Seaweed // livestream from Aarhus University

Seaweed is not a plant - it is algae. Beneath the ocean's surface, they grow in a wealth of colours, shapes and sizes, and the kelp forests along the world's coasts play as central a role in marine ecosystems as forests do on land. Seaweed provides food and shelter for fish and small animals, absorbs nutrients and CO2, produces oxygen and counteracts ocean acidification.

Humans have used seaweed as a resource since time immemorial - for food, feed, fertilizer, gunpowder and materials. Today seaweed is often mentioned as a solution to climate crisis, food crisis and biodiversity crisis, but does it really hold up?

The lecture covers what seaweed and algae actually are, what distinguishes them from plants and animals, and how they are cultivated - both in the sea and on land. There will also be a focus on the sustainable solutions seaweed can contribute in the future, and there is an opportunity to taste seaweed.

The lecture is part of Aarhus University's series "Public Lectures in Natural Science" and is livestreamed to Byens Bio in Jelling. The livestream starts at 19:00, and doors close at 18:45. Free entry - no registration required.
