Bab 711: Chapter 711: Bat to blessing
The oldest and strongest human emotion is fear, and the oldest and strongest fear is the fear of the unknown.
The same applies to wild animals!
In many cases, people's fear or even hatred for animals actually comes from the unknown. As they learn more about them, unnecessary fears will gradually disappear.
Like the two crawling halls of the zoo, many people were afraid of snakes at first. Through popular science exhibitions and keeper's explanations and publicity, people can understand that they don't provoke snakes, and they will not actively attack people. Friends value family affection.
There are project animals such as pig-nosed snakes, and you can touch them yourself.
In the process, I gradually became less afraid, and understood that snakes are an important member of the ecosystem and cannot harm them at will.
Fang Ye smiled and said, "So, although bats are ugly, don't dislike them or even hurt them because of this."
Wang Yan said: "The director Fang said very well. Many people may have this idea. Since the source of the new crown may be bats, why not eliminate them, won't that solve the problem?
In fact, bats are also very important cornerstone species. Although they usually appear at night and are very inconspicuous, they play a huge role in the ecosystem. "
The host leaned forward, showing an appearance of listening carefully: "Oh?"
Wang Yan said: "Take mosquitoes as an example. Everyone hates mosquitoes, right?"
Fang Ye echoed: "I'm especially afraid of mosquito bites! I will swell up when a mosquito bites me, and I belong to the kind of physique that attracts mosquitoes. I live in a dormitory with people, and mosquitoes bite me if they don't bite others."
The environment in the zoo is good, of course, the chance of getting bitten by mosquitoes is indispensable.
Fortunately, there is a systematic lottery, and some small props such as mosquito repellent incense have been drawn out, which are more effective than mosquito nets. The windows in the house will not fly in when the windows are open, so that he can sleep peacefully.
Wang Yan said: "Many bats feed on insects. They are very important insect controllers, including mosquitoes, flies, moths, and many agricultural pests. Studies have shown that a bat can eat one-third of itself every night. Weight of insects.
What is this concept? A 20-gram bat can eat about 2001,000 small insects in one night, and a bat can eat 1,520 mosquito-sized insects in one minute.
In a community, conservatively speaking, there are a dozen or twenty bats, and they can eat tens of thousands of insects in one night. This is only what they eat on the surface, not including the offspring of these insects.
The reproduction speed of these small insects is very fast. Mosquitoes can lay two or three hundred eggs at a time after sucking the blood. It only takes ten and a half months for the eggs to hatch to adults.
If there are no bats, insecticides or other methods can only be used to control these insects. "
The host was really surprised and said: "Is it so powerful?"
At this time, the popularity of the show is getting higher and higher!
Many viewers are sending messages to friends or calling family members to come and watch TV together.
Tang Xiaoxin was doing her homework and was called to allow her to watch TV together.
Originally, Fang Ye wanted to laugh, because she also had a special physique for attracting mosquitoes.
Seeing what Wang Yan said, his eyes widened: "A bat can kill thousands of mosquitoes in one night!"
Tang's mother was thoughtful at this time: "When I was a child, there were a lot of bats in front of my house, and it was true that I hadn't been bitten by mosquitoes."
Tang Xiaoxin wailed: "Why don't we have bats here! It would be great if there were more bats, and I would never be afraid of mosquitoes at night!"
Father Tang pondered: "Bats are indeed rare now! If it weren't for this epidemic, I wouldn't know that there are bats in the community."
Tang Xiaoxin participated in farming activities to understand the impact of chemical fertilizers and pesticides on the rice field ecosystem, and she had some guesses: "It is probably the cause of the pesticides! Frogs and dragonflies are also hard to see now. When the pesticides kill the insects , Poisoned the bat to death."
Sighed regretfully: "What a pity!"
Wang Yan said: "If there were no bats and these mosquitoes were rampant, our risk of contracting infectious diseases would have increased tenfold, dozens of times.
There are also their control of agricultural pests. According to statistics, a group of 150 large brown bats in the Midwest of the United States can eat 15w leafhoppers, 19w gill beetles, 33w bugs, and 60w leaf beetles each year. The female leaf beetle lays 110 eggs, which can prevent 33 million leaf beetle larvae from being born and save a large number of pumpkins, cucumbers and other crops. "
Fang Yedao: "We have a lot of traditional culture about bats in China. For example, the Chinese New Year stickers are marked with bats, right? There are also various utensils and bat decorations on buildings. When we celebrated birthdays for the elderly, Gifts decorated with bats and deer will be given, plus the old man's birthday is good fortune, longevity and longevity.
It is not only because of the homonyms of bats and blessings of bats, but they can really bring good luck. Where there are bats, the chance of getting diseased by mosquitoes will decrease, and the harvest of crops will increase.
Think about it, everyone. If the bat is located, all kinds of bad things will happen. Would the ancients use it to make auspicious decorations? Maybe the name of the bat will be changed to bat evil, bat ugly. "
"Wow!"
The audience in front of the TV exclaimed.
If some fears have just been dispelled, the attitude towards bats has changed drastically now.
Those who insisted on chasing away bats before, and even killed them, faintly felt regretful!
This is driving away blessings!
"Yes, bats have always been a symbol of auspiciousness. We have lived with bats for so many years, and nothing has happened."
"It's a pot for game eaters, not a pot for bats! Don't hurt bats."
"When I was young, there were bats that flew to the house to rest. I borrowed it all night and flew away."
"It is not bats that let the virus spread, but our harm to wild animals."
Wang Yan continued: "In addition to eating insects, bats are also prey targets of other carnivorous animals, such as monkeys, raccoons, raptors, and snakes. Among them, birds and snakes are the main predators and are the main predators in the food web. An indispensable part.
Bats are also important pollinators. Some bats feed on nectar and pollen.
In the long process of evolution, there are many plants whose flowers are highly specialized and even open at night to attract bats to pollinate, such as gourd trees and cacti!
The flowers that depend on bats for pollination vary in size, some of which are large and have wide stamens; others may have outwardly protruding petals, as if to provide a platform for bats, and pollen falls on them when bats approach the stamens.
There are also some fruit-eating bats. They are numerous and fly far. The seeds in the fruit cannot be digested and are spread during the flight of the bat.
For bats that live in caves, their feces accumulate at the bottom of the cave to provide food for the insects and fungi living in the cave.
Therefore, if bats are to be slaughtered on a large scale, the ecosystem will be hit hard. "
