Can 'water footprinting' help cut the 500 liters of H2O needed to produce a carton of OJ? Carbon trading promotes good behavior by creating a standardized currency representing a verifiable environmental benefit. Payments for watershed services do the same for cutbacks in water pollution, albeit on a smaller scale. Now, the Nature Conservancy and the Coca-Cola Company are experimenting with a new method of "water footprinting" that could do the same for total water use - a key component in the development of a market-based scheme that would promote responsible water usage.

"Use the Interactive Footprint Calculator to find your country and see how it compares to others. See what makes up the biggest components of our water footprint. Watch how the index for species populations move and change over time."

This map represents one possible supply chain for a running shoe. Two petroleum-based synthetics-polyester and polyurethane-make up 36 percent of the weight of a typical running shoe, including packaging; these synthetics are responsible for 57 percent of the carbon footprint of the shoe's materials. From extraction to the end of the shoe's life, the entire carbon footprint of this typical pair of running shoes is equivalent to using a 100-watt light bulb for a week.

Human Footprint reveals the lifetime consumption of an average American including the resources needed to produce, package and transport everything consumed.

"Young Voices on Climate Change is a series of short films featuring young people using science and data to reduce the carbon footprint of their homes, schools, communities, and states. "

"Young Voices for the Planet is a film series featuring young people who are making a difference! They are shrinking the carbon footprint of their homes, schools and communities. You, too, can do something about global warming! As Alec Loorz says, "Kids Have Power.""

Worldchanging.com founder Alex Steffen argues that reducing humanity's ecological footprint is incredibly vital now, as the western consumer lifestyle spreads to developing countries.

"Buy, Use, Toss? A Closer Look at the Things We Buy is an interdisciplinary unit that includes ten fully-planned lessons. This unit is correlated with national science and social studies standards and will lead your students through an exploration of the system of producing and consuming goods that is called the materials economy. Grades: 9-12 Subjects: Science, Social Studies"
