Final answer:
The Aral Sea has lost 90% of its surface area and 80% of its volume since 1950 due to extensive irrigation projects diverting water for agriculture in Central Asia.
Step-by-step explanation:
The body of water that has lost 90% of its surface area and 80% of its volume since 1950 is the Aral Sea.
The Aral Sea is located between Kazakhstan and Uzbekistan in Central Asia. It has experienced significant reductions in water due to extensive irrigation projects diverting water from its two main sources, the Amu Darya and Syr Darya rivers.
The diversion of water for agriculture has caused the Aral Sea to shrink dramatically, resulting in serious environmental and ecological consequences.
