Wild animals have no use in the 21st century and trying to preserve animals now is just a waste of money. To what extent do you agree or disagree with this opinion?

Nowadays, there are a number of people who believe wild

animals

have no use in

this

modern era. The government allocates a budget to preserve

this

creature. In fact, I firmly disagree with the statement and believe that

animals

play crucial parts in the 21st century. The first reason why preserving wild

animals

beneficial is to keep the ecosystem balanced. The absence of wild

animals

will affect the food chain. Some

animals

can be overpopulation.

For instance

, the number of rats will be overpopulated because the snake as a wild animal becomes extinct. By preservation,

animals

can keep their position in the food chain.

As a result

, the food chain will stay stable and keep nature balanced. The second reason is wild

animals

can be beneficial for medical research. There are many experiments to help human lives by using these

creatures

. For illustration, scientists use Komodo dragons' saliva to cure strokes. Many people who suffer from strokes can be helped. These

creatures

also

can be useful for looking at other medicines. By allocating a budget for wild

creatures

' preservation, scientists can keep searching for many cures that are essential for humans.

Consequently

, the citizen's life expectancy will be improved.

To sum up

,

although

many people believe that wild

animals

do not contribute anything for 21th century, these

creatures

have proven beneficial for society

such

as keeping the ecosystem balanced and providing cures for some medical issues. Having considered the pros, I am strongly convinced that preserving wild

animals

is a wise decision.
