Urbanization and its effects on environmental sustainability have become a recurring theme in IELTS Writing Task 2. This topic has appeared frequently in recent years and is likely to continue being a popular choice for examiners due to its global relevance. Let’s explore this subject in depth, providing you with the tools to excel in your IELTS writing task.

Analyzing the Topic

The relationship between urbanization and environmental sustainability is complex and multifaceted. It touches on various aspects such as pollution, resource consumption, biodiversity loss, and climate change. When approaching this topic in IELTS Writing Task 2, it’s crucial to consider these different angles and their interconnections.

Let’s examine a typical question you might encounter:

Some people believe that the growth of cities is destroying the natural environment. To what extent do you agree or disagree with this statement?

This question asks you to evaluate the impact of urban expansion on nature and express your opinion on the matter. Let’s break down the key elements:

1. The growth of cities (urbanization)
2. Destruction of the natural environment
3. Your level of agreement with the statement

Sample Essay (Band 8-9)

Here’s a high-scoring sample essay addressing the question:

Urbanization, the process of rural areas transforming into cities, has been a defining trend of the 21st century. While some argue that this growth inevitably leads to environmental degradation, I partially agree with this statement, as the reality is more nuanced.

Undoubtedly, rapid urban expansion often comes at the expense of natural habitats. As cities grow, forests are cleared, wetlands are drained, and green spaces are converted into concrete jungles. This destruction directly impacts local ecosystems, leading to biodiversity loss and disrupting natural processes. Moreover, the increasing population density in urban areas results in higher levels of pollution – from air pollution due to traffic and industrial activities to water pollution from inadequate waste management systems.

However, it would be overly simplistic to claim that urban growth always destroys the environment. Modern urban planning increasingly incorporates sustainable practices that can mitigate environmental damage. For instance, many cities are implementing green building standards, investing in renewable energy, and creating urban green spaces. These initiatives not only reduce the environmental footprint of cities but can also enhance biodiversity within urban areas. Cities like Singapore have demonstrated that urban development and nature conservation can coexist, with their extensive parks and nature reserves integrated into the urban landscape.

Furthermore, urbanization can indirectly benefit the environment by concentrating human activities. This concentration can lead to more efficient use of resources and energy compared to dispersed rural settlements. Urban areas often have better public transportation systems, reducing per capita carbon emissions. Additionally, the high population density of cities can preserve larger areas of natural habitat elsewhere, as less land is needed for human settlement overall.

In conclusion, while urban growth does pose significant challenges to the natural environment, it is not inherently destructive. The key lies in how this growth is managed. With thoughtful planning and a commitment to sustainability, cities can evolve in ways that minimize environmental harm and even contribute to conservation efforts. The future of our planet depends on our ability to create urban environments that coexist harmoniously with nature.

Urban growth and nature

Sample Essay (Band 6-7)

Now, let’s look at a mid-range essay addressing the same question:

Many people think that as cities get bigger, they destroy the natural environment. I mostly agree with this idea because I can see many examples of how city growth harms nature, but I also think there are some ways cities try to help the environment.

First, when cities grow, they often take over natural areas. Trees are cut down to make space for buildings and roads. This destroys the homes of many animals and plants. Also, more people in cities means more pollution. Cars and factories in cities produce a lot of air pollution, which is bad for both nature and people’s health. The concrete used in cities also creates heat islands, making cities much hotter than natural areas.

However, some cities are trying to be more environmentally friendly. They are making parks and planting trees to bring nature back into the city. Some new buildings are designed to use less energy and water. These are good steps, but they don’t fully make up for the damage done to nature when cities expand.

Another problem is that cities use a lot of resources. They need a lot of water, food, and energy, which often comes from far away. This can put pressure on natural resources in other areas. But, on the other hand, having many people live close together in cities can sometimes be more efficient than if they lived spread out in the countryside.

In conclusion, I think the growth of cities does mostly harm the natural environment. While there are some efforts to make cities greener, the overall impact of urban expansion on nature is still negative. We need to find better ways to grow our cities without destroying the natural world around us.
