2. Global warming

3.  Official opinion of the Intergovernmental Framework on Climate Change of the United Nations (IPCC - Intergovernmental Panel on Climate Change) is that " the majority of the observed from the mid-20th century increase in global average temperatures very likely due to the observed increase in anthropogenic greenhouse gas concentrations gases ". While a number of researchers disagree with some conclusions of IPCC, according to official information from the same organization the vast majority of scientists working on climate change, agree with the main conclusions.  There are also views that some scientific studies showing that anthropogenic factors are the cause of global warming are manipulated. According to them, there is evidence that scientists from Europe and North America engaged in climate research for nearly 13 years systematically falsifying presented in various reports and research papers data and conclusions about the Earth's climate over the past 2000 years in order to present the current relatively warm climate as a unique phenomenon within that period caused by human activity.

4. Air Pollution  Air pollution in European cities shortens the life of their inhabitants on average eight months, and in the most polluted areas - nearly two godini.Tova stated in the report of the European Environment Agency. In some regions, particularly in Eastern Europe, the issue of air pollution remains unresolved. The main problem, according to the report's authors, is pollution aerosol particles.  Increasing the smartnosttta and respiratory diseases lead to increased levels of tropospheric ozone pollution: according to the agency in 2010 allowed concentration of ozone in the surface layer under the rules of the World Health Organization was exceeded by 97%.  Among other major pollutants, the report identifies azotniya dioxide (NO2), flower induction of reservoirs and carcinogens benzopyran. At the same time reduce emissions of sulfur dioxide (SO2), carbon monoxide (CO), benzene and heavy metals - arsenic, cadmium, nickel and lead.

5.  Carbon monoxide is poisonous and inhaled in large quantities can cause suffocation and death. Sulfur oxide and nitrogen oxide are also poisonous gases. The carbon dioxide in larger doses difficult breathing of animals and humans. The accumulation of this gas in the atmosphere leads to a general warming (greenhouse effect) and reduce the level of the oceans.  In settlements with heavy traffic of cars and other places where fuels are combusted, the air contains large amounts of carbon dioxide, carbon monoxide and other gases are pollutants that endanger human health. Therefore, it is necessary to develop more environmentally friendly transport - electric cars, bicycles, subway.

6. Air polluted with nitrogen oxide and sulfur oxide dissolves well in small water droplets, forming clouds which, after acidification, which destroy plants corrode metals, destroy the rocks, buildings, monuments of culture. When such rain fell in rivers and lakes, killing some of the animals there.

7. How to save Nature  The less raw materials derive from nature, longer keep it clean soil, water and air.  Significantly less energy is needed to produce new products from recycled materials than extracted from natural raw materials.  Separate collection of otpadatsi will dodede to facilitate their recycling and conversion into new products.
