How seaweed is surprisingly useful

From powering cars to feeding farm animals, how using seaweed more can help the planet. We hear how a local business in Barbados is using sargassum seaweed to power cars, providing an eco-friendly alternative for islanders and potentially helping to clear the beaches of smelly seaweed. Also we visit the European company aiming to replace single-use plastics with seaweed-based packaging. And how feeding seaweed to cattle can dramatically cut emissions of planet-warming methane gas.
