Green seaweed
Green seaweed is part of Brittany’s marine ecosystem. The common name for it is ‘sea lettuce’ because it looks like a large lettuce and is edible.
In spring and summer, in certain bays, located mainly in the north of Brittany, an abnormal increase in its growth can cause what are known as ‘green tides’. Why does this phenomenon occur? Where does it happen? Is it dangerous to health? What can we do about it?
