IELTS Writing Task 2 question

Some people say that the main environmental problem of our time is the loss of particular species of plants and animals. Others say that there are more important environmental problems. Discuss both these views and give your own opinion.

Give reasons for your answer and include any relevant examples from your own knowledge or experience.

Student answer (Band 8.5)

The accelerating disappearance of species and broader ecological crises both represent critical challenges, yet their interconnected nature complicates simplistic comparisons. Proponents of species conservation rightly emphasize that each extinction triggers unpredictable chain reactions. The near-disappearance of bees in parts of Europe demonstrated how pollinator loss could threaten food security, given that 75% of crops require animal pollination. Similarly, coral reef collapses in the Caribbean have not only erased marine habitats but destabilized coastal economies reliant on fishing and tourism. These cases prove that preserving biodiversity isn't merely sentimental but pragmatically safeguards human systems.

However, prioritizing climate change as the paramount issue appears equally justified given its omnipresent impacts. Melting permafrost in Siberia releasing methane, intensified hurricanes in the Gulf of Mexico, and prolonged droughts turning Mediterranean farmlands barren all illustrate how climate disruption transcends ecological niches to affect entire civilizations. Unlike localized species loss, atmospheric changes create global domino effects - a single coal plant's emissions might simultaneously bleach Australian reefs and flood Bangladeshi deltas.

Rather than competing for priority, these crises demand integrated solutions. Rewilding projects in Costa Rica show how restoring forests can both protect endemic species and sequester carbon. Kenya's adoption of solar-powered water pumps reduces fossil fuel dependence while preventing habitat destruction from energy infrastructure. This synergy suggests that framing environmental issues as either/or choices creates false dichotomies. Effective policies must address biodiversity collapse and climate change as facets of the same problem: humanity's unsustainable resource consumption. Only through systemic changes in energy, agriculture, and urban planning can we mitigate both crises simultaneously.

Task Achievement / Task Response — Band 8.5

The response fully addresses all parts of the task. You have provided a balanced discussion of both viewpoints—the importance of species conservation and the urgency of climate change—while maintaining a clear, consistent position that these issues are interconnected. The ideas are well-developed with specific, relevant examples such as the decline of bees in Europe and the impact of melting permafrost in Siberia. The argument is logical and persuasive, demonstrating a sophisticated understanding of the prompt. The conclusion effectively synthesizes the two perspectives, moving beyond a simple comparison to offer a more nuanced, integrated solution. This is a high-level response that meets all requirements of the task.

Coherence and Cohesion — Band 8.5

There is no evidence of mechanical or repetitive usage; the flow of information is natural and sophisticated throughout the entire piece.

Lexical Resource — Band 8.5

You demonstrate a wide and sophisticated range of vocabulary, using precise terminology such as 'ecological crises', 'pollinator loss', 'paramount issue', 'transcends ecological niches', and 'false dichotomies'. The collocations are natural and accurate, showing a high level of control over academic language. There are no noticeable errors in word choice or spelling. The vocabulary is not only varied but also highly appropriate for the context of an academic essay, allowing you to express complex ideas with clarity and precision.
