题目

阅读理解     The New Caledonian barrier reef (堡礁)is located in New Caledonia in the South Pacific, and is the second longest coral reef in the world, after the Belize Barrier Reef.     The New Caledonian barrier reef surrounds Grande Terre, New Caledonia's largest island, as well as the Ile des Pins and several smaller islands, reaching a length of 1,500 km. The reef encloses (围住)a lake of 24,000 square kilometers, which has an average depth of 25 meters. The reefs lie up to 30 kilometers from the shore，but extend almost 200 km to the Entrecasteaux reefs in the northwest. This northwestern extension encloses the Belep Islands. Several natural passages open out to the ocean. The Boulari passage, which leads to Noumea, the capital and chief port of New Caledonia, is marked by the Amedee lighthouse.     The reef has various species, and is home to endangered dugongs, a kind of sea animal, and is an important living site for green sea turtles.     Most of the reefs are generally thought to be in good health. Some of the eastern reefs have been damaged by waste water from nickel mining(镍开采) on Grande Terre. The waste from mining and agriculture has affected reefs near river mouths, which have been worsened by the destruction of forests, which help to keep waste. Some reefs have been buried under several meters of waste.     In January 2002, the French government proposed listing New Caledonia's reefs as a UNESCO World Heritage Site. Later on, UNESCO listed the New Caledonian barrier reef on the World Heritage List on July 2008. （1） What can be learned according to the passage? A .
