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 7.5)

It is undeniable that a considerable number of individuals assert that the current extinction of specific species of flora and fauna is the predominant environmental issue of our era. Conversely, some argue that there are more pressing ecological dilemmas that warrant attention. Although both perspectives are valid to a degree, I tend to align more closely with the latter viewpoint, and this essay will elucidate my position.

The Food and Agriculture Organization of the United Nations indicates that the economic significance of pollinators in relation to global agriculture surpasses $235 billion annually. It is estimated that approximately 35 percent of the world's food crops rely on animal pollinators for successful reproduction, implying that one out of every three bites of food we consume is contingent upon these organisms. Consequently, substantial alterations in the populations of certain species can have far-reaching ramifications on the ecosystem. For instance, the sea star preys on mussels and sea urchins, which lack natural predators. Should sea stars become extinct, the populations of mussels and sea urchins could proliferate uncontrollably, ultimately leading to significant degradation of coral reefs, demonstrating the intricate balance within ecosystems.

Nevertheless, despite concerted efforts to conserve and propagate endangered species, their populations in the wild continue to decline alarmingly. This brings to light the pressing issue of pollution as a more critical problem that necessitates urgent attention. For example, acid rain, a byproduct of air pollution, significantly alters the chemical composition of soil and water, jeopardizing ecological balance. The lowering of pH levels in marine environments adversely impacts food sources for various organisms, potentially resulting in the extinction of multiple marine species. In terrestrial ecosystems, the compromised pH level of soil hinders vegetation's ability to absorb essential water and nutrients, rendering plants weaker and vulnerable to mortality.

In conclusion, while some maintain that the extinction of specific plant and animal species is the foremost environmental challenge of our times, I strongly advocate for the recognition of other urgent issues, particularly various forms of pollution, which pose significant threats to our ecological systems.

Task Achievement / Task Response — Band 7.5

The response addresses all parts of the prompt, discussing both the importance of biodiversity and the argument for other environmental issues like pollution. Your position is clear from the introduction and maintained throughout the essay. The ideas are well-developed, particularly the example of sea stars and the impact of acid rain on soil and marine pH levels. To reach a higher band, ensure that the 'own opinion' is more explicitly linked to the comparison between the two views, rather than just presenting them as separate arguments. Overall, the task is fully addressed with relevant, well-supported arguments.

Coherence and Cohesion — Band 7.5

The paragraphing is appropriate, with a clear introduction, two body paragraphs, and a conclusion. The structure is coherent and easy to follow throughout the response.

Lexical Resource — Band 7.5

You demonstrate a wide and sophisticated range of vocabulary, such as 'predominant', 'ramifications', 'proliferate', and 'jeopardizing'. The use of topic-specific terminology like 'pollinators', 'ecological balance', and 'terrestrial ecosystems' is precise and natural. There are no noticeable errors in word choice or collocation. You successfully use less common lexical items to convey complex ideas with precision, which is characteristic of a high-level response. The vocabulary is varied and contributes significantly to the overall clarity and academic tone of the essay.

Grammatical Range and Accuracy — Band 7.5

The essay displays a wide range of complex grammatical structures, including conditional sentences ('Should sea stars become extinct...'), relative clauses, and participial phrases. The majority of sentences are error-free, and the control over punctuation and syntax is excellent. There are no significant grammatical errors that impede communication. The use of varied sentence lengths and structures keeps the writing engaging and demonstrates a high level of grammatical flexibility.
