Seaweed forms spectacular underwater forests that matter enormously for marine life and for the climate. This public lecture looks at what seaweed actually is, and why it is not a plant but an alga, and at how it could help tackle challenges in health, food, climate and the environment.
The talk covers how seaweed binds nutrients, takes up CO2, produces oxygen and counters ocean acidification, and how it can be cultivated both at sea and on land. It also asks whether seaweed really is the solution to the world's problems that it is often made out to be. The evening ends with a tasting, where you get the chance to sample the flavours of the future.
This is an updated version of a lecture first given in autumn 2020. It is part of the public science lecture series from Aarhus University, held in collaboration with hosts in towns across Denmark and supported by the Carlsberg Foundation.
