Which of the following has/have shrunk immensely/dried up in the recent past due to human activities?

1. Aral Sea
2. Black Sea
3. Lake Baikal

Select the correct answer using the codes given below:

Justification: S1: The Aral Sea is a saline lake located in Central Asia that was once the world’s fourth largest salt lake. In the 1960s the Aral Sea, which was the drainage basin for Kyrgyzstan, Turkmenistan, Tajikistan, Uzbekistan, Pakistan, Afghanistan, and Kazakhstan, began to shrink as the Soviet Union began to divert water for agricultural purposes. The Aral Sea, which was once 26,300 square miles in size had decreased in size by 2007 to only 10% of its original area.

Lake Baikal hasn’t shrunk immensely yet. Certainly its water is shrinking. But, it’s not ‘immense’ like Aral Sea. If one has to go for two options, the intensity of shrinkage should be either equal or comparable. Case of Aral Sea is extreme and Lake Baikal’s present condition, which is better, is no comparison to Aral Sea’s fate.
