Experts found that ducks kissed fish 4 1 10,000 years ago. So far, how many species have gone extinct on the earth?

So far, many species on the earth have become extinct. I know the famous extinct animals are dodo, china rhino, Taiwanese clouded leopard and so on. In addition, the Chinese alligator, Yunnan golden monkey, wild golden monkey, Baiji dolphin and giant panda in China are endangered species, and their numbers are limited, so we need to protect them.

Next, let's talk about the introduction and extinction of dodo, china rhino and Taiwanese clouded leopard.

I. Duoduo

Although the dodo is extinct, it is still the national bird of Mauritius. The dodo looks a bit like a big duck. Its feathers are blue-gray, its wings are short, it can't fly, its legs are thick and yellow, and there are a bunch of curled feathers on its hips. It is very big, weighing 23 kilograms, but each nest lays an egg. In the past, dodos lived a leisurely life on the island of Mauritius. The dodo, which lacks escape skills, is huge, delicious and has poor reproductive ability. Once it meets a large number of natural enemies, it will die. After the Portuguese and later Dutch came to Mauritius, they established a maritime trade route, and the nightmare of the dodo began. They were slaughtered in large quantities for human consumption, and animals such as dogs and pigs brought by these foreign colonists began to prey on dodos with poor counterattack ability. The dodo became extinct without any doubt.

Second, china rhino.

China rhino was once widely distributed in most of China, mainly inhabited in mountainous areas near the edge of forests, and also became extinct in 1950s. The extinction of china rhino is related to the decrease of habitat temperature. Around 500 BC, the climate north of the Yellow River became obviously cold. Its last habitat is in Yunnan, China, and the reproductive capacity of china rhino is also very poor. It only gave birth to one child in two years. In addition, in ancient Chinese medical books, rhinoceros horn is a precious Chinese herbal medicine for clearing away heat and cooling blood, and its skin and blood can also be used as medicine, which also caused china rhino to be hunted and killed in large numbers and eventually become extinct.

Third, Taiwan clouded leopard

In Taiwan Province Province, China, there is a very beautiful cat, the Taiwanese clouded leopard. Taiwan clouded leopard is a subspecies of clouded leopard, with cloud stripes on both sides of its body. Moreover, the canine-to-tooth ratio of clouded leopard is the longest among all cats. Although its average body length is only about 80 cm (excluding its tail), the clouded leopard can climb trees like monkeys to kill primates with its flexible body and sharp canine teeth. Because the stripes of the clouded leopard are beautiful, its fur has been targeted by some lawless people. Since19th century, human beings have never stopped poaching clouded leopards until 1972, when the last clouded leopard in Taiwan died at the gunpoint of poachers.

Protecting wild animals is actually protecting human beings themselves. Don't quench your thirst by drinking poison.
