There is a lot of pollutants coming from Septic Tanks and farm run off. It is evident from the algae that has bloomed throughout the Negril and Bloody Bay reefs. There are caves throughout the area, and run off into the caves, some of which are being used as septic tanks and trash dumps makes its way to the river and to the sea. Dealing with this run off and illegal dumping of trash and sewage remains a problem.
Another problem is the development of areas that once were swamps and mangroves. These areas were natural filters and nurseries for many of the fish species that frequent the reef. It is no coincidence that problems with the reef and rivers coincide with the loss of these swamps and mangroves.
A real and complete study of the Negril ecosystem along with a development moratorium needs to be done. After all, once the reef is degraded and the fish gone, so goes the beach and then Negril.
