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?

For the time being, alterations made by

scientists

of the 21st century have never failed to provoke controversial debates among people. Some claim that we should be positive regarding the favourable modifications in science to the planet. I would contend that their optimistic statements are completely reasonable and some possible variations have kindled my interest. Obviously, the 21st century has positively marked a significant milestone in aspects related to science, especially healthcare because of the innovative medicines. Specifically, the COVID-19 pandemic has widely spread all over the world, challenging authorities to take prompt measures in order to control the breakdown of the casualties.

However

, an eclectic mix of chemists as well as governments has made a joint effort in order to perform a steady stream of scientific research with a view to coming up with a cure-all remedy to

this

serious problem.

For instance

, by allocating a colossal cost in inventing a wealth of different vaccines

such

as Pfizer or AstraZeneca for the law-abiding citizens to utilize, a high death toll resulting from the Covid-19 pandemic has deteriorated.

Therefore

, it is understandable for settlers to hold a cheerful perspective of alterations made by

scientists

in the upcoming decades. Despite the aforementioned developments in science, there is a wide range of pressing issues regarding the environment that ought to be resolved utterly to reverse the damage done to the planet.

Although

researchers from internationally acclaimed medical companies have conducted plenty of scientific research in developing waste treatment systems, they

also

need to create environmentally-friendly technology so as to alleviate environmental problems

such

as the inexorable increase in global temperature and the deterioration in air quality. To be specific, by using renewable energy

instead

of fossil fuels, people would significantly reduce carbon footprints, and

this

would have a positive environmental impact on our entire planet.

Consequently

, it is compulsory that

scientists

implement a variety of scientific investigations to curb environmental issues. 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, researchers should put efforts into creating green technology with a view to alleviating the severe environmental problems.
