Chapter 104: A heavy show sign
While Yuan Yu was waiting in line to play with Tiger Palm, on the other side, Wang Jinxuan was in front of the glass curtain wall, admiring Jiaojiao's beautiful swimming.
The gigantic tiger body floats and sinks in the water, with its tail floating behind. When you turn your head, you can clearly see the white slender beards on both sides of the nose, and the yellow fur of the head appears in the sun. A layer of gold.
'S eyes looked at the tourists, and there was a majestic aura in the calm, which made several tourists utter exclamation and admiration.
Through the dark green water surface, she could still faintly see her limbs swaying under the water, suddenly slapped a piece of floating tree bark on the water to play, blinked her eyes to avoid the splashing water, and slapped the bark into the water. After that, the body swims forward gracefully.
Wang Jinxuan was a little excited to share her feelings, but looking back, Yuan Yu was still waiting in line.
The focus of admiring tigers was distracted a bit.
At this time, a huge science exhibition board hung on the wall between the two glass curtain walls, with a fierce look on it, and a roaring tiger attracted her attention, and she couldn't help walking up to see it.
"Tigers are the largest and most impressive big cats. They are powerful predators, with extraordinary power and agility…"
Next to there is a small picture, which is an introduction to the abilities of each part of the tiger!
When Wang Jinxuan saw the golden fur, Wang Jinxuan thought of a question she had never thought of before, and she was a little confused, yes, with such an eye-catching color, how did the tiger hunt?
"In the eyes of humans, the fur of tigers is golden yellow, but most mammals are red and color-blind, and the bright red-orange colors are not visible, including tigers' main prey, deer, horses, and sheep.
In their eyes, the golden fur and the color of the trees are almost the same, so tigers can hide near their prey with the camouflage of fur. "
"It turned out to be like this!"
Wang Jinxuan suddenly realized, and suddenly thought: "In this way, the red fur of the red panda is actually a disguise?"
These creatures have evolved amazingly.
Interest grew in her heart, and then she wandered around in the exhibition hall to watch other popular science exhibitions.
A very conspicuous display with the title "Why protect tigers?"
In fact, Wang Jinxuan can think of one thing. When she was in high school biology class, she said that producers, consumers, decomposers have their own roles, and a complete ecosystem is indispensable for any of them.
But understanding is limited to this.
"The tiger lives in the forest. It is a pure carnivore and the king at the top of the food chain.
mainly preys on wild boars, wild deer, wild sheep and other plant-eating animals, controls the number of these plant-eating animals, and also maintains the vegetation of the forest.
If there are no predators like tigers in the forest, it will trigger a series of chain reactions.
The plant-eating animals lack natural enemies to check and balance, and their numbers are increasing rapidly. As a result, the plants in the forest are eaten on a large area, and other animals or plants that live on these plants in the forest will also be affected.
Finally, the plant-eating animals that flooded will suffer severe damage due to disease and hunger, and the entire forest ecosystem will collapse.
Now we can see more and more news that wild boars are flooding, eating crops and even harming humans. In fact, it is caused by the lack of tigers' predation.
Protecting a tiger can keep the forest ecosystem in its territory in a healthy and balanced state.
A healthy forest can purify the air, clean the water source, and prevent landslides and mudslides.
Unhealthy forests may cause animal diseases, and unhealthy animals will also promote zoonotic diseases.
According to a research survey in South America, in some key ecological corridors where jaguars often appear, the chance of local people suffering from AIDS and avian flu has decreased.
These big cat predators can control disease outbreaks caused by herbivores, thereby preventing the leakage of diseases to humans.
If the work of protecting tigers is done well, it will not only benefit tigers, but also forests and other animals, as well as our own human beings. "
Wang Jinxuan was a little in awe of the tiger. It turns out that the tiger is not only powerful and beautiful, but also plays such an important role in the ecosystem. It is not an exaggeration to be called the patron saint of the forest.
Originally, she only liked cute things like red pandas and didn't have any special feelings for tigers, but now she suddenly likes tigers a little bit. The two likes are not the same, but the tiger is more of admiration!
Protect animals and protect nature. Green mountains and green waters are the golden mountains and silver mountains. I have heard such words many times, but there is always no actual feeling.
Some people may even think that humans have evolved into the hegemon of the earth because they can dominate other creatures at will?
Tigers, leopards, wolves, these animals are a scourge! Do not kill clean, but still coexist with them?
The earth is the territory of mankind. How can these disobedient beasts survive?
It's best to catch them all in the zoo circus, just let them be a plaything to watch, perform a fire-jumping or something, just to show the prestige of human beings.
This lack of respect for nature and the supreme arrogance of mankind has led to many serious disasters.
The increasing number of emerging viruses is largely the result of ecological destruction and wildlife trade.
As humans invade the wild environment, the risk of new epidemics has greatly increased.
However, many people still haven't realized this.
This attitude is like a child waving a torch, playing in the house where he lives, and seeing the pillars being burned, he is very happy, but when the fire is big and the house collapses, he realizes that something is wrong, crying and regretting the original It's too late.
Wang Jinxuan took another two steps and looked at the sign "The Status of the Tiger" next to her.
" About 2 million years ago, tiger originated in central China.
Among the eight tiger subspecies, the Bali tiger, the Caspian tiger and the Java tiger became extinct one after another.
The only remaining Siberian tigers, South China tigers, Indochinese tigers, Bengal tigers and Sumatran tigers.
A hundred years ago, there were more than 100,000 wild tigers roaming in the wilderness, but now it has dropped to less than 4,000.
The total number of existing wild tigers in our country is less than 100. (Optimistic estimate, conservatively less than 30
Wang Jinxuan was taken aback by this shocking number, her eyes widened in disbelief: "Is there only so many tigers left?"
I just learned that the tiger is the protector of the forest. It turns out that the protector has fallen.
"South China tiger, the ancestor of all tiger subspecies, also called Chinese tiger, is a unique tiger subspecies in China.
The South China Tiger is actually not limited to South China, it once spread throughout North China, East China and Central Plains.
Due to human activities and hunting, its habitat has shrunk sharply to southern China, and it was named the South China Tiger. Its preciousness far exceeds that of giant pandas.
At the time of the founding of the People's Republic of China, there were 4,000 South China Tigers. In just 20-30 years, there were 40 tigers, a decrease of 99%.
After 1986, people saw a live South China tiger in Anren, Hunan for the last time. Since then, there has been no exact record of a wild South China tiger. Only a few captive tigers are lingering in the zoo.
Fewer than fifty South China tigers raised by zoos across the country have severely degraded their vital characteristics due to inbreeding for many generations.
From a biological theory, a species whose population is less than one thousand in number is unlikely to reproduce naturally.
The heavy lines on the popular science exhibition board made Wang Jinxuan sigh deeply.
