Many people are optimistic about the 21st century and expect scientists to make positive changes to the world. To what extent do you agree or disagree with their optimism? What changes do you like to see in your new century?

Although

being an optimist is beneficial for the well-being of every individual, it is

also

very important to be realistic. In the case of predictions for the 21st century, not expecting too many changes in the world from

scientists

may make me seem like a pessimist, but I consider it

realistic.

To begin

with, if we simply look at the past inventions that

scientists

made, the way they affected our day-to-day life is far worse than expected. Even tho,

this

probably was not their intention, they could have predicted it. A clear example of

this

is social media. I considered that the disadvantages

the advantages. If we look at the effect that they are having on the population, especially the younger population, it is clear to see that social networking has a rather bad effect on them.

Secondly

, I consider that

scientists

are not trying to solve the problem overall, but more so to make it seem like they are. An example of

this

is the invention of air cleaners.

Although

this

does resolve the problem that an individual is having it does not resolve the problem altogether,

furthermore

it makes it even worse. A change that I would really like to see is

scientists

focusing more on environmental issues like

this

one.

On the other hand

, it is widely known that

scientists

are capable of making really good changes. By

this

I mean we have seen them make amazing inventions

such

as recycling.

This

has helped our environmental issues a lot. To conclude, even tho

scientists

have not been focusing their knowledge on the right things it's never late to have a change of direction and make positive changes in the world. For

is still have hope.
