From the California WaterBlog, in a post by Jay Lund, Jeffrey Mount and Ellen Hanak:
As the effects of the drought worsen, two persistent water myths are complicating the search for solutions. One is that environmental regulation is causing California’s water scarcity. The other is that conservation alone can bring us into balance. Each myth has different advocates. But both hinder the development of effective policies to manage one of the state’s most important natural resources.
