What's your water footprint?

Journalist Thomas Kostigen's tips for reducing your water consumption.

The average American uses 656,000 gallons of water per year. Nearly everything we touch, eat, wear and drive has a “water cost.” In The Green Blue Book, author Thomas Kostigen argues that conserving this vital resource is the most important thing people can do to help save the planet. In advance of World Water Day, Kostigen joins Larry in studio to explain how simply redirecting our daily actions can shore up the world’s water supply.
