From sargassum to the blue economy: a sustainable opportunity for the Greater Caribbean In recent years, widespread sargassum blooms have become a growing concern in the Greater Caribbean. Once a symbol of marine biodiversity on the high seas, this macroalgae now covers beaches from Barbados to Mexico, threatening tourism, livelihoods, ecosystems, and, crucially, public health. As climate change warms the oceans and alters nutrient flows in rivers like the Amazon, sargassum thrives. However, when it reaches the coast and begins to decompose, it emits toxic gases, primarily hydrogen sulfide and ammonia, posing increasing risks to human health, in addition to having a significant impact on tourism in the region.
