I Have a Safari Park

Linhai TV!

The host said: "Dear audiences, good morning everyone! This is "Linhai Hotline", we focus on the social hot topics that everyone cares about most.

The content of this issue is, under the epidemic, what is the relationship between the virus and wild animals? How should we treat the wild animals around us? This is an issue related to the health and safety of everyone and the ecological safety of society.

Today, we also specially invited two very important guests in related fields to answer, one is Fang Ye, the director of our Linhai Zoo, and the other is Professor Wang Yan, a researcher of Galaxy University. Welcome! "

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

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

It's not watching the phone and playing on the computer, it's watching TV.

Liu Xueqing's house.

Yingying is playing with building blocks on the ground, Grandpa Yingying is sitting on the sofa watching TV, and Liu Xueqing is looking at her phone!

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

Put down the phone, call Yingying's dad over, and look at the TV intently.

This is exactly what she cares about!

The host added: "You can edit text messages on your mobile phone, ask questions, and interact with our experts on the spot."

Then he faced Fang Ye and Wang Yan and asked: "Everyone has been worried about the new crown recently. There are many questions about wild animals, such as whether this crayfish can still be eaten, whether this Brazilian turtle can be raised, and in the community. The bats that appear may have many friends, and they are all frightened by the bats that appear at home or near the community, can they kill them?"

Fang Ye was quite helpless when he mentioned this: "The staff of our zoo are really busy recently. They went to various communities to help everyone drive away bats. I can feel that everyone has an extreme fear of bats. Don't worry if you don't die."

Wang Yan continued: "Not only in Linhai, we found that some other big cities have also recently experienced panic about bats.

In fact, whether bats can kill is not the most important issue. Which animal is the intermediate host, and whether it can be eaten or not is not an important issue. They are not the core of the problem.

I think it reflects a few points. The first is that people really don’t know much about wild animals; the second is that we may be confused about the fact that there will be wild animals in cities, and wild animals will inevitably appear; Third, even most people who like wild animals have no way of understanding animals to the level of ecosystems.

In fact, the ecosystem is a whole, and it affects the whole body. Some experts have proposed that the concept of the so-called ecological killing is not a new thing in history. Killing bats or something similar to killing bats has occurred on many continents.

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

People today know a lot about the prairie dog, such as it speaks, can create words, and has a very rich language system.

Even if you give it something it has never seen before, such as a mobile phone, a few prairie dogs and mice get together, and after thinking about it, you can create a word like 'mobile phone', and you can also put words like 'mobile phone' in It is passed down steadily in the group.

But more than a hundred years ago, people's evaluation of it was overwhelming, and the grassland was 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 in our hearts.

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

In the 1940s, large-scale poisoning of prairie dogs and rats began. Poisoning, shooting, watering caves, using dogs, and a combination of various methods, the number of prairie dogs in many places declined. 98%, some places were killed.

As a result, people were very surprised to find that after the prairie dogs gnawed on the grass for the first time, the growth of the grass would become faster, and the newly grown parts had more comprehensive protein, sugar and various nutrients. 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 bison to pronghorn, everyone depends on prairie dogs for survival.

So from that time, people gradually realized that there are key species in the ecosystem, the concept of cornerstone species. But later, such mistakes continued. "

Fang Ye nodded and said, "If you come to visit our zoo, you have been to the plateau animal exhibition area, or you like animals like Tibetan fox and hozen, you can see that their favorite food is pika! Like the little mouse, but without a tail.

The pika is like the rice on the plateau, and everyone bullies it.

The fate of pikas is similar to that of prairie dogs. People think that pikas have contributed to the desertification of grasslands, and large-scale poisoning and killing has led to many raptors such as the common buzzard and the giant buzzard eating poisonous pika corpses and dying.

Through long-term monitoring, it has been found that the pasture without pika has not only not improved, but has become worse. Because pika burrows can increase the water permeability and air permeability of the soil, where there is no pika, water will not seep down, but will lead to soil erosion.

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

Wang Yan concluded: "Every large-scale killing of these cornerstone species is often a failure, and will lead to the opposite consequences. People have changed the ecosystem in a whimsical way, and then they need to pay more than they do not know. power, and turn it back into its original form.

There is only one situation that needs to be killed, and that is invasive species. "

Fang Ye added: "In a natural ecosystem, every creature has its own meaning."

The host said: "Hey, saying this, I think of wild boars! 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. Reading the news gives the impression that wild boars are already very rampant, and they are a kind of vermin. They spoil crops and may hurt people. We need to eliminate them.

In fact, wild boars play a very important role in forests. They like to arch the ground to find food. During this process, the litter, air, and soil are mixed together, and the rate of decomposition into humus becomes faster, and the seeds can germinate better, which is helpful for the succession of the forest.

When it snows in winter, it can also shave the snow away, allowing birds and small mammals such as squirrels to forage. "

The new crown is mentioned, mainly to write about animal-related changes.
