Seaweed resources encompass a wide range of edible and industrially valuable algae species that are harvested from marine and freshwater environments. Known for their high nutritional value, seaweeds are used in food, cosmetics, fertilizers, and biofuel production. Their cultivation is eco-friendly, as seaweed absorbs carbon and nitrogen, helping to mitigate water pollution and climate change effects. Leading countries in seaweed production have established sustainable harvesting practices to meet growing demands while preserving marine biodiversity. Investing in seaweed resources holds promise for economic growth, environmental benefits, and contribution to global food security, making it a valuable resource for the future.
