Climate change and its effects on marine ecosystems have become increasingly prevalent topics in IELTS Writing Task 2. Based on recent trends and the growing global concern for environmental issues, it’s highly likely that this subject will continue to appear frequently in future exams. Let’s explore a relevant question that has appeared in past IELTS tests and craft sample essays to help you prepare effectively.
Analyzing the 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.
This question directly relates to the impact of climate change on marine ecosystems, as the loss of species is a significant consequence of environmental changes. Let’s break down the key elements:
- Two viewpoints are presented:
- The main environmental problem is the loss of specific plant and animal species.
- There are more important environmental problems.
- You need to discuss both views.
- You should provide your own opinion.
Sample Essay for Band 6-7
Here’s a sample essay that would likely score in the Band 6-7 range:
In recent years, environmental issues have become a major concern worldwide. While some people believe that the extinction of certain plant and animal species is the most critical environmental problem, others argue that there are more pressing matters to address. This essay will discuss both perspectives before presenting my own view.
On one hand, those who prioritize the loss of species have valid reasons for their concern. The disappearance of plants and animals can disrupt entire ecosystems, leading to unforeseen consequences. For example, the decline of bee populations threatens not only honey production but also the pollination of many crops essential for human food supply. Additionally, biodiversity loss may deprive us of potential medical discoveries, as many medicines are derived from plants and animals.
On the other hand, proponents of the opposing view argue that other environmental issues deserve more attention. They point to problems such as climate change, air and water pollution, and deforestation as more urgent threats to the planet’s health. These issues affect not only specific species but also human populations and the entire global ecosystem. For instance, rising sea levels due to climate change endanger coastal communities and marine habitats alike, making it a more comprehensive problem.
In my opinion, while the loss of species is undoubtedly a serious issue, it is often a symptom of larger environmental problems. I believe that addressing overarching issues like climate change and pollution will indirectly help preserve endangered species and their habitats. By focusing on these root causes, we can create a more holistic approach to environmental protection.
In conclusion, both viewpoints have merit, but I believe that tackling broader environmental challenges is more crucial. By addressing these fundamental issues, we can hope to mitigate species loss and protect the planet’s biodiversity as a whole.

Sample Essay for Band 8-9
Now, let’s look at a sample essay that would likely score in the Band 8-9 range:
The debate over which environmental issue should be considered the most critical of our time has intensified in recent years. While some argue that the loss of particular plant and animal species is the primary concern, others contend that there are more pressing environmental problems to address. This essay will examine both perspectives before offering a nuanced view on this complex issue.
Those who prioritize the loss of biodiversity argue that the extinction of species represents an irreversible tragedy with far-reaching consequences. The intricate web of life on Earth depends on the delicate balance between various species, and the loss of even a single species can trigger a cascade of ecological disruptions. For instance, the decline of keystone species like sea otters in marine ecosystems can lead to the overgrowth of sea urchins, which in turn decimates kelp forests – crucial habitats for numerous other species. Moreover, biodiversity loss threatens potential scientific breakthroughs, as many medical advancements and technological innovations draw inspiration from nature’s diverse forms and functions.
Conversely, proponents of the alternative view argue that more encompassing environmental issues demand our immediate attention. They point to climate change, pollution, and habitat destruction as problems that not only contribute to species loss but also pose existential threats to human civilization and the planet as a whole. The far-reaching impacts of climate change, such as rising sea levels, extreme weather events, and ocean acidification, affect entire ecosystems and human societies alike. Furthermore, addressing these overarching issues could indirectly mitigate biodiversity loss by preserving habitats and stabilizing environmental conditions.
In my view, it is crucial to recognize the interconnectedness of environmental challenges rather than treating them as isolated problems. While the loss of species is indeed a grave concern, it is often a symptom of broader environmental degradation. A holistic approach that targets the root causes of environmental damage – such as unsustainable resource exploitation, pollution, and greenhouse gas emissions – would be more effective in preserving biodiversity and addressing other ecological issues simultaneously.
In conclusion, while the extinction of species is a significant problem, I believe that focusing on the underlying causes of environmental degradation is more crucial. By adopting a comprehensive strategy that addresses climate change, pollution, and habitat destruction, we can hope to safeguard biodiversity while also tackling other pressing environmental challenges. This integrated approach is essential for ensuring the long-term health and resilience of our planet’s ecosystems.
