This week on World Ocean Radio we're introducing listeners to the Water Ethics Charter-- recommendations from a global Water Ethics Steering Committee with draft principles for water sustainability based on five themes: environmental, economic, social, cultural, and governance.  World Ocean Radio provides coverage of a broad spectrum of ocean issues from science and education to advocacy and exemplary projects. World Ocean Radio, a project of the World Ocean Observatory, is a weekly series of five-minute audio essays available for syndicated use at no cost by college and community radio stations worldwide. World Ocean Radio is produced in association with WERU-FM in Blue Hill, Maine and is distributed by the Public Radio Exchange and the Pacifica Network.
