Unnoticed and unappreciated for five decades，a large female turtle （龟）with a stained（彩色的），leathery（粗而硬的） shell is now a precious commodity（物品）in Changsha’s old zoo．She is fed on a special diet of raw meat．Her small pool has been covered with glass which can defend it from bullets．A special camera monitors her movements．A guard is posted at night．
The purpose is simple：the turtle must not die．
Earlier this year，scientists concluded that she was the planet’s last known female Yangtze giant soft shell turtle．She is about 80 years old and weighs almost 90 pounds．

“It’s a very dangerous situation,” said Peter Pritchard, a famous turtle expert in the United States，who has helped try to save the species．、
For many Chinese people，the turtle is the symbol of health and long life，but the last two Yangtze giant soft-shell creatures show the threatened state of wildlife and biodiversity（生物多样性）in China．Pollution, hunting and over development are destroying natural habitats，and also endangering the plant and the animal population．
China contains some of the world’s richest treasures of biodiversity, yet the latest major survey of plants and animals shows a discouraging picture．Nearly 40 percent of all mammal species in China are now endangered, Scientists say．For plants，the situation is worse；70 percent of all nonflowering plant species and 86 percent of flowering species are considered threatened．
