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 8.0)

The optimal balance of priorities within environmental advocacy is a subject of intense debate, as the planet faces an array of ecological crises. While a significant body of opinion holds that the accelerating loss of unique flora and fauna species stands as the most critical ecological disaster of our time, another faction argues that systemic challenges like global climate change present far more urgent threats. In my view, while biodiversity loss is catastrophic, it is primarily a symptom of broader systemic disruptions; therefore, tackling overarching issues like atmospheric warming and global pollution constitutes a far more critical priority.

On the one hand, proponents of prioritizing biodiversity argue that the extinction of plant and animal species causes irreversible damage to global ecosystems. Nature operates through highly intricate, interdependent food webs and biological chains; the removal of even a single keystone species can trigger an ecological collapse. For instance, the ongoing decline of global bee populations severely threatens the pollination vectors required for wild flora survival and agricultural stability. Furthermore, when unique plant species go extinct, humanity permanently loses potential sources of medical breakthroughs, as many modern pharmaceuticals are synthesized from rare botanical compounds found in pristine habitats like the Amazon Rainforest. From this perspective, the rapid depletion of the planet's genetic library represents an absolute, non-negotiable emergency that demands immediate containment.

On the other hand, a compelling counterargument suggests that isolating species loss overlooks the broader, systemic issues that actively drive that very extinction. Global climate change, propelled by industrial greenhouse gas emissions, serves as an existential umbrella crisis that alters the fundamental livability of the planet. Rising global temperatures, ocean acidification, and shifting weather patterns systematically destroy natural habitats on a macro scale, making species survival impossible regardless of localized conservation efforts. For example, according to data from marine conservation organizations like the Great Barrier Reef Foundation, rising sea surface temperatures drive mass coral bleaching events, decimating entire marine ecosystems simultaneously. Therefore, focusing resources primarily on protecting individual animals without correcting the underlying atmospheric warming is akin to treating a symptom while ignoring the terminal illness.

In my opinion, while both perspectives highlight valid emergencies, systemic environmental issues must take precedence because they have a compounding, universal impact. Widespread industrial pollution, microplastic contamination, and deforested landscapes do not merely threaten a few specialized organisms; they degrade the fundamental life-support systems—clean air, fresh water, and fertile soil—upon which all living things, including humanity, depend. Resolving macro-crises like the transition to renewable energy and the enforcement of global carbon caps automatically yields a stabilizing effect on biodiversity, creating protected, stable conditions where endangered species can naturally recover.

In conclusion, both viewpoints reflect critical dimensions of modern ecological strain: one focuses on the visible loss of biological diversity, while the other addresses the structural decay of the biosphere. Although the eradication of unique flora and fauna is a profound tragedy, I believe that macro-environmental threats like climate change are more important, as their resolution is the fundamental prerequisite for safeguarding all life on Earth.

AI examiner evaluation

Task Achievement / Task Response: Band 8.5

The response fully and effectively addresses all parts of the prompt. The candidate thoroughly examines both views—the prioritization of plant and animal species loss versus broader systemic environmental threats like climate change—and provides a well-developed, clear personal opinion throughout the essay. Ideas are extended and supported with relevant, specific examples, such as the decline of global bee populations and data regarding marine coral bleaching events. The position is consistently maintained and logically argued from the introduction through to the conclusion, meeting all requirements of the task with a high level of academic sophistication and insight.

Coherence and Cohesion: Band 8.0

Ideas are logically sequenced and seamlessly progressed throughout the essay. The essay is skilfully divided into distinct, appropriate paragraphs that handle each section of the prompt cleanly.

Paragraphing is used sufficiently and appropriately, contributing to a coherent and unified overall structure.

Lexical Resource: Band 8.0

The candidate demonstrates a wide, fluent, and flexible range of vocabulary, utilizing sophisticated and uncommon lexical items with skill and precision. Expressions such as 'optimal balance of priorities,' 'intricate, interdependent food webs,' 'existential umbrella crisis,' and 'structural decay of the biosphere' reflect an advanced command of English. Word choice and collocation are generally very natural, with only occasional minor stylistic awkwardness. Spelling and word formation are entirely accurate throughout the response.

Grammatical Range and Accuracy: Band 8.0

The writing exhibits a wide and varied range of complex sentence structures, including conditional clauses, participial phrases, and elaborate relative clauses.
