Desertification of Northeast China is accelerating the water system Weather and Climate

Now and north-western China has faced such problem as desertification. At the moment the threat is exposed Salt Lake IB and its ecosystem, which in four years may disappear completely. If this happens, and if time is not taken appropriate steps, we will gladly make room take Mutetar desert.

Disappearing Lake is located in the Gobi region in the north-western part of the country's rich salt basin, bordering Kazakhstan. IB literally dries up from the inside under the influence of various climatic factors. With the onset

Dam threatens the integrity of the ecosystem of the Mekong

Dam threatens the integrity of the ecosystem of the Mekong Facts

On the Mekong River in China was recently built and modern hydroelectric dam Niozhadu, fifth in the province of Yunnan. Experts believe that such construction irreparable damage to the ecosystem of the river.

River hydrological system are enough to change the previous four dams considerably slowed down the process of reproduction and movement of nutrients to the river people, changed the order of formation of river sediments. Significantly changed the Mekong Delta, the longest waterway in Southeast Asia (~ 4500 km), where more than 700 species of

China is quickly trying to save the Tibetan plateau ecosystem

China is quickly trying to save the Tibetan plateau ecosystem to save the planet

Major threat to low-lying wetland areas on the Tibetan plateau, rich moisture and vegetation is active livestock activities of local residents. The continuous growth in livestock destroys flora and water resources, thus violating the natural balance in the region, which is the source, feeding one of the most important waterways in China — the Yangtze River, the second longest in all of China.

In 2002, most suffering from the onslaught of 460,000 head of cattle a plateau area, it was decided to establish a

Ecology

29.12.10.Dmitry Smirnov. Ukrainian and Russian biologists from the results of this year's scientific expeditions to the Black Sea, have made a very sad conclusion — life in this unique body of water is on the verge of extinction. The Black Sea is no longer usual mackerel and turbot, and after 10 years the sea will die completely.

The final three Specialists Sevastopol Institute of Biology of Southern Seas spent this year five special research expeditions to see the general state of the ecological system of the Black Sea. The last time these studies were

Dying trees in the southwest worsen erosion and contribute to the reduction of water in the Colorado River

According to new research the following two successive events, drought and beetles beetle, over the past 15 years have led to the destruction of 2.5 million acres of pine and juniper odnohvoynoy in the south-western United States. The destruction of ecosystems in the region continues.

According to the researchers, the death odnohvoynoy pine causes excitement due to the fact that these trees maintain the balance of the fragile ecosystem of the region, providing food and shelter for many species of animals and prevent soil erosion. Dust from eroded hills covered with snow arrays, resulting in the absorption of solar

Elevated levels of CO2 in the atmosphere will make the African savannah to the forest

Where the grass is growing in Africa, possibly through the decades will be the forest. The increasing concentration of CO2 in the atmosphere has the advantage for the trees in the savannah.

Recent studies show that during the growing season increase in carbon dioxide in the atmosphere of Africa creates favorable conditions for the growth and increase the number of trees, if increased levels of emissions of CO2. Thus, there is a risk that the existing ecosystem due to the abrupt change in vegetation.

In the savannah grass and trees are constantly fighting for dominance. Thus, this type of

Pacific threatens void

Humanity lives in anticipation of disaster. Global warming give the world so much misery that death from a meteorite or explosion collider seems the best relief from the slow and inevitable disaster. But the problem is that people are more inclined to trust the screaming headlines and disregard serious studies.

Scientists from the U.S. Geological Survey (USGS) calculated how climate change will affect the period from 2010 to 2099 to life in the San Francisco Bay and the mouths of rivers Sacramento and San Joaquin. The conclusions drawn in the end the long and hard work, are valid

On the Antarctic Peninsula massively migrating king crabs

On the Antarctic Peninsula massively migrating king crabs that used to be held away from the cold waters. But climate change could cause a change in the whole ecosystem.

King crabs like cold sea water, but at a certain temperature, they can not take magnesium absorbed by sea water.

Therefore, up to this point they have never met in the cold waters off the coast of Antarctica. But in recent months the temperature has changed radically.

Crabs began to invade sea urchins living peacefully in the waters surrounding the Antarctic Peninsula.

Scientists are surprised, because they were

In the Black Sea, there are only three species of fish

The deterioration of the Black Sea ecosystem has greatly reduced the population of valuable fish species. Now there were only sprat, anchovy and sprat.

This was stated by the Deputy Director of the Institute of Biology of the Southern Seas (IBSS) for Science, Doctor of Biological Sciences Yuri Tokarev.

"That's what we got: sprat, sprat, anchovy. Before, there were sturgeon, turbot, bluefish, mullet. That was the main fish. Black Sea mackerel not. Anchovy and sprat are already 90% of the whole fish, which is found in the Black Sea.

The reason — overfishing and the barbaric attitude of man
