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?

Currently, alterations in the 21st

century

that were made by

scientists

have never failed to provoke debates among

people

. It is claimed that citizens should be positive regarding the favourable modifications in

science

to the planet. I consider myself as an advocate of

this

statement and an effective modification in environmental issues would be my expectation in the new

century

. Apparently, in the 21st

century

, there is a wealth of remarkable milestones in

science

inventions that bring positive

effects

in inhabitants’ life, especially in healthcare systems . Currently, the global rampant COVID-19 pandemic has caused a high death toll to a myriad of

people

, which is

such

an alarming problem for the government all around the world.

However

, thanks to the well-developed

science

technologies and enthusiastic

scientists

, a steady stream of methods have been successfully invented with a view to helping the world have the ability to ride out from the storm.

For example

, the vaccine Pfizer and AstraZeneca, which are great results of

science

experiments, play

such

a significant role in the decrease of COVID’s negative impacts on

people

’s health. Due to these merits, it is understandable for citizens to hold a cheerful perspective of alterations made by

scientists

in the upcoming decades.

On the other hand

, there is a wide range of pressing issues related to environmental pollution that need to be handled to bring more green to the Earth, which is the modification that I want to see in the 21st

century

. Currently,

this

generation is considered a throw-away society since everyone tends to discard things despite their durability and usability, which leads to overloaded landfills. To alleviate

this

problem,

people

need to change their lifestyles.

For example

, they can switch to using reusable containers.

Hence

, it is necessary for

people

to do things that bring a harmless impact on the environment. In conclusion, even though it is reasonable for dwellers to believe in advantageous modifications made by

scientists

in the healthcare system of the 21st

century

, they should pay more attention to
