FALL OF THE MEDITERRANEAN
Apart from the nine-mile-wide Strait of Gibraltar, the Mediterranean is landlocked, virtually unable to cleanse itself. It takes 80 years for the water to be renewed, far too slow a process to cope with the remorseless rush of pollution.
For centuries, the people of the Mediterranean have used the sea for their wastes. Weak coastal currents keep sewage and industrial waste close to the shore and gently spin floating oil and tar towards the beaches. And the sea’s feeble currents can do little to help remove them. Vast areas of the shallows of the Mediterranean – the beaches are awash with bacteria and it doesn’t take long for these to reach people.
An even greater danger is involved in the seafood dishes that add so much pleasure to holiday menus. Shellfish are prime carriers of many of the most vicious diseases of the area. They often grow amid pollution. And even if they don’t, they are infected by the popular practice of ‘freshening them up’ – throwing filthy water over them in markets.
