Role of Science in Solving the Earth's Emerging Water Problems
"...As the world scrambles to meet ever-growing water demands, the likelihood is that ecosystems will suffer untold damages. More than 50% of the world's wetlands have been lost since 1900, and as many as 80 fish species have become extinct. Sixty percent of the world's 227 largest rivers are subject to serious flow disruption from dams, diversions, and canals, leading to degradation of downstream ecosystems. Every day, 2 million tons of human waste are disposed of in rivers and streams. Moreover, our understanding of aquatic ecosystems and their water requirements is rudimentary at best. The task of maintaining and enhancing water based environments while providing water for basic human needs and economic growth will be enormous."
