On July 2, 2022, a sad news came. IUCN updated the red list of endangered species. According to the list, paddlefish, a species unique to the Yangtze River, became extinct. The news appeared on the Internet. You know, the white bear is one of the few ancient languages left over from the Cretaceous period1.500 million years ago. And only China has found it in the world, so it is also known as the Yangtze River paddlefish, which is mainly distributed in the Yangtze River basin and has high academic research value. However, it is such a long-lived fish that has lived for hundreds of millions of years, but it has disappeared in human society. Bai Xun's last appearance was on the New Year's Day in 2003. At that time, an expert from the Yangtze River Fisheries Research Institute and the president of China Fisheries Research Institute saved a white sturgeon in Sichuan, which was also man-made. There are many endangered sturgeons in the Yangtze River basin. 1 This number is Acipenser sinensis, an ancient and rare fish unique to China. It is a national first-class protected animal and has the reputation of giant panda and living fossil in the water. However, in recent years, the institute has not monitored the natural spawning of wild Chinese sturgeon in the Yangtze River, and its survival challenge is not optimistic. The second is the baiji, also known as the giant panda in the water. Baiji dolphin is a small cetacean living in the middle and lower reaches of the Yangtze River, but its population began to decline sharply in 1980s, and it was listed as a protected animal in China on 1983. 1986, national statistics show that the number of whales is less than 300. In 2007, the functional extinction of baiji was officially announced on the biological stationery of the Royal Society. Facing the extinction of fish, Bian Xiao wants to show that protecting the earth means protecting human beings. China's freshwater fish, the Wang Changjiang white sturgeon, has been officially extinct, so which species will be extinct next? How do we bring them back to life? I hope that the Yangtze sturgeon can be downgraded and return to the rivers and seas as soon as possible.
