On a hot summer night, when you are drowsy, but suddenly there is an annoying buzzing sound in your ears, like a horn of death echoing in your ears, do you feel shuddering? That's right, it's it, it's it - the mosquito, with its infamous "vampire" moniker, coming to your nightmare again

Our aversion to mosquitoes seems to be engraved in our genes, and the unbearable itching after being bitten and the deadly threat of spreading diseases have made humans hate this creature to the core. Many people may rejoice, imagining a utopia without mosquito nets, mosquito repellent water, malaria and dengue fever

Is it really that simple?

The 100-million-year-old family, a "living fossil" from the age of dinosaurs

Let's turn back 170 million years to the wild world of the Jurassic, when dinosaurs ruled the earth, and the ancestors of mosquitoes, a dipteran insect similar to flies, had begun to search for food in the feces of giant beasts, and they may have drunk the blood of dinosaurs to witness that magnificent prehistoric era

Over time, the mosquito family grew, evolving branches with different forms and habits, some of which sucked nectar and pollinated plants. Some prey on other insects to maintain ecological balance; There are also some that have evolved a formidable ability to suck blood

Yes, you heard it right, not all mosquitoes are bloodthirsty, in fact, less than 200 of the more than 3,600 species of mosquitoes in the world feed on animal blood, and the blood-sucking are all female mosquitoes, male mosquitoes usually only feed on plant sap, these "vegetarians" play a vital role in the ecosystem, they are important pollinators for many plants, maintaining the balance of the ecosystem

You might say that even if mosquitoes can pollinate, shouldn't they be eradicated because they spread diseases and harm human health?

It is true that mosquitoes are vectors of many deadly diseases, such as malaria, dengue fever, yellow fever, etc., and according to the World Health Organization, about 700,000 people die from mosquito-borne diseases worldwide every year, most of which occur in developing countries such as Africa

If we look at this issue from a higher dimension and from the perspective of the entire ecosystem, we will find that the existence of mosquitoes is not meaningless
In nature, mosquitoes are an important food source for many animals, from pitcher plants in the plant kingdom, to dragonflies in the insect kingdom, to birds, reptiles, amphibians, and even mammals, there are members who feed on mosquitoes, just imagine that if mosquitoes become extinct, these animals will lose an important food source, and the entire food chain will be affected, which may eventually trigger an unpredictable ecological disaster
How should human beings choose the wrestling between technology and ethics?
"Eradication of mosquitoes", this seemingly simple goal, is full of challenges in the face of reality
Human beings have not tried, from traditional mosquito nets, insecticides, to genetic modification, biological control, human beings in order to fight mosquitoes, can be described as painstaking, mosquitoes are like a small strong that can not be killed, can always find a gap in survival under the encirclement of human beings, they evolve at an amazing rate, can quickly develop resistance to various pesticides, and even can change blood-sucking habits, to avoid human capture
More importantly, do we really have the right to wipe a species off the face of the earth entirely? Even though this species has brought us suffering and disaster, they have survived on Earth for hundreds of millions of years and are an integral part of the ecosystem
In the face of mosquitoes, what we need is not to exterminate them, but to find a balance, a way to get along that can protect human health and maintain ecological balance
Reverence for life and harmonious coexistence with nature
Mosquitoes, these seemingly insignificant creatures, contain the mysteries of life, they are an indispensable part of the ecosystem, and they are witnesses to the long evolutionary history of nature
We should learn to respect every species, including those that cause us problems, and instead of thinking about how to eradicate them, we should try to understand them and find ways to live in harmony with them
Perhaps, one day in the future, we can use technology to control the ability of mosquitoes to transmit diseases, while retaining their role in the ecosystem, and then we can truly say that we have defeated mosquitoes, not by eradicating them, but by understanding them and living peacefully with them
