Seaweed forms spectacular underwater forests that matter both for ocean life and for the planet's climate. This talk looks at what seaweed actually is, and why it is not a plant at all but an alga, and at how it differs from plants and animals.
The evening also explores how seaweed can be grown, both in the sea and on land, and what sustainable solutions it might offer for climate, biodiversity and future food. Can seaweed really be the answer many hope for? The talk tests that question, and ends with a chance to taste the future in seaweed's flavour world.
This is an updated version of a talk first given in autumn 2020. It is part of the public science lecture series run by Aarhus University in partnership with hosts in several cities.
