Writing Task 2 Topic: The role of urban green spaces in improving air quality.

Question: Some people argue that urban green spaces play a significant role in improving air quality in cities, while others believe that they have little or no impact on air quality. Discuss both sides of the argument and give your own opinion.

Model Answer:

Urban green spaces, such as parks, forests, and gardens, are an essential component of modern cities. While some people argue that urban green spaces play a significant role in improving air quality, others believe that they have little or no impact on air quality. In this essay, I will discuss both sides of the argument and provide my own opinion on the matter.

On one hand, proponents of the positive impact of urban green spaces on air quality argue that these areas help to filter pollutants and absorb carbon dioxide. Trees and other vegetation in green spaces can remove pollutants such as nitrogen oxides, sulfur dioxide, and particulate matter from the air through a process called phytoremediation. In addition, plants absorb carbon dioxide, a major greenhouse gas, which helps to mitigate global warming and improve overall air quality. Furthermore, urban green spaces can create microclimates that reduce heat island effects, leading to lower temperatures and less demand for air conditioning systems in cities. This reduction in energy consumption can lead to lower emissions of pollutants from power plants.

On the other hand, critics argue that urban green spaces are not the most effective means of improving air quality in cities. They contend that while green spaces may have a limited impact on localized air quality, they cannot compensate for the vast amounts of pollution produced by industrial processes and vehicular emissions. Additionally, critics point out that large-scale deforestation or urbanization efforts can actually worsen air quality by removing natural filters and creating dust bowls, which can lead to increased respiratory illnesses.

In my opinion, while it is true that urban green spaces may have a limited impact on overall air quality in cities, they are an essential part of urban planning and design. The benefits of improved air quality, such as better health outcomes and reduced energy consumption, should not be underestimated. However, to achieve meaningful improvements in air quality, a comprehensive approach is necessary that includes stricter emissions regulations, the promotion of sustainable transport options, and the preservation and expansion of urban green spaces.

Overall, while urban green spaces may have limited impact on air quality, they are still an essential component of modern cities. By combining green spaces with other strategies to reduce pollution, we can create healthier and more sustainable urban environments for all residents.

Score: Band 7.5

This response demonstrates a clear understanding of the topic, presents both sides of the argument effectively, and provides a well-reasoned opinion. The essay is coherently structured, with appropriate use of paragraphs and transitions.
