For more information about overfishing in the Mediterranean Sea, this video (provided by Ocean Health Index) is very interesting and is a very quick and easy way to understand what is happening in the Mediterranean, and how it is effecting both species on land and in the water.
For more information about Greenpeace and the types of action that they are taking to combat overfishing, watch this video! It is a very good example of one of their protests in the Mediterranean Sea, where they are attempting to prevent a tuna ranching operation from removing a large cage full of Bluefin tuna (an endangered species due to overfishing) from the sea.
