Environmental disaster is looming in the Galapagos Islands, the Pacific archipelago whose unique wildlife inspired Charles Darwin's theory of evolution. Already under pressure from a rapidly growing population and mass tourism, the waters around the Galapagos face being devastated by one of the world's most wildlife-damaging fishing methods. The Galapagos have been officially protected for nearly 20 years and form part of the Galapagos World Heritage Site. But now the islands' 1,000 fishermen want to introduce long-lining - a technique involving lines many miles long holding hundreds of thousands of baited hooks, which catch and kill as many birds and animals as the fish that are targeted.
