Once a year, the Earth has its day. Nowadays, the Earth Day is celebrated in many countries. The first Earth Day was held on April, 22, 1970 when millions of people gathered in parks and paraded down city streets throughout the United States. They wanted to emphasize one very important thing: taking care of the Earth, preserving its beauty is everybody's business.

It's true that some very general problems of present society are: different ways of destruction of nature as consequences of human development. They affect living, economy, working and environment. They are changing cities of all sizes as well as rural areas. Recent results from science show that success is only possible when an integrated approach is undertaken. For this goal, citizens, companies, politicians and governments should work together. Thus, coalitions between economy and environmentalists must be very close in order to overcome economic and ecological problems.

The necessity of such approach became evident in the XX century.

Many species of flora and fauna have been written down into the «Red Book» of Nature as they are on the brink of extinction. People's industrial activity changed the life to the better but at the expense of the natural resources and nature itself.

Now people are aware of the ecological problems such as the change of climate, acid rains, deforestation of the Earth, depletion of the ozone layer and many others.
