Human Water Cycle

Water. It's an essential building block of life, constantly moving in a hydrologic cycle that flows in a continuous loop above, across and even below the Earth's surface. But water is also constantly moving through another cycle -- the human water cycle -- that powers our homes, hydrates our bodies, irrigates our crops and processes our waste. The tight connection between water, food and energy makes them dependent on one another.

Our increasing need for these three vital resources is forcing us to rethink how we manage and use our water supply. The National Science Foundation (NSF) has joined with NBCLearn to explore the Human Water Cycle. Check out these four videos to learn more about the connections between water, food and energy.

We have archived the special report, "Human Water Cycle." You can still access the 4-part video series via our Multimedia Gallery. If you have any questions or concerns, please contact the OLPA Webteam.
