More than one billion people – one sixth of the world’s population – are without access to safe water supply. At any given moment, about half of the world’s poor are suffering from waterborne diseases, of which over 6,000 – mainly children – die each day by consuming unsafe drinking water. The aptly-named LifeStraw is an invention that could become one of the greatest life-savers in history. It is a 25 cm long, 29 mm diameter, plastic pipe filter and purchased singly, costs around US2.00. [via] Link.
