Wherever they are, people need water to survive. Not only is the human body 60 percent water, the resource is also essential for producing food, clothing, and computers, moving our waste stream, and keeping us and the environment healthy.
Unfortunately, humans have proved to be inefficient water users. (The average hamburger takes 2,400 liters, or 630 gallons, of water to produce, and many water-intensive crops, such as cotton, are grown in arid regions.)
According to the United Nations, water use has grown at more than twice the rate of population increase in the last century. By 2025, an estimated 1.8 billion people will live in areas plagued by water scarcity, with two-thirds of the world's population living in water-stressed regions as a result of use, growth, and climate change.
The challenge we face now is how to effectively conserve, manage, and distribute the water we have. National Geographic's Freshwater Web site encourages you to explore the local stories and global trends defining the world's water crisis. Learn where freshwater resources exist; how they are used; and how climate, technology, policy, and people play a role in both creating obstacles and finding solutions. Peruse the site to learn how you can make a difference by reducing your water footprint and getting involved with local and global water conservation and advocacy efforts.
