Learn that the green colour and the turbidity of the North Sea is not caused by pollution, but an abundance of algae and plankton. These micro-organisms form the basis for a healthy food chain. Herring, mackerel, porpoises and killer whales benefit from this. How do these large predators live and survive in the North Sea?
