There are many ways to protect coastlines, and in this video, see why oyster reefs are one of the most important lines of defense we have. In many marsh and sea-grass environments, the balance of the ecosystem is maintained due to the shelter provided by oyster reefs, but human impact has caused a massive decline of natural oyster formations in the last century. See how humans are working together to build artificial oyster reefs, and learn about the benefits of using natural resources to save these sensitive coastal ecosystems.
