Everything on our planet is interconnected. Nature provides us with lots of products, which are indispensable to human existence and of our relationship to natural resources depends the future of all life on Earth.

The increasing globalization leads to the fact that many of the processes occurring in the nature, and its problems caused by both human activities and natural events, from the local become international. Fewer still on the Earth groups, which do not affect the dramatic environmental changes.

The most important problem of the 21st century is environmental pollution. Development of technologies to improve our quality of life has its downside: there is a pollution of the environment, harms not only by humans but also animals and plants, which eventually leads to the impoverishment of fauna and flora diversity, and even the complete disappearance of many species.

Environmental pollution does not respect borders: it is impossible to build a stone wall, or put a customs posts along the entire state border protection streams contaminated air and water masses, and other carriers of dangerous pollutants.

Nature IS NOT an object, existing separately from people; nature is us; we are an integral part of and should take care of it the best way. This is the solution of problems of environmental contamination.
