How many species are there on the living earth? According to a preliminary estimate by experts, the number of species on earth is no less than 30 million. So, if there's one thing we find the least useful, the least annoying, the mosquito is on the list.
When summer comes, you hear the hum and suddenly get a big red envelope in your hand, and you wonder: What's the use of mosquitoes on earth? Mosquitoes should just disappear. They have no reason to exist.
On the surface of data, there are about 2,000 kinds of mosquitoes on the earth, and more than 80 kinds of diseases can be transmitted. There are anopheles mosquitoes that can transmit malaria, culex mosquitoes that can transmit filariasis and Japanese encephalitis, and Aedes mosquitoes that can transmit Japanese encephalitis and dengue fever. Although they are small, a slap can kill, but, in the earth, in our side, perhaps no other creature is more harmful to human beings than mosquitoes.
Mosquito plan
In the face of such a repellent mosquito, people also do their best. Scientists in the United States have genetically engineered mosquitoes that do not have the ability to catch malaria and released them into the wild in an attempt to effectively cut off transmission between humans and mosquitoes. The modified mosquitoes carry a protein called SM1, which makes them more vigorous.
The results showed that the genetically modified mosquitoes lived up to expectations, adapting quickly and producing offspring that carried less malaria. That seems fine, but environmental groups are protesting, arguing that the genetically modified mosquitoes are unsafe, and that it is possible to do so based on the results of a brief experiment, and that if other uncontrollable mutations occur, the damage will be unimaginable.
After that, of imperial college, London, the team also transform another gm mosquitoes, the male gm mosquitoes with fluorescent testes, if with wild mosquitoes after mating, the resulting offspring will not have reproductive ability, it can gradually reduce the number of mosquitoes, mosquito will eventually disappear from this world.
The role of mosquito presence
But is it really a good thing that mosquitoes are gone?
On the surface, if mosquitoes disappear, mosquito-related enterprises in the world, such as mosquito repellent incense, mosquito repellent devices, will go bankrupt, which may cause the butterfly effect, resulting in a wave of unemployment and financial crisis.
There are more than 80 species of mosquitoes besides those that spread disease. Some mosquitoes live entirely on plant and fruit nectar. Like bees, they are "little gardeners" who carry pollen and don't bite us.
And while mosquitoes may be humble, obnoxious, and at the bottom of the ecosystem, they are born with a sense of purpose. From their eggs to adults, dragonflies, frogs, fish, birds and other creatures feed on them.
They're there for a reason, because if they do go extinct, then the chain of life will be disrupted, and we all know that the chain of life is interlinked, and if you lose mosquitoes, there might be something even more troublesome to replace them.
conclusion
There are many kinds of mosquitoes, some good and some bad, but most of them are good for ecology. For mosquitoes, xiaobian believes that there is no need to protect them or kill them all, as long as they are controlled in a certain number. And the earth's ecological chain is a whole, but any attempt to change, will be bitten. At the extreme, humans are no more important to the planet than mosquitoes.
