Explanation:
Tampa, Fla. (Aug. 25, 2015) - Fresh water--connecting and sustaining all aspects of life on Earth, including food and energy--is in great danger. Moreover, scientists are worried not only about fresh water; they worry that we are not worried enough about fresh water, especially in light of growing concern over recent events, such as the prolonged California drought. The current Special Issue Section of Technology and Innovation - Journal of the National Academy of Inventors has a special section devoted to fresh water and the challenges it faces from us and from the changing environment.
"As the global population expands, climate change, overexploitation of water resources, pollution, and economic growth are impacting the availability of water," said Vimal Chaitanya, vice president for research and professor of mechanical engineering and chemical and materials engineering at New Mexico State University, and Frederic Zenhausern, professor of basic medical sciences and radiation oncology at the University of Arizona College of Medicine and director of the Center for Applied Nanobioscience and Medicine at the University of Arizona, in a lead-off editorial. "As a result, society faces an unprecedented challenge to advance science and develop appropriate technological innovations to ensure water security," they conclude.
