Lakes of the WORLD in the FACE of ENVIRONMENTAL DISASTER
The lake is very vulnerable, so they are difficult to maintain. But their condition is largely ignored, even if it gets worse
More than half of lakes and reservoirs on Earth threatened ecological catastrophe. But the world pays little attention. This will be examined at the International conference on monitoring ecological status of lakes.
The Commission of experts at a conference in Japan stated that lakes are polluted with agricultural fertilizers, waste industry and human activity, and increasing demand for water contributes to the drying up of lakes.
Some lakes are already in a catastrophic state. For example, the Aral Sea located in Central Asia between Uzbekistan and Kazakhstan. After the direction of rivers flowing into it was changed to 60 years for agricultural purposes, the lake area has decreased in two times.
Experts say that other large lakes are under threat of destruction. This is lake Victoria in Africa, lake Okeechobee in Florida and lake Baikal in Russia.
Lake in the UK, for example, suffer from congestion caused by tourism, while risk and ecological systems. Although lakes in industrialized and developing countries are in danger, only rich countries can find the resources to save them. This is the opinion of experts.
“The lake is very vulnerable, so they are difficult to maintain. But their condition is largely ignored, even if it gets worse,” says Hideaki ODA (Oda Hideaki), the Secretary-General of the Third world water Forum (World Water Forum), which will be held in Japan next year. “Until now, the policy mainly focused on rivers, tidal basins and oceans, avoiding conversations about the lakes and the potential danger to mankind: their destruction”.
In preparation for the forum is expected to hold a series of conferences. This week the conference has set up a Research Institute lake Biwa, the biggest lake in Japan. The Commission of experts indicates that lakes and reservoirs contain about 90% of fresh water in the world. They are under threat, as population growth increases demand for water. Presumably, by 2025 the world population will increase by another 2 billion people.
“Natural lakes, especially large ones, have huge economic, environmental and cultural value. At least, they are directly related billion people, which, thus, livelihood and drinking water, said Masahisa Nakamura(Masahisa Nakamura), the Director of the Research Institute Lake Biwa. – Lakes are sources of trade, transport, recreation, tourism, food and energy. They are also a habitat for many species of plants and animals.”
According to the Commission, are under threat: lake Victoria – the largest lake in Africa, around the coast to merge it waste, it also disappear the fish. Lake Baikal in Siberia, the deepest lake in the world containing one fifth of the world’s fresh water suffers from pollution from industrial plants located along the coast.
Most of the lakes are suffering from eutrofication process, which yields an overabundance of nutrients that leads to rapid growth of water plants and the suppression of other forms of life, and excess sludge formation.
The second reason is the danger – the poisoning of lakes by toxic industrial waste. Emptying human waste into the lake and use the lake water also is a significant problem.
Research has shown that from 1990 to 1995 the consumption of water from rivers and lakes has increased six-fold. These figures exceed the population growth rate twice.
