The world's water crisis is still in full force.
Approximately 750 million people around the world still lack access to safe, drinkable water -- 90% of whom live in sub-Saharan Africa and Asia, according to the World Health Organization's latest statistics.
In addition, a new report from the United Nations warns that global water resources may only meet 60% of the world’s water demands by 2030.
But various entrepreneurs, innovators and organizations are working hard to create devices with the potential to change that number. From the LifeStraw, which allows users to sip water through a simple, straw-shaped filtration tool, to the LUV Water system, which purifies water using weight and gravity, there are various ideas that offer hope in this dire situation.
In honor of World Water Day, we're highlighting five inventions that use innovative science and technology to help increase global access to clean water.
