The Sargassum Belt poses significant challenges to coastal communities, particularly in the Caribbean and Gulf of Mexico. The algae's annual arrival disrupts tourism, artisanal fishing, and local economies, with cleanup costs running into hundreds of millions of dollars. When the algae decompose on beaches, they release toxic gases like hydrogen sulfide, which can harm human health and degrade air quality. The persistent nature of the belt has turned what was once considered an emergency into a long-term environmental and economic issue. Without effective management, the belt's impacts are expected to continue affecting livelihoods and ecosystems in the region.
