Mosquitoes, disgusting flying insects, relentlessly suck on your blood and transmit malaria and various diseases by the way. People who are bitten are always angry about the death of mosquitoes, but in fact, even if humans have the ability to eradicate all whales, corals, chickens, ducks, cows and sheep on earth, they can not eradicate mosquitoes. But suddenly one day, the mosquitoes disappeared miraculously. What will happen to humans? Can human beings survive without mosquitoes on Earth?

　　Obviously, this is a problem that will not happen and there is no need to worry about it. Assuming that all the mosquitoes really disappear, the descendants of humans can only know in biology textbooks that there was such a blood-sucking worm in the age of their ancestors. At the same time, they also saw from the trees what had happened to the world without mosquitoes.

　　In fact, this issue has been discussed by both biologists and scientists. Some experts believe that the Arctic will be the first to be affected by the sudden disappearance of mosquitoes.

　　Why is it the Arctic? Biologists say the Arctic Circle is home to the largest number of mosquitoes, and if mosquitoes disappear, they are likely to have a significant impact on the Arctic tundra ecosystem. A variety of mosquitoes originated from this area. They laid eggs in that year. When the ice and snow melted in the next year, the eggs hatched rapidly and grew into adults in only three or four weeks. From northern Canada to Russia, there are countless mosquito armies appearing every year, which can be described as sheltering the sky from the sun. This is extremely rare, and there won't be such a large number of organisms in other parts of the world. Although these mosquitoes often cause diseases and disasters to the local people, they provide a large number of food sources for birds and mosquito-eating organisms in this area, and the existence of these organisms is conducive to forests and grasslands.

　　On the other hand, there are a large number of reindeer herds in this area. In order to avoid mosquito bites, reindeer migrate in the face wind path every year. The large migration of these reindeer inhibits the growth of weeds, feces nourish the land, and incidentally provides food sources for carnivorous organisms. This is a whole food chain, and if the mosquitoes disappear, the food chain system will also be destroyed. Therefore, biologists believe that the disappearance of mosquitoes will have a great impact on the Arctic.

　　Of course, it's not just the Arctic that's affected. There are mosquito-eating insects and birds everywhere in the world, such as spiders, geckos, frogs, bats and so on. Mosquitoes are the main food source for these organisms. French biologists conducted experiments in a region where they sprayed microbes and mosquito spray to kill mosquitoes in this area, but as a result, the footed swallow in this area rapidly decreased. If mosquitoes continue to occur, then mosquitoes eating mosquitoes in this area will be completely exterminated. Obviously, this is a terrible phenomenon.

　　In fact, the existence of mosquitoes does not only bring bad side to human beings, in fact, they also have good side. Mosquito larvae live in water. They feed on rotten leaves, organic gravel and microorganisms, which indirectly purify the water. While aquatic organisms such as frogs, turtles and fish feed on them, these organisms provide food sources for other organisms or humans. On the other hand, the transmission of pollen is not only the contribution of bees, butterflies, hummingbirds and natural wind. Mosquitoes are also pollen transmitters. Although this is not their main job (their main job is to suck blood), in fact, most mosquitoes feed on nectar after adulthood. Only some kinds of female mosquitoes can suck blood for the purpose of obtaining it. Protein required for oviposition. Without mosquitoes, pollination by other insects is obviously not enough.

　　From the above point of view, the earth lost mosquitoes, human may not die, but the ecological changes of nature will be 100% affected. This is the "butterfly effect". The extinction of a small insect seems insignificant, but perhaps the ultimate disaster is unimaginable.

　　As early as 1958, Texas launched an anti-mosquito campaign to kill mosquitoes by spraying DDT, but the result was too harmful. The local organisms were largely extinct because of the lack of mosquitoes for food. The Anti-mosquito Campaign stopped rapidly until the 1970s, when the local biological level recovered.

　　In fact, mosquitoes are far more numerous than humans, and their vitality is extremely tenacious, far more than humans. In fact, even if they are really extinct, there will be other organisms to take their place, of course, good or bad.
