Sargassum seaweed, once a crucial part of marine ecosystems, has now transformed into a significant coastal issue due to nutrient-rich runoff from land. This rapid growth of brown macroalgae poses serious environmental and economic challenges, threatening tourism and local livelihoods. Scientists are investigating the interplay of nutrient shifts and ocean currents to resolve this issue, emphasizing that tackling land-based pollution is vital to curb the spread of sargassum.
