Nina is reading a book which described 37 endangered natural and cultural treasures in the world. The writers want the book to be a hopeful call to action. Here are some examples of these places.
Mount Kilimanjaro
Mount Kilimanjaro in northeastern Tanzania, is the highest point in Africa, measuring almost 6,000 meters. The mountain supports 5 plant areas and many kinds of animals. The ice glaciers （冰川） on the mountain are disappearing very quickly. This will have a bad effect on the mountain's ecosystems（生态系统） and on Tanzania's travel industry. Also, a valuable record of thousands of years of weather history will also be lost if the ice melts.
Glacier National Park
In the United States, the icy blocks in Glacier National Park may soon completely disappear because of the weather change. In 1850, there were about 150 glaciers. By comparison, there are 26 glaciers remaining today. Scientists estimate that the glaciers will be gone by 2030. Warm temperatures are also threatening the many kinds of plants and animals that live in this mountain ecosystem.
Great Barrier Reef
The Great Barrier Reef in Australia is the largest coral reef（珊瑚礁）system in the world. Rising sea temperatures are greatly harming the reef. In some areas, healthy yellow, brown and green reefs have become white. The coral whitens when it is in warmer temperature. Sick or dying coral affects the whole ecosystem of this special underwater area, Water pollution and visits by careless swimmers and divers also threaten the reef.
