Topic #5: Why Does This Exist?

            As you all know, there are many things that we cannot explain on the world. For instance, mosquitoes. I also used to wonder why mosquitoes exist on Earth when I was a child. To me, they are really useless animals because they know only suck blood of humans and another ones.
           I used to look for more information about this animal. Then, I was surprised, for they have existed on our planet around 170 million years. They appear in tropical countries, including Vietnam, and they are particularly sensitive to people who have blood group O like me. That why I am often bitten, and I feel itchy, uncomfortable and frustrating. In addition, being bitten by mosquitoes can cause high mortality, including dengue fever, etc.
           People often use lizards, fish and bats to kill mosquitoes. In other words, they exist to be food of lizards, fish and bats. As professor May, I continued to ponder on this animal' s existence a little more. Do they exist to help the increase in sale of anti-mosquito products worldwide? And I have not had the answer yet.

  1. I think if we did not have mosquitoes, other animals still can live with different food.

  3. Haha! Really? Have you noticed that other type O people get bit more often? I am type A, and if I come to think of it, I do not get bit as badly as others. I am now going to have to ask around about this!
