Seaweed forms underwater forests that matter both for life in the sea and for the climate. In this free online talk, marine ecologist Annette Bruhn, senior researcher at Aarhus University, explains what seaweed actually is. Seaweed is algae, not plants, and the talk looks at how it differs from both plants and animals.
The lecture also covers how seaweed is grown, both in the sea and on land, and what sustainable solutions it may offer for climate, biodiversity and future food. Recent research suggests seaweed could help with challenges in health, food, climate and the environment, and the talk asks how far that promise holds.
The livestream is part of the public science lecture series Offentlige foredrag i Naturvidenskab, which brings the latest discoveries in natural science to a wide audience. All lectures in the series are streamed from Aarhus University.
