叮人手的蚊子 網絡截圖
What will happen if mosquitoes disappear from the earth?
With the rise of the temperature, many mosquitoes（蚊子） come out again.Mosquitoes, such insects, can be said to be annoying.This kind of creature, which has lived for hundreds of millions of years, is difficult to be liked by human beings.Although we have taken many measures to kill mosquitoes, there are so many mosquitoes that we spend every summer in the beautiful songs of mosquitoes.If, I say, mosquitoes will disappear from the earth one day for some reason.How will humans react?
Happiness is certain, but after happiness, human beings will usher in a longer period of suffering.
In the biosphere（生物圈）, although mosquitoes feed on blood and spread diseases, they have a very bad reputation（名聲）, but there are more than 3500 species of mosquitoes in the world, and there are about a hundred species of mosquitoes harmful to human beings.In more cases, mosquitoes play the most basic role in nature, that is, like Antarctic（南極地區的） krill（磷蝦）, they become the basic food for many animals.Every summer, mosquitoes in the Arctic block out the sun, providing food for countless migratory（遷徙） birds.Once mosquitoes become extinct（滅絕的）, the number of migratory birds that feed on mosquitoes in the Arctic will be reduced by at least half.
In fact, there are many fish and insects that feed mainly on mosquitoes. Mosquito larvae grow underwater and fish are easy to get.If mosquitoes become extinct, hundreds of fish species will have to change their diet to survive, and their survival will be wiped out.
Scientists have estimated that once mosquitoes become extinct, 3500 species of mosquito-related organisms will become endangered or extinct.Of course, these animals may also be looking for alternatives to mosquitoes, but the options are very limited.
After a period of time after the extinction of mosquitoes, humans will find the negative（消極） effects caused by the disappearance of mosquitoes.
First of all, many plants in the plant kingdom（王國） will only blossom and not bear fruit, because there are obviously fewer bees than mosquitoes, and many mosquitoes live on nectar, which indirectly has the effect of pollination. Once mosquitoes become extinct, the impact on these plants is enormous.
Next, there is the extinction of animals, the speed of extinction of life on the earth is accelerating, and the extinction of mosquitoes will make more creatures unable to find the hope of survival on the earth.
Finally, mosquito incense factories, mosquito net factories and even Hualu waterworks will close down because of the disappearance of mosquitoes.People will lose a lot of jobs as a result, including ours.
In that case, will you still hope that the mosquitoes will disappear from the earth?

正在吸血的蚊子 網絡截圖
隨著氣溫的回升，不少蚊子又出來活動了。蚊子這種昆蟲，可以說人見人煩。這種生活了上億年的生物很難受到人類的喜歡。雖然我們採取了許多辦法殺傷蚊子，但蚊子的數量是那麼多，每一年夏天我們都是在蚊子的美妙歌聲中度過的。如果，我說如果，蚊子有一天的因為某種原因從地球上消失了。人類會作何反應？
開心是一定的，但在開心過後，人類將迎來更長時間的難受期。
在生物圈中，蚊子雖然吸食血液，傳播疾病，名聲非常不好，但世界上蚊子的種類超過了3500種，對人類有害的蚊子有一百種左右。蚊子在更多情況下，承擔著自然界最基礎的作用，那就是和南極磷蝦一樣，成為許多動物的基本口糧。每年夏天，北極地區的蚊子遮天蔽日，為無數候鳥提供了食物。蚊子一旦滅絕，北極地區以蚊子為主食的候鳥數量至少會減少一半。
實際上有許多魚類和昆蟲，都是以蚊子為主食的，蚊子的幼蟲在水下生長，魚類很容易獲取。如果蚊子滅絕，數百種魚類都必須改變食譜才能生存下去，它們的生存也會遭到滅頂之災。
科學家曾估計，一旦蚊子滅絕，和蚊子相關的3500種生物也就將變得瀕危或者滅絕。當然，這些動物也可能尋找除了蚊子之外的替代品，但可供選擇的非常有限。
蚊子滅絕後的一段時間，人類就會發現因為蚊子消失帶來的負面影響。
首先，植物界中的許多植物，將會只開花不結果，因為蜜蜂顯然數量不如蚊子多，許多蚊子都是靠吸食花蜜為生的，間接起到了授粉的效果，蚊子一旦滅絕，對這些植物的影響相當巨大。
接下來，就是動物滅絕，原本地球生物滅絕的速度就在加快，蚊子的滅絕將會讓更多的生物找不到在地球上生存的希望。
最後，蚊香廠，蚊帳廠，甚至花露水廠都將會因為蚊子的消失而倒閉關門。人們因此會失去很多的工作崗位，包括我們的。
這樣的話，你還會盼著蚊子從地球上消失嗎？
