Vast freshwater reserves have been discovered under the ocean floor which scientists believe could sustain future generations.
Australian researchers claim to have found 500,000 cubic kilometres (120,000 cubic miles) of freshwater buried beneath the seabed on continental shelves off Australia, China, North America and South Africa.
The deposits were formed over hundreds of thousands of years in the past, when the sea level was much lower and areas now under the ocean were exposed to rainfall which was absorbed into the underlying water table.
When the polar icecaps started melting about 20,000 years ago these coastlines disappeared under water, but their aquifers remain intact - protected by layers of clay and sediment.
Post said the deposits were comparable with the bore basins currently relied upon by much of the world for drinking water and would cost much less than seawater to desalinate.
Drilling for the water would be expensive, and Post said great care would have to be taken not to contaminate the aquifers.
