Major Oil Spills Since 1967
The size of an oil spill is an indication of its potential environmental impact. Yet, the two most damaging oil spills were not the largest but took place nearby ecologically rich areas, particularly in terms of fishing. The Amoco Cadiz was carrying 223,000 tons of oil when it sank in Portsall Bay, France, on March 17, 1978. Some 400 km of Breton coastlines were affected. Following the incident, not only was the ecological equilibrium greatly disturbed but local economy - based on fishing - was also completely paralyzed. On March 24, 1989, the oil tanker Exxon Valdez hit a reef in Prince William Sound, Alaska, thereby spilling 37,000 tons of oil of its 180,000 tons load along 1,700 km of coastlines. Even if comparatively to other major spills it was of lower volume, it still carries today the title of the largest animal death toll.
The Prestige and Sea Empress oil spills that occurred off in the European Atlantic generated a significant amount of pollution that destroyed aquatic species including algae, mollusks, crustacean, marine mammals, fish and invertebrates.
