While Yuan Yu was waiting in line to play the tiger handheld machine, on the other side, Wang Jinxuan was in front of the glass curtain wall, admiring the beautiful posture of Jiaojiao's swimming.

The huge body of the tiger floats and sinks in the water, the tail floats behind, and when it turns its head, the white slender beard on both sides of the nose can be clearly seen, and the yellow fur of the head glows with a layer of gold in the sunlight.

The eyes looked at the tourists, and there was a majestic momentum in the calm, which made several tourists can't help but let out a voice of exclamation.

Through the dark green and swarthy water, she could faintly see her limbs moving underwater, suddenly slapping a floating bark on the water to play, blinking her eyes to avoid the splash, and after slapping the bark into the water, her body swam forward gracefully.

Wang Jinxuan was a little excited and wanted to share her feelings, but when she looked back, Yuan Yu was still queuing.

The attention that had been focused on admiring the tiger was somewhat distracted.

At this time, a huge popular science display board hung on the wall between the two glass curtain walls, on which a fierce tiger with a fierce eye and roaring attracted her attention, and she couldn't help but walk up to look at it.

"Tigers are the largest and most formidable big cats, they are powerful predators, and they are extremely powerful and agile ......"

There are also small pictures next to it, on which are the abilities of each part of the tiger!

When she saw the golden fur, Wang Jinxuan thought of a question that she had never thought of before, and she had some doubts in her heart, right, how did tigers hunt with such an eye-catching color?

"In the eyes of humans, the tiger's fur is golden yellow, but the vast majority of mammals are red color blind and cannot see the bright red and orange colors, including the tiger's main prey, deer, horses, sheep, etc.

In their eyes, the golden fur is almost the same color as the trees, so the tiger can use the camouflage of its fur to lurk near its prey. ”

"I see!"

Wang Jinxuan suddenly realized, and suddenly thought again: "So it seems that the red fur of the red panda is actually a kind of camouflage?" ”

These creatures have evolved wonderfully.

Her heart became intrigued, and then she wandered around the pavilion to watch other popular science signs.

A prominently placed sign with the title "Why Protect Tigers?" ”

In fact, Wang Jinxuan can think of one point, I said in biology class in high school that producers, consumers, and decomposers all have their own roles, and a complete ecosystem is indispensable for any of them.

But that's all there is to it.

"Tigers live in the forest, they are pure carnivores, kings at the top of the food chain.

It mainly preys on wild boars, wild deer, wild sheep and other herbivores, controls the number of these herbivores, and also maintains the vegetation of the forest.

If there are no predators like tigers in the forest, it will set off a chain reaction.

The lack of natural predators and the rapid growth of herbivorous animals have led to the widespread devouring of plants in the forest, as well as the impact on other animals or plants that depend on these plants in the forest.

Eventually, the overrun of herbivores will be devastated by disease and starvation, and the entire forest ecosystem will collapse.

Nowadays, we can see more and more news of wild boars overflowing, gnawing on crops and even harming humans, which is actually due to the lack of predation by tigers.

Protecting a tiger can keep the forest ecosystem in its territory healthy and balanced.

Healthy forests purify the air, clean water, and prevent landslides and mudslides.

Unhealthy forests can cause disease in animals, and unhealthy animals can also contribute to zoonoses.

According to a study in South America, the local population has a reduced incidence of AIDS and avian influenza in some of the key ecological corridors where jaguars are frequented.

These big cat predators can control disease outbreaks caused by herbivores, thus preventing the disease from leaking into humans.

If we do a good job of protecting tigers, it is not only the tigers that will ultimately benefit, but also the forests and other animals, as well as us humans. ”

Wang Jinxuan was a little in awe of the tiger, it turned out that the tiger is not only powerful and beautiful, but also plays such an important role in the ecosystem, and it is not an exaggeration to call it the guardian saint of the forest.

Originally, she only liked cute things like red pandas, and she didn't have any special feelings for tigers, but now she suddenly likes tigers a little. The two likes are not the same, and the tiger is more admiration!

Protecting animals and nature, green mountains and clear waters are invaluable assets, I have heard such words many times, but there is no actual feeling.

Some people even think that human beings have evolved to become the overlord of the earth just to be able to dominate other creatures at will.

Tigers, leopards, wolves and other animals are a scourge! Don't kill clean, but still coexist with them?

The earth is the territory of human beings, how can there be room for these disobedient beasts to live?

It's best to get all of them into the zoo circus, and let them just be ornamental playthings, perform a fire ring or something, so as to show the majesty of human beings.

This lack of respect for nature, the supremacy of human beings, has led to many serious disasters.

The growing number of emerging viruses is largely the result of ecological destruction and wildlife trade.

With the invasion of humans into the wild, the risk of new epidemic outbreaks has increased dramatically.

However, there are still many people who have not yet realized this.

This attitude is like a child waving a torch and lighting a fire in the house where he lives, and he is very happy to see the pillar being burned, but when the fire burns and the house collapses, he realizes that something is wrong, and it is too late to cry and regret the mistake.

Wang Jinxuan took two more steps and looked at a sign next to her, "The Current Situation of Tigers".

"About 2 million years ago, tigers originated in central China.

Among the eight tiger subspecies, the Balinese tiger, the Caspian tiger and the Javan tiger have become extinct.

Only Siberian tigers, South China tigers, Indochinese tigers, Bengal tigers and Sumatran tigers remain.

A hundred years ago, more than 100,000 wild tigers roamed the wilderness, but now there are fewer than 4,000.

The total number of wild tigers in China is less than 100. (Optimistically, conservatively less than 30)"

Wang Jinxuan was shocked by this shocking number, and her eyes widened in disbelief: "Is there only such a tiger left?" ”

Just now I learned that the tiger is the protector of the forest, and it turns out that the protector has fallen.

"The South China tiger, the ancestor of all tiger subspecies, is also called the Chinese tiger, which is endemic to China.

The South China tiger is not actually confined to South China, it has been found in the northern, eastern and central parts of China.

Due to human activities and hunting, its habitat has shrunk sharply to South China, and it is named South China Tiger. It is far more precious than the giant panda.

At the time of the founding of the People's Republic of China, there were still 4,000 South China tigers, but in just 20-30 years, the number has increased to 40, a decrease of 99 percent.

After 1986, the last time a live South China tiger was seen in Anren, Hunan Province, there has been no definite record of a South China tiger in the wild. Only a handful of captive tigers survive in zoos.

Fewer than 50 South China tigers raised in zoos across the country have been severely degraded due to multi-generational inbreeding.

Theoretically speaking, if the population of a species is less than 1,000, the possibility of natural reproduction is very small.

……”

The heavy words on the popular science display board made Wang Jinxuan sigh deeply.
