Seaweed forms spectacular underwater forests that matter enormously for ocean life and the climate. This talk asks whether seaweed can really help solve some of the biggest challenges of our time, from health and food to climate and the environment.
The speaker explains what seaweed and other algae actually are, how they differ from plants and animals, and how seaweed is cultivated both in the sea and on land. The evening also looks at sustainable uses of seaweed for climate, biodiversity and future food, and ends with a chance to taste your way through the flavours of seaweed.
This is an updated version of a talk first given in autumn 2020. It is part of the public science lecture series Offentlige foredrag i Naturvidenskab, organised by Aarhus University and supported by the Carlsberg Foundation.
