Beneath the surface, seaweed forms underwater forests that matter as much to ocean life as forests do on land. They shelter fish and small creatures, help balance the sea and the climate by absorbing nutrients and CO2, and release oxygen.
This lecture asks whether seaweed can really help solve today's challenges in climate, food and biodiversity. The speakers explain what seaweed and algae actually are, how they differ from plants and animals, and how they are cultivated both in the sea and on land. The evening also looks at sustainable uses for the future, and includes a chance to taste seaweed.
This is an updated version of a lecture first given in autumn 2020. It is part of the public lecture series in Natural Science run by Aarhus University, with support from the Carlsberg Foundation.
