        The Disappearing Aral Sea

        Human activity has reshaped the face of Earth in dramatic, and often unintended, ways. In this visualization adapted from NASA, satellite images show how water diverted from the Aral Sea for agriculture has caused the land-locked lake to shrink considerably over a short period of time. In just 30 years, this lake has lost more than 60 percent of its water. Barring change, the Aral Sea may disappear entirely by 2020.
