Some people believe that the increased pollution in cities is an unavoidable consequence of urbanization and economic development. To what extent do you agree or disagree with this statement?
Analyzing the Question

- Express your opinion on whether increased pollution is inevitable in urban areas
- Discuss the link between economic growth and environmental degradation
- Consider possible solutions or alternatives to this problem
Band 8-9 Sample Essay
Here’s a high-scoring sample essay that addresses the question effectively:
Urbanization and economic progress have undeniably led to increased pollution in many cities worldwide. However, I strongly disagree with the notion that this is an unavoidable consequence. While it’s true that rapid urban growth often results in environmental challenges, I believe that with proper planning and innovative solutions, cities can develop economically without sacrificing environmental quality.
Firstly, it’s important to acknowledge that urbanization does contribute to pollution. As cities expand, the demand for energy, transportation, and industrial production increases, leading to higher emissions of pollutants. For instance, the rapid growth of megacities like Beijing and Delhi has resulted in severe air quality issues, primarily due to vehicle emissions and industrial activities. However, this doesn’t mean that pollution is an inevitable outcome of urban development.
Urban pollution sources
Many cities around the world have demonstrated that economic growth and environmental protection can coexist. Singapore, for example, has achieved remarkable economic success while maintaining strict environmental standards. The city-state has implemented comprehensive urban planning, efficient public transportation systems, and green building initiatives, proving that urbanization doesn’t have to come at the cost of environmental degradation. Similarly, Copenhagen’s commitment to becoming carbon-neutral by 2025 showcases how cities can pursue ambitious economic goals while prioritizing sustainability.
Moreover, technological advancements are increasingly providing solutions to urban pollution problems. The development of cleaner energy sources, such as solar and wind power, is reducing reliance on polluting fossil fuels. Electric vehicles and improved public transportation systems are helping to curb vehicle emissions in many cities. Additionally, innovative urban planning approaches that incorporate green spaces and promote walkability are creating more livable and less polluted urban environments.
Sustainable city solutions
In conclusion, while the challenges of pollution in growing cities are significant, they are not insurmountable. With strong political will, innovative urban planning, and the adoption of green technologies, cities can achieve economic development without compromising environmental quality. The examples of successful sustainable urban development around the world prove that pollution is not an inevitable consequence of urbanization, but rather a challenge that can be effectively addressed with the right strategies and commitment.

Band 6-7 Sample Essay
Here’s a sample essay that would likely score in the Band 6-7 range:
In recent years, many cities have experienced increased pollution as they grow and develop economically. While some people think this is unavoidable, I partially disagree with this view. Although urbanization often leads to more pollution, I believe there are ways to reduce its impact.
It’s true that as cities get bigger, they usually produce more pollution. This is because more people means more cars, factories, and energy use, which all create pollution. For example, in many developing countries, big cities like Mumbai or Jakarta have serious air pollution problems because of all the traffic and industry.
However, I don’t think this means pollution has to keep getting worse as cities grow. There are things that can be done to reduce pollution even as cities develop. One way is to use cleaner energy sources like solar or wind power instead of coal or oil. Another is to improve public transportation so fewer people need to drive cars. Some cities are also making rules to limit pollution from factories and encouraging people to recycle more.
Urban planning with green spaces
Cities can also plan better to reduce pollution. For instance, they can create more parks and green spaces, which help clean the air. They can also design buildings to be more energy-efficient. These things can help cities grow without making pollution much worse.
In conclusion, while it’s true that urbanization often leads to more pollution, I don’t think this is completely unavoidable. With good planning and new technologies, cities can develop economically while also protecting the environment. It’s important for governments and people to work together to find ways to grow cities sustainably.
