Chapter 429 (1/2)

Of course, there is much to say about the story of the traveller pigeon.

Originally, Indians hunted with smoke. After the colonists learned it, they felt it was not efficient enough. They upgraded this method and burned it directly with sulfur.

Pigeons like to hold together to deal with threats. There may be tens of millions of pigeons living in a forest. Hundreds of thousands of pigeons can fall down once smoked with sulfur.

In a record of Audubon, hunters rounded up a 300 square kilometer habitat of passenger pigeons, poisoned passenger pigeons landed like snowflakes, and even crushed the carriages used to carry the bodies of passenger pigeons.

Two farms rushed their pigs from more than 100 kilometers away to feast them.

Another hunter came up with a way to sew the eyes of a passenger pigeon, tie a rope to a branch and set up a net around it.

After hearing the news, the companion of the traveling pigeon thought there was food nearby, so they fell into the net one after another, and thousands of them could be caught in one net. This kind of traveling pigeon used as bait is called ”medium pigeon”.

However, there are too many contents on the outdoor display board, and tourists may be too lazy to read it.

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

The story of the extinction of the traveller pigeon has a great impact. Liu Wei has also heard of it!

But I just know about it. It seems that there are a lot of them because of the extinction of human beings.

I learned these details for the first time and stared in shock: ”5 billion? Extinction in a century and a half? ”

The two accompanying pictures of the exhibition card, the traveler's pigeon like a dark cloud in the sky and the lonely traveler's pigeon with only one left, also caused a great impact on him.

What is the concept of 5 billion? It seems that human beings are only more than 7 billion.

It's a little scary to think about this. I usually live in peace of mind. I have known about the hole in the ozone layer, global warming and environmental degradation since I was a child. I can often do it on reading questions, and writing compositions is also classic material.

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

If there is any huge crisis, such as fatal infectious diseases, nuclear waste water and nuclear war, how long can mankind live?

Will it disappear quickly at some point in the future, just like a traveler's dove?

No, no, it's terrible! A little flustered at the thought.

In front of the exhibition board of the passenger pigeon, some people were silent, sighed slightly, some frowned, thought intently, some left at a glance, and children stroked the low passenger pigeon statue with laughter.

The monitor clapped his hands: ”let's go. Let's not look at pigeons. Let's go to see giant pandas. I checked the strategy before and said that pandas are the most active at eight or nine in the morning! If you go later, you may have a rest. ”

”Oh!” Everyone cheered and agreed.

……

Come to the giant panda museum!

Although Liu Wei saw the appearance of the giant panda museum when he watched the news before.

But at the moment, I couldn't help but wonder: ”Wow, this exhibition hall is so beautiful!”

”It's really beautiful! Compared with the zoo here, the environment of my zoo is really the same as that of the pigsty. I thought the zoo was like that! ” Some students were stunned and their world outlook was subverted.

In spring, plants grow and everything recovers!

The temperature gradually warmed up, the hot and humid air from the ocean began to be active, and there was a light rain two days ago.

The sunshine in the past few months was calm and cold. Now it is warm and bright, with a layer of soft gold.

The blue of the sky seems to become clearer.

After the rain, the plants and trees in the exhibition hall draw out fresh buds with the rising of Yang, and vitality begins to germinate.

Such a comfortable weather, Zhuang Zhuang also looks very comfortable!

Lying on her side on the green lawn, she pillowed one of her claws on her face, and her two black hind legs overlapped. Her posture was quite enchanting, like a drunken imperial concubine!

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

Or simply in a daze.

Yang Yue is like a child. She smiles sweetly and happily. Her eyes are full of excitement and some are incredible!
