species of insects, animals and birds.
