Dead zones off the coast, are fueled by nutrient runoff from agricultural and other human activities in the Mississippi River watershed, which stimulates an overgrowth of algae that sinks, decomposes and consumes most of the life-giving oxygen supply in bottom waters. These chronic, recurring hypoxic zones every summer represent a significant threat to Gulf coastal ecosystems.
