The world may be running out of water, but there are a few things you can do to help plug the leaks, so to speak.
To coincide with World Water Day, National Geographic fellow Sandra Postel has assembled a list of 10 ways you can save fresh water -- which makes up less than one percent of all water on the globe, and is the only thing the world's 7 billion people can drink -- in your home.
Among our favorites:
- Install low-flow showerheads and faucet aerators to save water and energy.
- Install a low or ultra low-volume toilet.
- Eat less meat -- especially beef. "A typical hamburger can take 630 gallons to produce," Postel writes.
- Buy less stuff. Why? Because everything takes water to make.
Which suggestions do you think are the least disruptive to your way of living? And do you think a price on water is necessary for consumers to value it?
