The Galapagos a far-away archipelago(群岛) and largely untouched by man, is now facing a problem. Its local people, who live on the island of Santa Cruz, want to develop the business and tourist potential（旅游资源）of the island. Recently, they are locked in a bitter struggle with the naturalists who work at the Charles Darwin Centre, also on Santa Cruz. The naturalists want to protect the island’s wildlife which is already suffering as a result of human activity.

The animals’ great threat used to be sailors who, hundreds of years ago, robbed the islands for food. They wiped out about 250,000 Giant Tortoises. For example, on Pinta, one of the smallest islands, there are no Giant Tortoises left at all. The last survivor, an 80-year-old Giant Tortoise called Lonesome George, lives under the protection of naturalists at the Darwin Centre.

Today, the island’s animals are no longer hunted for food. But other dangers have replaced the threat from sailors. Goats, for example, introduced over the years by man, have gone wild. With no natural enemies, their number has reached 10,000 on the largest of the Galapagos islands, Isabella. They are eating huge quantities of plants, and robbed the remaining Giant Tortoises of food. The problem is now so bad that the National Park Service has hired hunters to kill the goats in order to save the Giant Tortoise from dying out.
