Cuba is dealing with a critical environmental disaster as massive amounts of sargassum seaweed inundate the japanese shoreline of Guantánamo province. In response, the Cuban Ministry of Science, Expertise and Atmosphere (CITMA) has issued a most alert, citing each environmental and public well being dangers.
In response to an official assertion from CITMA’s regional delegation, the heavy focus of decomposing sargassum is releasing poisonous gases equivalent to hydrogen sulfide and ammonia. These emissions could cause eye, nostril, and throat irritation, together with complications, nausea, dizziness, and respiratory problems — notably amongst people with bronchial asthma or allergy symptoms.
The alert additionally warns of potential pores and skin and gastrointestinal infections, because the decaying seaweed hosts dangerous micro organism that may unfold by means of direct contact or contaminated water.
Consultants hyperlink this phenomenon to local weather change, highlighting rising sea temperatures, shifts in ocean currents and wind patterns, and nutrient air pollution (notably nitrogen and phosphorus) as key contributing components.
Native authorities and volunteers — together with college students and college from native medical faculties — have launched cleanup efforts in affected leisure areas like Tortuguilla Seaside. Nonetheless, the scope of the invasion is elevating main issues.
Satellite monitoring has revealed an enormous belt of sargassum drifting throughout the Atlantic. Until dispersed by climate occasions like tropical storms, this 12 months’s landfall might exceed the file set in 2018, when greater than 522,000 tons reached the Caribbean.
Communities equivalent to Baracoa, San Antonio del Sur, Baitiquirí, and El Guanal are already reporting extreme impacts, together with overwhelming odors, respiratory issues, marine life die-offs, and corrosion of metallic infrastructure. The native fishing trade and tourism sector are additionally beneath risk, with little fast assist accessible.
The CITMA has urged residents to keep away from direct contact with the seaweed and to remain knowledgeable by means of official channels.
The place Does the Sargassum Come From?
Traditionally, sargassum reaching the Caribbean has originated from the Sargasso Sea within the North Atlantic. Nonetheless, in recent times, scientists have recognized a brand new supply: the Nice Atlantic Sargassum Belt, stretching from West Africa to Brazil.
Fueled by ocean currents, commerce winds, and nutrient-rich runoff from rivers just like the Amazon and Congo, these huge floating lots journey hundreds of kilometers to succeed in the Caribbean Sea and Gulf of Mexico.
As Cuba grapples with the rising scale of the invasion, environmental specialists warn that that is not a seasonal downside, however a long-term structural challenge requiring coordinated worldwide motion and pressing mitigation efforts.
