IELTS Writing Task 2 question

The most important aim of science should be to improve people’s lives. To what extent do you agree or disagree with this statement? Give reasons for your answers and include any relevant examples from your own knowledge or experience.

 

Student answer (Band 7.5)

It is often argued that improving people's lives should be the primary objective of scientific advancement. I completely agree with this view because scientific research can protect people from dangerous working conditions and contribute to major improvements in health and everyday life.

One of the most important ways in which science can improve people's lives is by reducing human involvement in hazardous activities. Certain occupations, such as mining, deep-sea exploration and the construction of high-rise structures, expose workers to considerable risks. Advances in robotics and artificial intelligence can enable machines to perform many of these tasks, thereby reducing the likelihood of serious injuries and deaths. For example, robots can be used to explore dangerous mining sites before workers enter them, allowing potential hazards to be identified without putting human lives at risk. Therefore, scientific progress can make workplaces considerably safer while also increasing efficiency.

Another major contribution of science is its ability to improve people's health and quality of life. Medical research has led to the development of vaccines, diagnostic technologies and treatments that have increased life expectancy and reduced the impact of numerous diseases. In addition, scientific advances have produced technologies that make everyday activities more convenient. Smartphones, the internet and digital communication, for instance, allow people to access information and communicate with others almost instantly, regardless of geographical distance. These developments have transformed how people work, study and maintain relationships.

Admittedly, scientific discoveries can sometimes have negative consequences if they are misused. Artificial intelligence, for example, may create privacy concerns, while technological devices can contribute to excessive screen time and electronic waste. However, these risks do not undermine the fundamental value of science. Instead, they demonstrate the need for appropriate regulation and responsible use of scientific discoveries.

In conclusion, I strongly agree that improving people's lives should be the most important aim of science. Whether by protecting people from dangerous work, advancing healthcare or making everyday activities more convenient, scientific progress has the greatest value when it contributes to human well-being.
