I Have a Safari Park - Chapter 709

Linhai TV!

The host said: “Dear audience friends, good morning! This is the Linhai hotline. We focus on the hot social topics that everyone cares about most.

The content of this issue is, under the epidemic situation, what kind of relationship does the virus have with wild animals? How should we treat the wild animals around us? This is an issue related to everyone’s health and safety, as well as the ecological safety of society.

Today, we also specially invited two very heavyweight guests in related fields to answer questions. One is Fang Ye, the director of our Linhai Zoo, and the other is Professor Wang Yan, a researcher from Xinghe University. Welcome! “

The host moved towards Fang Ye on the sofa, Wang Yan stretched out his hand, both of them nodded in response.

Due to the epidemic, fewer people went out to play, and everyone stayed at home on weekends.

Either watching the phone or playing on the computer, or watching TV.

Liu Xueqing’s house.

Yingying was playing with building blocks on the ground. Grandpa Yingying was sitting on the sofa and watching TV. Liu Xueqing looked at the phone!

I was discussing with my colleagues when the new crown could pass, and when I heard the news, I immediately raised my head.

Put down the phone, call Yingying’s father over, looking at the TV intently.

This is exactly what she cares about!

The host also said: “You can edit text messages and ask questions on your mobile phone to interact with our experts on the spot.”

Then facing Fang Ye and Wang Yan, he asked: “Recently, everyone has been worried about the new crown. There are many questions about wild animals, such as whether this crayfish can be eaten, whether this Brazilian tortoise can be raised, and the community. The bats that appeared may have many friends who were frightened by the bats that appeared at home or near the community. Can they be killed?”

Fang Ye was rather helpless to mention this: “The staff at our zoo are really busy recently. They go to various communities to help everyone drive away bats. I can feel that everyone has an extreme fear of bats. If you shout and kill, you must get rid of them. Die, don’t worry about it.”

Wang Yan continued: “Not only Linhai, we found that many big cities have panic about bats.

In fact, whether bats can be killed is not the most important issue. Which animal is the intermediate host and whether they can eat is not an important issue. They are not the core of the problem.

I think there are several points reflected. The first is that everyone is too ignorant of wild animals; the second is that we are at a loss as to the fact that wild animals will appear in the city, and that wild animals will inevitably appear; Third, even if most people like wild animals, their understanding of animals cannot rise to the level of the ecosystem. “

In fact, the ecosystem is a whole, which affects the whole body. Some experts have proposed that the concept of ecological extermination is not new in history. Killing bats or something similar to killing bats has appeared on many continents.

Like a prairie dog! It is a very common grassland animal in North America.

People today know a lot about the prairie dog, for example, it speaks, can make words, and has a very rich language system.

Even if you give it something you have never seen before, such as a mobile phone and a few prairie dogs together, you can create a word like mobile phone with a single thought, and you can also stabilize the word like mobile phone in the group. Pass it on.

But more than a hundred years ago, people’s evaluation of it was overwhelming, and the grasslands were full of useless creatures. In fact, people are used to evaluating whether an animal is useful or not. I think this is an idea rooted deep in our hearts.

People think that after the prairie dogs are killed, without them eating grass, the pastures may become better, which is more conducive to grazing, which can increase the output of livestock.

In 1974, large-scale poisoning of prairie dogs began. With the combined effects of poisoning, gun killing, filling caves, using dogs, and various methods, the number of prairie dogs declined in many places. 98. Some places have been killed.

As a result, people were surprised to find that the grass grows faster after the prairie dog grazes the grass for the first time, and the newly grown parts, protein, sugar, and various nutrients are more comprehensive. And where there are prairie dogs, where they constantly turn the soil, the species composition of the grassland is more abundant, but it is a healthier grassland.

From the American bison to the pronghorn, everyone depends on the prairie dog to survive.

So since then, people have gradually realized that there are key species in the ecosystem, the concept of cornerstone species. But later, such errors continued to continue. “

Fang Ye nodded and said, “People who usually visit our zoo and have been to the plateau animal exhibition area, or usually like Tibetan foxes and rabbits. Watching the documentary, you will know that their favorite food is pikas! Same as the little mouse, but without a tail.

The pika is like the rice on the plateau. Everyone bullies it.

The fate of pikas is similar to that of prairie dogs. People think that pikas have promoted the desertification of pastures. Large-scale poisoning and killing have caused many common buzzards and raptors such as big buzzards to eat poisonous pikas and die.

Through long-term monitoring, people have discovered that the grassland without pikas has not only not improved, but has become worse. Because pikas dig holes to increase the water permeability and air permeability of the soil, where there are no pikas, water can’t penetrate, but it will cause soil erosion.

The grass grows too high, pikas cannot see their natural enemies, so they like to live in places where the grass is relatively short and sparse. It is not the desertification they cause. “

Wang Yan said: “Every large-scale killing of these creatures often fails, and will lead to the opposite result. People have changed the ecosystem in a whimsical way, and then they need to pay many times more than the killing. It changed back to its original appearance.

There is only one situation that needs to be killed. UU Reading www.uukanshu.com is an invasive species. “

Fang Yedao: “In the natural ecosystem, every biological existence has its meaning.”

The host said: “Hey, that said, I think of a wild boar! I broke into the milk tea shop before and was caught by your zoo, right?”

Fang Ye smiled and said, “The milk tea wild boar has been released.

Indeed, the wild boar is also an animal that is often misunderstood.

In recent years, there has been a lot of news about wild boars entering the city. The impression given by the news is that wild boars have become very popular, and they are pests, ruining crops, and possibly hurting people. We need to eliminate them.

In fact, wild boars play an important role in forests. They like to hunt for food. In this process, the litter, air, and soil are mixed together to decompose into humus faster, and the seeds can germinate better, which helps the succession of the forest.

When it snows in winter, it can also pave the snow away so that small mammals such as birds and squirrels can forage. “
