The Mulch farm policy website says the EPA isn’t doing enough to combat the “dead zone” in the Gulf of Mexico:

The EPA Task Force ignores it’s own Science Advisory Board’s recommendation that they adopt a 40-percent nutrient reduction goal for the Basin. This policy is a critical first step to ensuring the Task Force can achieve the goal of reducing the size of the Dead Zone to 5,000 square kilometers.

Fertilizer and manure runoff from farm fields is listed as the “leading cause of hypoxia in the Mississippi River Basin and the Gulf of Mexico.”
