Students today will be nearing retirement in 2050 when one writer here predicts “Billions of People Will Run Out of Fresh Water by 2050.” Other chapters include “One-Third of the World is Already Facing Water Scarcity,” “The Water Crisis Also Affects Rich Countries,” “Global Warming Will Exacerbate Water Problems,” “The Scarcity of Water Could Lead to War,” “Technological Solutions Alone May Not Solve the Water Crisis,” “Better Water Management Is the Key to Solving the Water Crisis” and “Worldwide Efforts Are Necessary to Prevent a World Water Crisis.” It would be difficult to dispute the notion that a water crisis looms, and it will take individual and group efforts to solve this problem. Our students will need to learn how to save fresh water, and they can’t start too soon to recognize the challenge and begin to take steps to meet it.
