The Mediterranean Sea is a world of impressive diversity where ocean sunfish and whales live side by side, and colourful corals provide a home for smaller creatures. But human beings have left their mark here for thousands of years: ancient shipwrecks and fighter planes from the Second World War litter the ocean floor, while until recently raw sewage was fed straight into the sea. The impact has been devastating – today the Mediterranean is an ecosystem on the edge. But there is a glimmer of hope as measures to protect the sea from pollution and excessive disturbance are being put into place.
Sandrine Ruiton from the University of Marseille specialises in research on artificial reefs to build up the lost marine biodiversity near cities like Marseille, one of the Mediterranean’s busiest ports. Until recently it was responsible for seriously polluting the surrounding Mediterranean Sea. Christian Petron himself has been instrumental in raising awareness of this ecosystem in dire straights. His own 30-year-old archive footage shows the extent of the pollution in graphic detail.
