The host nodded and said, "eating game will harm others and yourself!"

    After looking for the note again, a question came out: "someone here asked why there are fewer and fewer bats and can''t see them now?"

    Just now, I heard a few people talking about their impression of bats. Many viewers recall their childhood!

    Suddenly surprised to find that when Mingming was a child, bats felt a lot. How could they disappear unconsciously?

    Wang Yan said: "the reason is very complicated!"

    After thinking about it, he organized a language: "first, the habitat is destroyed, the area is reduced and broken, which is also a problem faced by all wild animals.

    In fact, bats are one of the most adaptable mammals to the environment, so they used to feel very common, but now humans have too much impact on the natural environment, and many environments become unsuitable for them to survive.

    The most common habitats for bats are caves, abandoned mines and tree caves, as well as some abandoned buildings. Now, the tourism development of many caves has greatly reduced the distribution range of bats, which is a very main reason. Some bats live in abandoned mines. The abandoned mines are closed or backfilled, the ruins are demolished by urban construction, the forest is cut down, and the forest land is cleared If the dead trees used to inhabit are cut down, a large number of bats will die.

    Bats are social animals. If the habitat area becomes smaller or fragmented, they can not maintain the long-term survival of the population. Casually, their habitat will be isolated from the hibernation area, unable to hibernate normally, resulting in the decline of the population.

    There are also some misconceptions about bats that make people destroy them in large numbers.

    For example, in South America, in order to prevent rabies, people have tried to kill vampire bats with poison, and even use explosives to destroy the caves where bats inhabit. They have killed not only vampire bats, but also other species of bats that share habitats with them.

    Use pesticides to kill them during hibernation, or drive them away during hibernation. Waking hibernating bats will cause them to run out of fat prematurely and die of hunger before spring.

    Durable insecticides are also a major threat. The accumulated toxins in bats will affect the development of the nervous system of young bats. The large-scale death of young bats will have a serious impact on the population, which may not recover for more than ten years.

    The other is the micro change of habitat climate. The change of habitat temperature is very important for bats, especially female bats and young bats in the late lactation stage. For example, in the summer of 1974, the cold weather prolonged the growth period of a group of bats in Indiana by two weeks and delayed the completion of migration by three weeks, affecting the fat reserve in winter, resulting in a large number of deaths Death.

    Moreover, the habitat microenvironment determines the abundance of insects. When the microenvironment is not suitable for insect growth, bats will die because of lack of food.

    Now global warming and an abnormal increase in climate will actually bring all kinds of effects we can''t see. "

    The audience listened carefully to Wang Yan''s explanation and felt worthy of being a researcher of Xinghe University. They were really knowledgeable and had all kinds of case data at their fingertips.

    It also burst out all kinds of thoughts and talked with family and friends.

    "Can''t you imagine that global warming has an impact on bats?"

    "The weather is really wrong now. It began to cool down around October in previous years. It was only in the middle of November this year that the weather cooled down."

    "Isn''t warming good for bats?"

    "We''re getting warmer, and other places may be colder! Haven''t you heard that the climate will also affect the growth of insects. Nature is so complex and precise that it plays a role in each other, and the changes in it are certainly not clear in a word."

    "The ecological role of bats is so important. Now that the habitat is destroyed, will it have any bad impact on the environment?"

    "Doesn''t seem to feel much?"

    “

    "Suddenly feel so dangerous... Is it a warning from nature?"

    "We should seriously reflect on the damage to blue stars over the years! Protect their habitat and stop damaging the natural environment!"

    I''m afraid those who say this don''t know. It''s just a beginning on earth, and the days ahead are still long.

    The host asked, "Why are bats not afraid of viruses?"

    Wang Yan said: "bats are amazing animals. During flight, their metabolic level will increase 15-16 times. Like an engine, high-frequency exercise will bring more heat, and their body temperature will be as high as 40 degrees.

    Generally, viruses infecting mammals like the environment of 367 degrees. Therefore, when people are infected with viruses, fever is a process of immune self-healing. In bats, it is difficult for ordinary viruses to survive at 40 degrees.

    The virus that can survive is also a cruel role. Such a high metabolism will also damage DNA, so it has evolved a powerful DNA repair function. "

    Fang ye said with a smile, "so the bat actually contains many valuable secrets. If we humans can deeply understand it, we may find the key to resist the virus."

    Wang Yan nodded: "it is indeed of great research value in medicine. It is not just viruses. The anticoagulant protein extracted from the saliva of blood sucking bats dissolves thrombus twice as fast as some clinical drugs."

    They answered all kinds of questions from the audience!

    I can feel that everyone''s attitude towards environmental protection and wildlife protection has indeed changed a lot, and the questions are very positive.

    I used to shout slogans. I really didn''t think it had any impact on my life. Whether you protect or poach, I don''t deal with wild animals in the city. What does it have to do with me.

    Attitude change, willing to understand the content of learning, and consciousness is also a part of "rubbing".

    At this time, if you see someone selling game in the market, you will definitely call the police without saying a word.

    At the end of the program, the host concluded: "bats are really ugly and carry viruses, but they play a very important role in the ecosystem and contribute to the maintenance of ecological balance. I hope you will have less fear of bats and understand them correctly and objectively.

    For bats and other wild animals, the correct way is to keep a distance. Respecting nature is to protect ourselves. "
