摘要
California is quickly reaching the point where each unit of water used to raise crops costs more in ecological damage than it provides benefits of crops, said Peter Gleick, president of the Pacific Institute, during the Stanford Graduate School of Business annual environmental lecture.
Politicians and engineers have grappled for years with solutions to California's water shortages. It's unlikely more dams or huge infrastructure projects will be built, so what's the alternative?
Gleick called for looking to other kinds of water supply, such as treated wastewater, desalination, or rainwater harvesting. Maintaining the infrastructure we already have is important, as well as growing crops that take less water. And he called for proper pricing mechanisms and markets to limit cheap water.
Gleick spoke at the 2010 Conradin von Gugelberg Memorial Lecture on the Environment.
