Not A Drop To Drink (National Geographic Investigates)

Global warming is a hot-button topic and has far-reaching consequences. Two of those consequences may be increasing desertification and drought around the globe. Researchers are racing to come up with ways to conserve water. Clean drinking water is already scarce in some parts of the world, and disputes over water rights create potential for conflict. Water, or the lack of it, impacts farming and world food supplies. Can science come up with answers to the problems affecting our most precious resource? It is National Geographic's mission to explore the world and all that's in it and to bring scientific discoveries and knowledge to the widest array of people possible. National Geographic Investigates introduces young people to cutting-edge techniques of scientific investigation, the most recent research, and the way current discoveries benefit every part of the natural world.
