IELTS Reading Practice: Urbanization and the Loss of Natural Habitats

As an experienced IELTS instructor, I’ve noticed that questions related to urbanization and its impact on natural habitats frequently appear in the Reading section. This topic’s relevance to current global issues makes it a popular choice for test developers. Based on past trends and the ongoing significance of environmental concerns, it’s highly likely that you’ll encounter similar themes in future IELTS exams. Let’s dive into a practice exercise to help you prepare for this type of question.

IELTS Reading Passage: The Urban Sprawl and Habitat Loss

Reading Passage

The rapid expansion of urban areas, known as urban sprawl, is a global phenomenon that has far-reaching consequences for both human societies and natural ecosystems. As cities grow to accommodate increasing populations, they often encroach upon surrounding natural habitats, leading to significant environmental changes and biodiversity loss.

Urban sprawl typically involves the conversion of natural or agricultural land into residential, commercial, or industrial areas. This process not only reduces the total area of natural habitats but also fragments the remaining patches, isolating plant and animal populations. The fragmentation of habitats can disrupt ecosystems’ functioning, impeding the movement of species and reducing genetic diversity within populations.

The loss of natural habitats due to urbanization affects a wide range of species. Large mammals, such as deer or wolves, may lose their hunting or grazing grounds, forcing them to either adapt to urban environments or face population declines. Birds lose nesting sites and food sources, while amphibians and reptiles may see their breeding grounds destroyed or polluted. Even insects, which play crucial roles in pollination and decomposition, face challenges in urban environments.

Urbanization also leads to changes in local climates, known as the urban heat island effect. Cities tend to be warmer than surrounding rural areas due to the abundance of heat-absorbing surfaces like concrete and asphalt. This temperature increase can alter the behavior and life cycles of urban wildlife, potentially leading to mismatches between species and their food sources or breeding times.

Water systems are significantly impacted by urban development. Natural water bodies are often channelized or covered, while the increase in impermeable surfaces leads to greater surface runoff and reduced groundwater recharge. This can result in more frequent flooding events and degradation of aquatic habitats, affecting fish populations and other water-dependent species.

However, it’s important to note that urbanization doesn’t always spell doom for biodiversity. Some species adapt well to urban environments, taking advantage of new food sources and nesting sites. Urban parks and green spaces can provide important refuges for wildlife within cities. Moreover, many cities are now implementing “green infrastructure” projects, such as green roofs, urban forests, and wildlife corridors, to mitigate the negative impacts of urbanization on biodiversity.

Balancing urban development with habitat conservation is a complex challenge that requires careful planning and management. Sustainable urban planning strategies, such as compact city designs, can help reduce the footprint of urban areas. Conservation of key habitats within and around cities, restoration of degraded areas, and creation of green spaces can all contribute to maintaining biodiversity in urbanizing landscapes.

In conclusion, while urbanization poses significant challenges to natural habitats and biodiversity, it also presents opportunities for innovative conservation approaches. As our understanding of urban ecology grows, so too does our capacity to create cities that not only accommodate human needs but also support thriving ecosystems.

6-10. Complete the sentences below.
Choose NO MORE THAN TWO WORDS from the passage for each answer.

6. Large mammals may lose their __ or grazing grounds due to urbanization.

7. The abundance of heat-absorbing surfaces like concrete and asphalt contributes to the __ effect in cities.

8. Natural water bodies in urban areas are often __ or covered.

9. Some cities are implementing __ projects to mitigate the negative impacts of urbanization on biodiversity.

10. As our understanding of __ grows, we become better equipped to create cities that support thriving ecosystems.

Answer Key

1. B
2. C
3. C
4. C
5. B
6. hunting
7. urban heat island
8. channelized
9. green infrastructure
10. urban ecology

Explanations

1. B is correct because the passage states, “Urban sprawl typically involves the conversion of natural or agricultural land into residential, commercial, or industrial areas.”

2. C is correct. The passage mentions that habitat fragmentation “isolates plant and animal populations.”

3. C is correct. The text states that the urban heat island effect “can alter the behavior and life cycles of urban wildlife.”

4. C is correct because improved water quality is not mentioned as an impact of urbanization on water systems. The passage only mentions negative impacts.

5. B is correct. The passage states, “Sustainable urban planning strategies, such as compact city designs, can help reduce the footprint of urban areas.”

6. “Hunting” is correct. The passage mentions that large mammals may lose their “hunting or grazing grounds.”

7. “Urban heat island” is the correct term used in the passage to describe this effect.

8. “Channelized” is correct. The passage states, “Natural water bodies are often channelized or covered.”

9. “Green infrastructure” is the term used in the passage for these types of projects.

10. “Urban ecology” is the correct term. The passage concludes with, “As our understanding of urban ecology grows…”

Common Mistakes to Avoid

1. Overlooking specific details: Many test-takers struggle with questions that require precise information from the text. Always read carefully and pay attention to details.

2. Falling for distractors: In multiple-choice questions, incorrect options often contain information from the text but used in a different context. Make sure your chosen answer matches the question exactly.

3. Misinterpreting cause and effect: Be careful to distinguish between causes and effects, especially in questions about environmental impacts.

4. Generalizing too broadly: While the passage may discuss general trends, some questions might ask about specific exceptions or nuances.

5. Inserting personal knowledge: Stick to the information provided in the passage, even if you have additional knowledge about the topic.

Key Vocabulary

1. Urban sprawl (noun) /ˈɜːrbən sprɔːl/ – the uncontrolled expansion of urban areas
2. Encroach (verb) /ɪnˈkrəʊtʃ/ – to gradually take away someone’s rights, land, etc.
3. Biodiversity (noun) /ˌbaɪəʊdaɪˈvɜːsəti/ – the variety of plant and animal life in a particular habitat
4. Fragmentation (noun) /ˌfræɡmənˈteɪʃn/ – the process of breaking something into small, isolated parts
5. Ecosystem (noun) /ˈiːkəʊsɪstəm/ – all the living things in an area and the way they affect each other and the environment

Grammar Focus

Pay attention to the use of passive voice in scientific writing, as seen in this sentence from the passage:

“Natural water bodies are often channelized or covered, while the increase in impermeable surfaces leads to greater surface runoff and reduced groundwater recharge.”

Structure: Subject + be + past participle

This structure is common in academic and scientific texts to focus on the action rather than the actor. Practice identifying and using passive voice in your own writing to improve your academic English skills.
