I-Read the following passage and then answer the following questions:
The Aral Sea was the world's fourth-largest freshwater lake until the 1960s.People lived well from the successful fishing and local farming industries. This would have continued if the Moscow Government had not introduced a huge and sudden change. The planners suddenly decided to turn the region into a major cotton producer. The Government needed money ,and cotton sells well internationally. However ,cotton is thirsty, and the region is dry. Water was needed from the two large rivers that fed the Aral Sea. Soon ,more water was being taken from them for irrigation .Increasing amounts of farm chemicals were also being used. These started getting into the rivers ,the lake and ground water and polluting the whole environment.
