A historic surge of sargassum seaweed blanketed Caribbean coastlines in May, smothering beaches from Puerto Rico to Guyana and triggering widespread ecological and economic disruptions. Scientists warn the algae influx—already the largest on record—could intensify in June, compounding challenges for coastal communities.
Tourism, Wildlife, and Health at Risk
The brown, prickly algae has clogged fishing harbors, driven tourists away from popular resorts, and suffocated marine life. In Martinique, toxic gases released by decomposing sargassum forced a school closure, highlighting health risks for residents. Local businesses report losses as beachfronts vanish under meters-thick mats of seaweed.
Climate Link Under Scrutiny
Researchers attribute the surge to warmer ocean temperatures and nutrient runoff from agriculture, suggesting climate change may be accelerating the phenomenon. “This isn’t just an eyesore—it’s a systemic threat to coastal economies,” said marine biologist Dr. Alicia Fernandez, who tracks sargassum patterns.
Regional Response Intensifies
Authorities across the Caribbean are deploying cleanup crews and exploring algae repurposing projects, from fertilizer production to biofuel research. However, funding gaps and the sheer scale of the influx continue to strain resources.
