Lab: Who Pays the Price When a Sea Disappears? Introduction: The Aral Sea is slowly decreasing in water volume. Its surface area shrank by 60%, and its volume by 80%. This affects special groups of people and including fish. People that get necessities from the Aral Sea will have a hard time to look for another source. In a way, it affects the economy because of the lack of supply of products. The purpose of this lab is to inform and persuade a panel about the importance of this ecological crisis. Background Information: The Aral Sea is located between Uzbekistan and Kazakhstan and is the largest inland body of salty reservoirs in the world. Its "Aral Sea" origins from the Turkic word "aral" which literally means island. Its name reflects the fact that it is a vast basin that lies as an island among waterless deserts. The Aral Sea was once the world's fourth largest inland sea. By 1987, about 60 per cent of the Aral Sea's volume had been lost, its depth had declined by 14 m (45 feet), and its salt concentration had doubled, killing the commercial fishing trade. Wind storms became toxic, carrying fine grains of clay and salts deposited on exposed sea floor. Life expectancies in the districts near the sea are significantly lower than in the surrounding areas. As a result, it is now a quarter of the size it was 50 years ago. Hypothesis: If we give out statistics, present diagrams and present images as reference to this problem, then we can successfully persuade and bring proper attention to this crisis. Procedure:
