Sustainable Solutions: Water Shortages
Over the next forty years, the global population is expected to increase from 6 billion to an estimated 9 billion, yet the world’s water supply is constant. Only 3 percent of the global water supply is fresh; the majority of it is locked in ice or stored deep in the earth, making its extraction very expensive. The remaining 97 percent is found in the oceans and is too salty for human consumption, irrigation, and industrial uses. Water from the oceans can be processed; however, desalination is an energy-intensive practice. In this course we will explore site strategies for reducing water waste and recharging groundwater supplies.
