AMOCO CADIZ (1979) Litres of oil spilled: 254 million Estimated damage: $284 million The Amoco Cadiz hit rocks near the coast of Brittany and eventually split in two; leaking oil that destroyed the region's prized oyster beds.

The Braer crashed into the rocks around the Shetland Islands. Most of the spilled crude oil dispersed in the stormy sea, but airborne oil particles coated the Islands' sheep. They survived, though four otters were killed, two of them run over by a news camera crew. EXXON VALDEZ (1989) Litres of oil spilled: 42 million Estimated damage: $8 billion Joseph Hazelwood (right) captained his crew right into an Alaskan reef, dumping oil in the waters of Prince William Sound. Exxon has already paid $3 billion in cleanup costs and fines, but it is appealing an additional $5-billion charge in punitive damages. ERIKA (1999) Litres of oil spilled: 16.6 million Estimated damage: $860 million The Erika spewed thick oil on France's unspoiled northwestern beaches. Half of the total cost of damages was awarded to the tourism sector. French oil group TotalFina, which chartered the tanker, had its share price battered on the stock exchange in the weeks following the accident. JESSICA (2001) Litres of oil spilled: 682,000 Estimated damage: $2 million*

A navigational error caused this spill near San Cristobal in the Galápagos Islands, threatening colonies of sea lions, marine iguanas and sea urchins. The $2-million price tag is expected to quadruple before the cleanup effort is over.
