Clean water graphene breakthrough could allow millions to drink filtered seawater

‘As drought conditions continue to spread across the globe, from the 2015 drought in California that swept over 90 percent of the state to South American countries like Brazil, and even nations in Africa — it is clear that water is an ever-increasingly precious resource. Even though the Earth is approximately 70 percent water, the overwhelming majority of that water is saline and ocean-based, which means it’s undrinkable for humans. Just 2.5 percent of the earth’s water is freshwater, and even then — only 1 percent of that is readily accessible, as most of that is trapped in glaciers and snowfields.
As National Geographic explains, only about .007 percent of all the Earth’s water is available to its massive human population. This, of course, is a tremendous problem. But a new salvation could be on the horizon. Scientists have developed a special graphene sieve that stands to change the game when it comes to the world’s water crisis.’
