Decaying seaweed poses a severe threat to our oceans and their coastal ecosystems, choking marine life such as fish, lobsters, and crabs. Its suffocating presence extends to coral reefs, seagrass, and mangroves, and prevents sea turtles and seabirds from nesting.

Decaying seaweed triggers a foul-smelling odour through its decomposition, resulting in skin irritations and respiratory difficulties as it releases hydrogen sulfide gases. Its repercussions further extend to impact water and power supplies, while also contributing to the creation of substantial landfills, compounding the issue.

Inflicting financial losses across various sectors, this grave threat impacts fisheries and livelihoods. The hotel industry, encompassing resorts, yacht clubs, marinas, and others, grapples with declining tourism and surging costs.
