Sargassum is a free-floating brown seaweed that supports marine life in the open ocean and gives the Sargasso Sea its name. In recent years, however, massive blooms have expanded across the tropical Atlantic—forming the Great Atlantic Sargassum Belt, a 5,000-mile stretch from West Africa to the Caribbean and Gulf of Mexico—driven by warmer waters and nutrient pollution.
While beneficial offshore, excess sargassum can be destructive when it reaches land. It clogs beaches, damages coastal ecosystems, disrupts tourism and fisheries, and creates low-oxygen “dead zones.” As it decays, it releases hydrogen sulfide gas, posing risks to human health and local economies.
At the same time, this growing challenge is creating new opportunities. A wave of entrepreneurs is working to intercept and repurpose sargassum, transforming it from an environmental nuisance into a potential source of value-added products and a foundation for a new green industry.
