Taped by WGBH Forum Network, Curtis Felix visited the New England Aquarium to talk about his project to clean up the Wellfleet harbor using and recycling oysters.

Felix explains his work in Wellfleet and how it's already changed the quality of the water to within the U.S. Environmental Protection Agency's "excellent" standards.  He also delves into the cost benefits of using oysters and why it's important.
