This Seaweed Was a Caribbean Disaster, Now It's Gold. Head over to eightsleep.com/mattferrell and use the code MATT to get $200 off Pod 5 Core and $350 off Pod 5 Ultra. Caribbean beaches are ankle-deep in slimy, smelly seaweed. Wave after wave of sargassum is blanketing shorelines from Barbados to Cancún. It traps sea turtles. It smothers coral reefs. And it drives tourists away from islands that depend on them. This seaweed isn't just crashing weddings on the beach. It's crashing Caribbean economies. But what if sargassum wasn't just a mess, but a raw material? What if we could turn it into bricks, biogas, and even buttery soft T-shirts? What if the right refining is all it takes to transform this weed into biodegradable packaging and high-performance composites? This is the story of how Caribbean and international start-ups are transforming the seaweed invasion into a sustainable resource. And we all get the t-shirts.
