Betsy Bayha of member station KQED in San Francisco reports on the debate over the dumping of trash and toxic waste from Navy ships. The Navy has until the end of this year to comply with the same strict dumping regulations as commercial vessels, but the service says it can’t meet the deadline, and has asked for at least another five years to come into line. The issue has come back into focus recently because of the court-martial of a sailor for refusing orders to dump waste into the open ocean.
