Beneath the surface, seaweed grows into underwater forests that matter as much to ocean life as forests do on land. This public lecture looks at what seaweed and other algae actually are, and why they are not plants or animals.
The talk also explores how seaweed is farmed both at sea and on land, and whether it can help with climate, biodiversity and future food. It is an updated version of a lecture first given in autumn 2020, and it ends with a taste of seaweed's flavour world.
