Seaweed is two billion years old. There are three big families: green, red, and brown seaweed, and they are each very different.
Green seaweed moved on land half a billion years ago and gave birth to all the vegetation we have now. It is genetically closer to an oak tree than it is to a red seaweed. The difference between red seaweed and green seaweed is bigger, from a genetic perspective, than the difference between a fungus and an elephant. This very wide area of genetic diversity offers an equally diverse range of applications.
These revelations were shared by Vincent Doumeizel, author of ‘The Seaweed Revolution, in our recent webinar hosted in partnership with Bright Tide and the University of Plymouth. The webinar covered the incredible range of applications of seaweed and reflects its role as a vital part of a sustainable ocean economy.
