The white sturgeon, like the Yangtze River Chinese sturgeon, is one of the very few ancient fishes that have survived from the Mesozoic Cretaceous period dating back 150 million years. This ancient species once carried 100 million years and 5,000 years of vicissitudes, witnessed the demise of dinosaurs and several environmental changes, witnessed the emergence and rise of the entire human race, but finally failed to enter 2020 and became a victim of human development. In the movie "The Wandering Earth", it was said: At first, no one cared about this disaster, it was just a wildfire, a drought, the extinction of a species, the disappearance of a city... Until this disaster is relevant to everyone.
The so-called "thousand pounds of wax, ten thousand pounds of elephants." "Lazi" refers to the Chinese sturgeon, and "elephant" refers to the Yangtze River white sturgeon, which is said to grow up to tens of thousands of pounds. The white sturgeon is large, the adult fish can be up to seven or eight meters long, swimming fast, known as the "tiger in the water" and "the king of China's freshwater fish", it is also one of the world's ten largest freshwater fish.
For years, the Yangtze River white sturgeon has not been seen in the painstaking search of fishermen and scientists. According to previous reports, in early 2003, scientists rescued a Yangtze River white sturgeon, released it and tracked it. But because the tracking ships hit the reef, the white sturgeon that were released also disappeared. No one could have imagined that this would be the last time people would find the Yangtze River white sturgeon. The loss of this one fish also loses the entire species.
Under the rapid and extensive economic development model of the past few decades, the Yangtze River Biocomposity Index has reached the worst "fish-free" level. Therefore, it is imperative to achieve a ban on fishing and let the Yangtze River recuperate.
In addition to the extinction of the Yangtze River white sturgeon, the Chinese sturgeon and Yangtze River sturgeon, which are endemic to China, are still assessed as "critically endangered" by the International Union for Conservation of Nature (IUCN). In 2017 and 2018, the Ministry of Agriculture and Rural Affairs successively launched the "Chinese Sturgeon Rescue Action Plan" and the "Yangtze River Sturgeon Rescue Action Plan". The Yangtze River is an important ecological treasure house in China, with more than 4,000 species of aquatic organisms distributed, and is one of the rivers with the richest aquatic biodiversity in the world. In the "Directory of Wild Animals under National Key Protection" approved by the State Council in 1988, there are 9 species of fish in the Yangtze River Basin, namely the first-class protected animal white sturgeon, the Chinese sturgeon and the Yangtze River sturgeon.
Ancient people's clouds: a few poppies do not enter the pond, fish turtles are invincible, but due to overfishing, the Yangtze River has fallen into a "fishless" situation. Fish should be released, and people should reflect. Exhaustion and fishing is no fish, respect for the law is no worry, the rise and fall of fish, the essence is nature for the development of the light of the light. Give the Yangtze River a rest period, the Yangtze River can return the world to life.
Due to some discordant human behavior, such as car exhaust emissions, landfills, large-scale deforestation... These acts of facilitating human life will cause global warming, and according to the British "Guardian", global warming may be the cause of the largest species extinction event in the history of the earth - the third mass extinction. Don't wait until the species goes extinct. We know that we have no time to do anything about the extinct individual white sturgeon. But for those endangered animals that still exist, we should start small, reduce environmental pollution, and protect the environment on which wild animals live. Don't let our offspring only see these cute animals in photos!
