The Aral Sea, which lies between Kazakhstan and Uzbekistan, has been getting smaller. This is because, in the 1960s, people began taking water from the two rivers that feed it, it, to to irrigate the surrounding cotton and rice fields.

As a result, the sea, which was once as large as Ireland, has reduced in size by three-quarters. One effect of the dropping water levels is that the sea has become far more salty than it used to be. Salt water is heavier than fresh water from the rivers, so it sinks to the bottom of the seabed. As the sun only heats up the top of the sea, evaporation is much quicker which means it speeds up the process of the disappearance of the lake even more
The saltiness of the water also means that most species of fish and other wildlife can't survive in it. This has had a terrible effect on the fishing industry. Thousands of people have given up their fishing livelihoods, and commercial fishing ended in 1982 Abandoned fishing boats lie on the dry land.
It's easy to see from aerial photos how the area has changed. In 1987, the continuing shrinkage split the lake into two separate bodies of water, the North Aral Sea and the South Aral Sea. In 2003, the South Aral Sea further divided into two parts.As the sea has dried up, it has left behind huge salt at plains creating massive dust storms.Incredible as it seems, the sea has rapidly been turning into a desert
Since the 1990s, engineers have built several dams to stop the water loss in the northern part of the sea. They are also spending E48m on a project to restore this part of the sea. Already more than 750 square kilometres of the former seabed are once again covered with water. However, although there is hope for restoring the northern part of the Aral, hope that the entire lake could be restored is still far off. The southern portion depends on the Amu Darya river, which is still far too heavily used for irrigation.
