Passage
When we are young, we learn that tigers and sharks are dangerous
animals. We might be scared of them because they are big and powerful. As we
get older, however, we learn that sometimes the most dangerous animals are also
the smallest animals. In fact, the animal that kills the most people every year
is one that you have probably killed yourself many times: the mosquito.
While it may seem that all mosquitoes are biters, this is not actually
the case. Male mosquitoes eat plant nectar. On the other hand, female
mosquitoes feed on animal blood. They need this blood to live and produce eggs.
When a female mosquito bites a human being, it transmits a small amount of
saliva into the blood. This saliva may or may not contain a deadly disease. The
result of the bite can be as minor as an itchy bump or as serious as death.
Because a mosquito can bite many people in the course of its life, it
can carry diseases from one person to another very easily. Two of the most
deadly diseases carried by mosquitoes are malaria and yellow fever. More than
700 million people become sick from these diseases every year. At least 2
million of these people will die from these diseases.
Many scientists are working on safer and better ways to kill mosquitoes,
but so far, there is no sure way to protect everyone in the world from their
deadly bites. Mosquito nets can be placed over beds to protect people against
being bitten. These nets help people stay safe at night, but they do not kill
any mosquitoes. Mosquitoes have many natural enemies like bats, birds,
dragonflies, and certain kinds of fish. Bringing more of these animals into
places where mosquitoes live might help to cut down the amount of mosquitoes in
that area. This is a natural solution, but it does not always work very well.
Mosquitoes can also be killed with poisons or sprays. Even though these sprays
kill mosquitoes, they may also harm other plants or animals.
Although mosquitoes may not seem as scary as larger, more powerful
animals, they are far more dangerous to human beings. But things are changing.
It is highly likely that one day scientists will find a way to keep everyone
safe from mosquitoes and the diseases they carry.
