北京时间2022年7月21日，世界自然保护联盟（IUCN）更新濒危物种红色名录。名录显示，长江特有物种白鲟已经灭绝。白鲟作为一种起源于约2亿年前的鱼类，曾和恐龙在地球共存，也被古人大量记载，其体型硕大，可达七八米长。长江白鲟有着“中国淡水鱼之王”的称号。白鲟的灭绝给人类带来了什么警示？我们又该如何更好地保护其他珍稀的水生动物？

The International Union for Conrvation of Nature (IUCN) added the Chine paddlefish（白鲟）to its list of extinct species in July, 2022. People will never e a living Chine paddlefish again as it has been declared extinct. For many people in China, this may have been the first time they heard the name of the fish that was once a denizen（常客）of the Yangtze River Basin.
The fishcongo had lived in the Yangtze River Basin since about 200 million years ago. It was among the world’s biggest freshwater species and could grow up to 7.5 meters in length. Th
e last time the fish was spotted was in 2003 in the upper reaches of the Yangtze River in Yibin, Sichuan Province. It was an injured female sturgeon（鲟鱼）. After local people treated its wounds, it was relead into the river.
According to the IUCN, the global sturgeon reasssment found that all remaining 26 sturgeon species in the world are now at risk of extinction, up from 85 in 2009. Their decline over the past three generations is steeper than previously thought.
“The extinction of the Chine paddlefish should be a warning for everyone,” said Zhou Fei, China’s chief program officer at the World Wide Fund for Nature. “It has provided an opportunity for conrvation experts to rai public awareness about the urgency of protecting freshwater species in the Yangtze River Basin and educate the public on the need for more efforts to save other species living in the region from extinction,” he added.
To prevent further loss of freshwater species in China, people must act urgently. There is no time to waste. Also, long-term threats to their life and habitats must be green leafeliminated by taking systematic protection measures. The protection of biodiversity will delay the extinct
ion of some species. It’s not something that can be achieved by certain departments. Instead, it requires joint effects from all ctors of society.
