For a quarter of the world's population it's not good; they are running out of water. The World Resources Institute reported that 17 countries around the world are currently under extremely high water stress, meaning they are using almost all the water they have. The cities at greatest risk are Los Angeles, Mexico City, New Delhi, Sao Paulo and Chennai
Climate change is not making things better. As rainfall becomes more erratic, the water supply becomes less reliable. At the same time, as the days grow hotter, more water evaporates from reservoirs just as demand for water increases.
The Institute is urging cities to plug leaks in the water distribution system. Recycle wastewater. Harvest rain. Clean up lakes and wetlands. Restore old wells.
