Personally, living in an area where mosquitoes are common is difficult. Children playing outside must wear horrible bug spray that still burns their eyes after many changes to the product. The repellent is also not the only issue. Itchy bites can actually cause more harm than someone thinks. According to Quaro.Com, a certain article states that, "The average human at about 150 pounds has about five liters of blood in their body. A mosquito on average will suck five millionths (0.000005) of a liter of blood. So dividing, it would take 5/0.000005 = 1,000,000 mosquitoes to drain all five liters from the human body. However, a loss of over 40% (about two liters), if untreated with a blood transfusion, will most likely result in death." Mosquitoes can also carry diseases, which may also lead to death. If scientists and doctors find a way to get rid of mosquitoes, than people in heavily populated areas wont have to live with them.
When most medical studies are done, not only do researchers look at the diseased for answers and cures, they look at the immune. Unlike the diseased, the immune are stronger than the disease itself. The same should go for developing an understanding on why Iceland has no mosquitos. Although most agree that climate is what affects the fact that mosquitos survive in some areas and not in Iceland, there are also other factors that need to be observed. This is because in areas like greenland there are still mosquitos present, despite the chilling climate. So, even though climate is likely to be one of the factors, researchers still need to dig deeper into the many possible factors in order to attain a rich understanding.
I think that understanding why Iceland does not have mosquitoes could help us eradicate them elsewhere. Mosquitoes are a primary carrier of diseases, especially in tropical areas, as well as being just a general nuisance. Understanding why they are not living in Iceland could potentially improve length and quality of life for millions of people.
It is most likely the climate that is at work in controlling the mosquito population in Iceland. Mosquitoes require a stagnant, warm, wet environment in which to breed. the fact that Iceland is so cold probably plays a huge role in the fact that there are no mosquitoes. It is still worth looking into, to see if there are other factors involved, from which we can learn.
It is always helpful to study a change in a pattern. For some reason, the climate in Iceland doesn't sustain mosquitoes. If we can put our finger on the reason, we can create this condition in other countries. This is helpful because there are a lot of people that are hurt by mosquitoes each year.
Understanding why there are no mosquitos in Iceland will likely do little to help us eradicate them in other regions of the world. Almost certainly, the answer comes down to the island country's climate, which is impossible to replicate, as it is not something that humanity controls (well, we've affected climate change, but that's another story).
Iceland does not have mosquitoes because it turns cold to fast for the mosquitoes to grow and develop. We can not do that to ever country or else it can kill of other species such as reptiles. Then that affects us and biodiversity. It is bad enough we are already killing animals we can't kill more.
