We are faced with three common problems that are warming the Earth, the sea and ocean pollution along with desertification. The average temperature of the Earth hotter now close to 40 degrees C compared with the temperature in the nearest ice age, about 13 000 years ago. But in the last 100 years, the average temperature increase the Earth's surface is about 0, 6-0, 7 degrees Celsius and expected to increase by 1, 4-5, 8 degrees Celsius in the next 100 years. Global warming have a profound impact on the environment and society. One inevitable consequence of the increase in the Earth's temperature is rising sea levels, increased intensity of hurricanes and other extreme weather events, uzon layer depletion, changes in agriculture , and degrade uxy in the ocean. the speed of global warming in the XXI century, faster than the adaptation of species, so some species being extinct. Seas and oceans are becoming night call for help because of severe pollution. Annually, about 50 million tons of solid waste dumped into the sea, including land, sand, waste, construction waste, radioactive material ... Besides, oil leaks, oil spills from ships usually accounts 50% of oil pollution at sea. through speaking following figure, we can see the consequences of Suo somewhat infections: - 1 000 000 seabirds, marine mammals and turtles 100. 000 marine caught or killed by suffocation by plastic garbage. - 30-50% CO2 emissions from the combustion of fossil fuels is absorbed the ocean, the temperature change will affect the ability to CO2 absorbed by phytoplankton and then to affect ecosystems. - 60% of coral reefs are threatened by the pollution. - 60% of the Pacific coast and 35% seaboard Atlantic is eroding at a rate of 1 m / yr If humans are spot sea view is an enormous fortune junk can contain all sorts of waste, the ocean environment will also ruined more seriously, not just as current status. Each year, approaching the Sahara desert to the south at a speed of 45 km / year. Plateau of Madagascar - which is considered the treasure of biodiversity but now 7% of the land is barren land and bare hills. In Kazakhstan, since 1980, 50% of farmland has been abandoned as too harsh in the desert promised progress. Biodiversity is in decline, the land becomes unsuitable for agriculture infertile are two photos mainly effects of desertification processes. This situation is threatening the lives of nearly 1 billion people on Earth. Africa can only feed 25% of the population in 2025 if the rate of desertification on the continent promise to continue as at present.
