In 40 years, US could face water crisis
Global warming and climate change are likely to unfold a water crisis in the United States within the next 40 years, says a new report.
It concluded that seven in 10 of the more than 3,100 US counties could face risk of fresh water shortages. The report includes maps that identify those places.
Sujoy B. Roy, director for research and development (R&D), Tetra Tech Inc., Lafayette, US, and colleagues explain that population growth is expected to increase the demand for water for municipal use and for power generation beyond existing levels.
