Every year, vast quantities of sargassum seaweed wash up on the shores of the Caribbean and Gulf of Mexico, disrupting local ecosystems, economies, and tourism. What was once a seasonal phenomenon has now become an annual challenge—one that scientists have dubbed the Great Atlantic Sargassum Belt.
The proliferation of sargassum, once confined mainly to the Sargasso Sea, has surged across the Atlantic since 2011, impacting everything from coastal habitats to resort beaches. Experts point to climate changes, nutrient runoff from major rivers, and shifting ocean currents as key drivers of this dramatic change.
While sargassum provides critical ecological benefits—serving as habitat and food for marine life—its presence on the shore brings serious challenges. Decomposing sargassum releases greenhouse gases, threatens coral reefs, and clutters beaches, hurting tourism-dependent economies.
That being said, scientists and entrepreneurs are exploring creative ways to use sargassum as a resource:
— In Quintana Roo, Mexico, researchers are working to convert sargassum into green gas, potentially reducing carbon emissions and creating a new energy source.
— From fertilizers to skincare products, new industries are emerging to transform sargassum into valuable goods.
— Companies like Seaweed Generation are developing solar-powered robots to collect and sink sargassum back into the ocean—reducing its harmful impact on coastal ecosystems.
With the right strategies, sargassum can be transformed from a seasonal nuisance into a sustainable asset. Continue reading this article here: https://bit.ly/3YID7EJ

Every year, vast quantities of sargassum seaweed wash up on the shores of the Caribbean Sea and Gulf of Mexico, threatening coastal communities’ economies and ecosystems. Comprising two free-floating species (Sargassum natans and Sargassum fluitans), the macroalgae is by no means new to the region...
