Redesigning the World's Deadliest Animal

Mosquitoes are small insects, but they are very dangerous. They kill more people than any other animal in the world. They do not kill people directly. They spread diseases like malaria, dengue, and yellow fever.

Scientists want to stop this problem. They use a tool called CRISPR to change mosquito DNA. This can help make mosquitoes unable to spread diseases.

Some scientists release special male mosquitoes. These mosquitoes cannot make babies. This helps to reduce the number of mosquitoes.

But mosquitoes are not all bad. Birds, fish, and other animals eat them. Some mosquitoes also help plants grow. So scientists must be careful. They need to protect nature too.
