Obtaining Fresh water from icebergs

Tweet

Glaciers are a possible source of fresh water that has been overlookd until recently.Three-quarters of the Earth's fresh water supply is still ried up in glacial ice, a reservoir of untapped fresh water so immense that it could sustain all the rivers of the world for 1,000 years. Floating on the oceans every year are 7,659 trillion metric tons of ice encased in 10000 icebergs that break away from the polar ice caps,more than nenety percent of them from Antarctica.
