The water loss exceeded the limit of natural water level variation that has occurred in the past. Additionally, there are abnormally high levels of blood diseases, cancer, asthma, and heart disease, all of which can be linked to the ecological disaster. The process has caused major concern for many in the agricultural community but has moreover led to a widespread concern for much of the developing world. The heat capacity is reduced; therefore it can warm up and cool off faster than before. Another way is to use more efficient types of irrigation. The above mentioned diseases and illnesses are proven to have risen drastically over the last forty years; some of them are now said to be at epidemic proportions. Farmers were able to grow several kinds of subtropical crops, including cotton, rice, and tobacco, in the warm climate of Central Asia.
At least they had the North Aral sea to attempt to recover one of the thing that they did is the Kazakh government planned to build Dike Kokaral, a concrete dam separating the two different parts of the Aral Sea. Disappearing the Aral Sea effect on unemployment. The environment of the country is becoming worse and worse-there is not enough water and living things are dying. However, the pesticides did not just shrink the water; it affected the human-beings' health problems as well. In 1987, because of the continuing loss of water, the sea then divided into two water bodies; the smaller sea in the north and the larger one in the south. The Aral Sea is situated among the deserts of central Asia, in south western Kazakhstan and north western Uzbekistan, near the Caspian Sea.
Until the present century, fluctuations in its surface level were at least 20 m and possibly more than 40 m. The fresh water from these two rivers held the Aral's water and salt levels in perfect balance. The former Soviet Union diverted the two rivers that fed the Aral Sea, to make water available to the surrounding cotton fields and other crop farming regions in the desert like area. This paper gives a broad overview of the policies that have resulted in dying of the forth-largest inland body of water. Unbelievably, the Aral Sea once was one of the biggest in-land seas on earth.
As a result of throwing pesticides into the sea, the great catastrophe in the area of the Aral Sea, strongly affected its residents. The largest problem, generated by the desiccation of Aral and by the scarcity of fresh water, is salting of biosphere. Over the years it was dramatically decreased to 80 % of its size since 1960. Other rivers feeding the basin are the Tedzhen and Murgabi Rivers and the Karakum canal, as well as shallow rivers from Kopet Dag and western Tien-Shan. This is a dangerous process for an arid region because mountain glaciers of Central Asia are the only ancient reserves of fresh water and the main place for condensation of atmospheric moisture in the region.
The two sea turtles who are accidentally caught more often are the loggerhead sea turtle and the leatherback sea turtle. The Aral is an inland salt-water sea with no outlet. Due to the retreating of water many ancient remains were disappeared. It concentrates on the policies and approaches of the international organizations towards the problem, describes examples of the projects and presents a conclusion on effectiveness of such policies. Now it is the eighth largest inland body of water on account o.
From 1961 to 1970, the Aral's sea level fell at an average of 20 cm a year; in the 1970s, the average rate nearly tripled to 50—60 cm per year, and by the 1980s it continued to drop, now with a mean of 80—90 cm each year. It is no exaggeration to say that the case of the Aral Sea is one of the greatest environmental catastrophes ever recorded. Today the Aral Sea is biologically dead and has shrunk by approximately 75-80% in volume and 50-60% in area. Although less publicized, desertification is an issue that requires international cooperation as the victims of drought,… 1919 Words 8 Pages Heather Field Introduction Located in the Northern region of North Sea, heather field have been producing oil since 1978 to 2001. Human impacts included big withdrawals for irrigation from the Amu Dar'ya and diversions of this river west into lower lying channels because of the destruction of dikes, dams, and irrigation systems during wars.
Not only do the tides advance and retreat in their eternal rhythms, but the level of the sea itself is never at rest. Therefore, it could be said that human activity has been the main cause of the shrinking of the Aral Sea. One of the most ambitious plans for the future within the region, involves the building of a massive dam to separate for ever, the two parts that the sea have now split into. The water has gone but the salt levels or salinity has remained virtually the same, resulting in the salinity level actually rising within the seas because of the lower volume of water and the saline residues being left to settle upon the old and now arid sea bed. In school textbooks these data are still given in present time, no less than on geographical maps Aral is depicted as the enormous blue mirror on the Earth. Today no fish are caught in this sea.
To The south conquered northern part of vietnam, the west as far as Aral Sea and a high amount of Tibet under their control. Soon the introduction of new fish left the sea barren of all fish, mentioning before closing down the fishing industry of the Aral Sea. The place where I feel most relaxed is a place where I am happy; a place where I can get away from life. Large dams were built across both rivers, and an 850-mile central canal with a far-reaching system of smaller canals was created. All through the long history of Earth it has been an area of unrest where waves have broken heavily against the land, where the tides have pressed forward over the continents, receded, and then returned. The annual dust storms spread the salt on the vast territory of Eurasia.
