Researchers in Australia claim to have found a treasure trove of freshwater beneath the
ocean floor.
The findings were first revealed in the scientific journal Nature Thursday. The authors of the
study say there's "mounting evidence" freshwater could be found globally.
The study, led by a scientist from Flinders University, says these reserves were formed
hundreds of thousands of years ago. The water filtered through the ground before it ended
up being covered by ocean water.
So just how much freshwater do scientists think we have under the sea?
The International Business Times reports scientists estimate there are 120,000 cubic miles of
freshwater under the sea floor near places like Australia, North America, South Africa
and China. The study's lead author says it's more than all the underground freshwater used
since 1900.
And Gizmodo adds it's more than 20 times the amount of all the water in the five Great
Lakes.
So if we potentially have all that extra water we didn't know was there, what should we do
with it?
Scientists say if we want to use it for drinking purposes, the only ways to get it are by drilling
on land or offshore. They're careful to warn drilling can be expensive and the supply would
be non-renewable. (Via Voice of America)
But Forbes points out it might be a price some countries are willing to pay. The U.N.
projects about half the world's population could be under so-called "water stress" by
2030.
