This article goes into the research being done on oyster reefs and their ability to slow the progress of soil erosion on the coast of Louisiana. At the four control sites in the study, the oyster reefs were able to half the rate of erosion over a few months. One interesting social concept behind this environmental problem is how restaurants used to return used oyster shells to fisherman. Fisherman would then return these shells to the ocean and oyster reefs were created through this process. According to the article, only one or two restaurants still do this. Now, oyster shells are sent to landfills, where they are processed in useless ways.
