Water stress is basically the difficulty in obtaining sources of fresh water during a period of time. It involves water deficit and water crisis. it affects 2.8 billion people in the world. We asked Mohammed Sinan, a university professor, if its possible to invent a substitute resource that can replace water in the world. "Impossible", he said.
"We still have a small quantity of clean water in this world, but we have a chance to save our lives and other creatures lives and it’s by finding a way to purify sea water and make it more useful".
