To begin with, the advent of science has transformed our lives in a positive way, particularly our health. A good example of it is the development of Covid 19 vaccines. Prior to their invention, colossal numbers of people passed away on the grounds that their bodies didn't have antibodies to combat the virus. Thanks to scientific development, medical companies like Pfizer provided vaccinations for residents in 2020, which helped to boost their immune systems to fight against novel viruses. As a result, everyone can now go to the park without wearing masks or using hand sanitiser.
