Mussels and seaweed is one way to go for a cleaner Copenhagen harbour. On Kalvebod Bølge, or Kalvebod Wave, on the Danish capital’s waterfront, the organization Havhøst is cultivating life under water.
Unlike mussels, the seaweed does not clean the water, but it uses nutrition to grow and then becomes an edible leaf.
By removing nutrients from the water like this, growing seaweed helps the ocean, she continues.
The water in the Copenhagen harbor is at the moment clean enough for swimming, but not necessarily for eating the mussels. Kathrine Strange thinks this could be possible in the future.
She adds that more initiatives like this are needed for a cleaner harbour. As well as for strengthening the Danes’ relationship to the water which they are surrounded by.
