Of course, there is much more to be told about the story of the passenger pigeon.

Originally, the Indians used smoke to hunt, but after the colonists learned it, they felt that it was not efficient enough, so they upgraded this method and burned it directly with sulfur.

Passenger pigeons like to huddle together to deal with threats, and a forest may be inhabited by tens of millions of passenger pigeons, and hundreds of thousands can fall down after a single sulfur smoke.

In one of Audubon's accounts, hunters rounded up a 300-square-kilometre herd of passenger pigeons, and the poisoned passenger pigeons fell to the ground like snowflakes, crushing even the wagons used to carry the carcass.

Two farmers simply drove their pigs from more than 100 kilometers away to feed the herd.

There are also hunters who come up with a way to sew the eyes of a passenger pigeon, tie it to a branch with a rope, and set up a net around it.

When the companions of the passenger pigeon heard the news, they thought that there was food nearby, so they fell into the net, and they could catch thousands of them in one net. This passenger pigeon, which is used as bait, is called a "matchmaker".

However, there are too many contents on the outdoor display boards, and tourists may not be too lazy to read them.

So just a brief introduction to the process of the extinction of the passenger pigeon.

The story of the extinction of the passenger pigeon has a huge impact, and Liu Wei has also heard about it!

But I just know a rough idea, it seems that there are a lot of them, because of the extinction of human hunting.

Knowing these details for the first time, his eyes widened in shock: "5 billion? A century and a half of extinction? ”

The two pictures of the exhibition board, the passenger pigeon like a black cloud in the sky, and the lone passenger pigeon, also caused a great impact on him.

What is the concept of 5 billion, it seems that there are only more than 7 billion human beings.

It's a bit scary to think about it like this, but I usually sit back and relax, and I have known about the hole in the ozone layer, global warming, and environmental degradation since I was a child, and I can often do it on reading questions, and writing essays is also classic material.

I only know that I mention it every year, and it gets worse every year, and I haven't felt anything about it, and I always feel that it's something far away from me.

If there is really some huge crisis, deadly infectious diseases, nuclear wastewater, nuclear war, how long will humanity live?

Will it disappear like a passenger pigeon at some point in the future?

No, no, it's scary! I panicked a little when I thought about it.

In front of the passenger pigeon's sign, some people are silent and sigh slightly, some frown and think, some glance and leave, and some children laugh and stroke the statue of the passenger pigeon in the lower place.

The squad leader clapped his hands: "Let's go, let's go, let's stop looking at the pigeons, let's go see the giant panda, I checked the strategy before, and said that the panda is the most active at eight or nine o'clock in the morning!" If you go late, you may have a rest. ”

"Oh!" The crowd cheered and agreed.

……

Come to the Giant Panda Pavilion!

Although Liu Wei saw the appearance of the Giant Panda Pavilion when he watched the news before.

But at this moment, I couldn't help but exclaim: "Wow, this pavilion is so beautiful!" ”

"Beautiful, indeed! Compared to this side, the environment of my zoo is really the same as a pigsty, I thought zoos were like that! Some students were dumbfounded, and their worldview was subverted.

In spring, plants and trees grow, and everything recovers!

The temperature is gradually warming, the hot and humid air from the sea is starting to come active, and there was a light rain two days ago.

The sun had been calm and cold for the first few months, but now it is much warmer and brighter, with a soft golden tinge.

The blue of the sky seems to have become clearer.

After the rain, the plants and trees in the exhibition hall draw out fresh shoots with the rising yang energy, and vitality begins to sprout.

With such a comfortable weather, it looks very pleasant!

Lying on his side on the green lawn, with one of his paws on his face, and his two black hind legs overlapped, his posture was quite enchanting, like a drunken concubine!

Looking at a stone in the distance, I don't know what to think about!

Or just a daze.

Yang Yue was like a child, smiling sweetly and happily, her eyes were full of excitement, and there was some disbelief!

Turning his head to look at Jiang Lan's expression, he exchanged glances, as if to say, "What a panda!" ”

This is followed by a string of "hey, hey, hey, hey" chuckles!

Everyone admired the pandas with relish, and some took pictures with their mobile phones!

Zhuang Zhuang was in a daze for a moment, one arm was raised, stretched out to the sky, his leg also moved, his right leg was half bent, and he grinned and rubbed his belly with his heel.

Rubbing and rubbing, the body gradually changed from lying on his side to lying on his back, his right foot scratching his belly and the base of his leg, his raised arm swaying with the tickling, and his left foot did not know when it was up.

Looking at it like this, it should be very pleasant!

Everyone couldn't help but laugh: "Haha, it's so cute." ”

"It's so rhythmic!"

"Swing Swing, Let's Swing Together!"

After scratching the itch, the strong limbs fell back to the ground, rolled over and got up.

Slowly twisting his buttocks, he began to patrol the exhibition hall with his inner figure.

Walking to the place close to the glass curtain wall, everyone suddenly waved to Zhuang Zhuang excitedly!

"Wow, the panda is coming!"

Wu Jiancong put his palm on the glass: "Panda Panda, let's give us a high-five!" ”

It was still very visually striking to see a big bear with a wide body and a fat body, black and white color, picking up small bushes, stepping on a wide black bear paw from the hillside, and walking towards him calmly!

Zhuang Zhuang didn't even see them at all.

Originally, the eyesight was not good, and the light in the corridor was still darker than the exhibition area, which was a natural light barrier.

Unless you are a meter or two away from the glass curtain wall, you can see what is going on inside.

Gradually, they walked farther away and came to a tall tree.

I found a sack, and immediately leaned in and sniffed it with great interest.

The sack was hung from a stout trunk with springs and ropes, and contained some bamboo leaves.

Strong and strong are in interest!

The man stood up, hugged the sack, and bit the sack firmly with his mouth.

Then he spun around and lay on his back on the grass!

Holding the sack and swaying from side to side.

Because of the spring added to the place where the sack is tied, the toughness of the sack is very good!

I was dragged to the ground, and the spring was pulled, and I felt like I was jumping up.

Zhuang Zhuang hugged the sack tightly, as if he was wrestling with a very strong opponent and practicing boxing!

Hey! Ha!

Shaking around, sharp teeth tore at the sack, and soon the sack was bitten into a thousand holes.

But Zhuang Zhuang is not very hungry, more playing.

After playing twice, I felt a little tired, and I didn't want to work so hard, so I let go of the sack and walked away slowly with my buttocks.

Liu Wei saw the docent in front of him wearing work clothes, and a circle of tourists around him, who seemed to be explaining something, so he also leaned over.

I saw that the narrator was wearing a glove, holding a green round strip in his hand, and said with a smile: "Who else wants to smell it?" ”

Liu Wei couldn't help but have a bad thought, raised his hand and asked, "Uh...... What is it? ”

The narrator smiled kindly: "Panda feces, are you interested in smelling it?" ”
