Eating seaweed is not a novel concept. Algae is a staple part of diets across Asia and in developing countries, and coastal communities have been benefitting from seaweed farming for centuries. In recent years there has been a realisation that oceans need to play a greater role in the future of food with population growth accelerating, large scale meat farming being unsustainable and having issues with animal welfare, and limitations on land space for crops.
Seaweed is one of the most sustainable sources of food, and a study estimated that seaweed farms the size of Washington State could provide enough protein for the entire world’s population. There has therefore been growing interest in introducing seaweed into European diets with numerous companies coming up with innovative ideas as to how it can be made attractive. The success of these companies has to date been based almost entirely on the harvesting of wild seaweed and there is limit to availability, and how much can be taken out of the environment without having an impact on ecosystems. There is therefore a growing need for secure, sustainable supplies and GreenSeas is looking to supply this demand from its commercial seaweed farms.
