Seaweed forms underwater forests that matter as much to ocean life as forests do on land, and to the climate too. This free public lecture, streamed live from Aarhus University, asks whether the growing claims that seaweed could help solve the world's biggest challenges actually hold up.
The talk explains what seaweed and other algae really are, how they differ from plants and animals, and how they are farmed both in the sea and on land. It also looks at sustainable uses in climate, biodiversity and future food, with a tasting of seaweed flavours as part of the evening. The lecture is an updated version of a talk first given in autumn 2020.
