【题目】 China says 16 endangered finless porpoises(江豚)have been found dead since the beginning of the year and experts blame water pollution and climate change for pushing the species toward extinction

The freshwater porpoise-popularly known in Chinese as the"river pig"-mainly lives in China's Yangtze River and two lakes linked to the river

Authorities(官方)have discovered 10dead porpoises in Dongting Llake in the central province of Hunan since March, according to a statement by the government of Yueyang City, which is located on the lake's shore Another six dead porpoises have been found in Poyang Lake in the eastern province of Jiangxi since the beginning of the year Experts warn that the species will be extinct within a matter of years

Wang Kexiong, a researcher at China's Institute of Hydrobiology, said water pollution, shipping and sand dredging(挖掘)were all possible contributing factors to the recent deaths

Many rivers in China have become heavily polluted with poisonous waste from factories and farms-pollution blamed on more than three decades of rapid economic growth and slow enforcement(实施)of environmental protection laws

The report said climate change also could be to blame as the dry weather has caused water levels to drop and makes it more difficult for the porpoises to find food Tests have shown that some of the porpoises are believed to have died of starvation(饥饿).

In 2006, China was estimated(估计)to have only 1,200 finless porpoises left That same year, the Baiji-a freshwater dolphin also native to the Yangtze River-was declared extinct Earlier this year, a survey found just 65"river pigs"in Dongting Lake and 300-400 in Poyang Lake
