Trying to Solve the Marine Debris Problem

Since the early 1970’s, when Chief Iron Eyes Cody shed a tear on a television commercial, we have been trying to reduce the amount of solid waste found along our beaches and within our waters.   Though numerous agencies and civic groups, led by the Ocean Conservancy, have held beach and underwater clean ups over the …
