Beneath the surface, seaweed forms underwater forests that matter as much to ocean life as forests do on land. Seaweed provides food and shelter for countless marine creatures, takes up nutrients and CO2, produces oxygen and helps counter ocean acidification.
This talk asks whether seaweed really can help solve the challenges of climate, food and biodiversity, as it is often claimed to do. It explains what seaweed and algae actually are, how they differ from plants and animals, and how they can be farmed both at sea and on land. The evening also looks at sustainable solutions for the future, and includes a tasting that takes you into the flavour world of seaweed.
This is an updated version of a talk first given in autumn 2020. It is streamed live from Aarhus University as part of the public natural science lecture series.
