Water is essential for life. But it has to be in very good condition, otherwise it can transmit diseases. Indeed, in the Aims for the Millennium, approved in 2000, one of the targets to reach by 2015 was to 'reduce by half the number of people lacking access to safe drinking water'. Fortunately, an American NGO called 'Potters for Peace' has found an easy way to reach it: the 'Ceramic Water Filter', a device that makes water safe to drink, a system which filters contaminated water, for very little cost, and which can be made with very simple technology.
