More Water, Less Waste: Improving Global Sanitation and Freshwater Access

Around the world, temperatures are rising and sources of freshwater are becoming increasingly unpredictable. Two and a half billion people already lack access to basic sanitation, and nearly one billion people lack access to safe drinking water. Adding to the problem, global warming is expected to lead to more floods and more droughts, both of which reduce the availability of safe, clean freshwater for drinking, sanitation, irrigation and other basic needs. Fortunately, there are technologies such as waterless toilets and rainwater harvesting that can be deployed immediately -- and cost-effectively -- to improve sanitation, protect existing supplies of freshwater, and create new sources of safe water.
