Beneath the surface, seaweed grows into underwater forests that matter as much to ocean life as trees do on land. This talk, streamed live from Aarhus University, looks at 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 explores the sustainable solutions seaweed may offer for climate, biodiversity and future food, and whether it really can be the answer to the crises it is often praised for. It is an updated version of a lecture first given in autumn 2020, and it is part of the public lecture series in natural sciences run by Aarhus University with partners in towns across the country.
