For years, experts have been warning about looming shortages of drinkable water — not only in hot spots such as the Middle East, but in the United States as well. Now a seven-part video series from NBC Learn and the National Science Foundation delves deeply into the scientific and social issues surrounding one of the world's most important resources.
"Sustainability: Water" starts out with a tutorial on the global water cycle, which transports water through the air, land and seas. The series takes a closer look at the places in America where worries about water are already rising:
“Most Americans take water for granted,” Roger Wakimoto, assistant director for NSF’s Directorate for Geosciences, said in a news release. “We have occasional water restrictions, but for most of us, when we turn on the tap, water is there. This series with NBC Learn aims to help people become more conscious of the threats to our water supply and understand the steps that need to be taken to maintain it.”
"Our new series with NSF is an excellent opportunity to raise awareness about the challenges to our environment,” said Soraya Gage, who is general manager of NBC Learn, the educational arm of NBC News. "By exploring the challenge of sustainable water, we hope to raise awareness and spur dialogue about managing the water system and conserving Earth’s most precious resource.”
