Seaweed forms underwater forests that matter for ocean life and the climate, and new research suggests it could help with challenges in health, food, climate and the environment. In this talk, marine biologist Annette Bruhn explores what seaweed and other algae really are and how they differ from plants and animals.
The session also covers how seaweed is grown both in the sea and on land, and which sustainable solutions it could offer for climate, biodiversity and future food.
