Global seaweed production and trade have witnessed significant growth, driven by demand in the food, cosmetics, and pharmaceutical industries. Seaweed farming is highly productive and environmentally beneficial, as it absorbs carbon dioxide and provides habitats for marine life. Major producers like China, Indonesia, and South Korea lead in the cultivation of popular seaweeds such as nori, kelp, and carrageenan-producing varieties. Trade has expanded due to increased interest in plant-based products and sustainable resources. However, challenges in sustainability and ecosystem management call for responsible practices to ensure that seaweed farming remains beneficial for both local economies and the environment.
