Climate change and its impact on global migration patterns is a highly relevant topic in IELTS Writing Task 2. Based on recent trends, this subject has appeared frequently in past exams and is likely to continue being a popular choice for future tests. Let’s examine a typical question on this theme and provide sample essays for different band scores.

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.

Analyzing the Question

This question addresses environmental issues, specifically focusing on biodiversity loss versus other environmental concerns. It requires candidates to:

1. Discuss the view that loss of species is the main environmental problem
2. Explore other environmental issues that may be considered more important
3. Provide a personal opinion on which view is more valid

Sample Essays

Band 8-9 Essay

Climate change and its cascading effects on global ecosystems have emerged as the most pressing environmental challenges of our time. While some argue that the loss of specific plant and animal species is the primary concern, I believe that there are more critical environmental issues at stake, particularly the broader impact of climate change on global migration patterns and human societies.

Those who prioritize biodiversity loss as the main environmental problem have valid concerns. The extinction of certain species can disrupt entire ecosystems, leading to unforeseen consequences for both nature and human activities. For instance, the decline of bee populations threatens not only the survival of various plant species but also our food security, as bees play a crucial role in pollination. Moreover, the loss of biodiversity reduces our potential for medical discoveries, as many pharmaceutical compounds are derived from plants and animals.

However, I would argue that there are more urgent environmental issues that demand our immediate attention. Climate change, in particular, poses an existential threat to both human civilization and countless species across the globe. Rising temperatures, extreme weather events, and sea-level rise are already forcing people to migrate from vulnerable areas, creating a new class of “climate refugees.” This mass movement of people not only disrupts local economies and social structures but also puts immense pressure on receiving countries’ resources and infrastructure.

Furthermore, climate change exacerbates other environmental problems, including biodiversity loss itself. As habitats shift or disappear due to changing temperatures and weather patterns, many species struggle to adapt, leading to widespread extinction events. Additionally, climate change affects global water cycles, potentially causing severe droughts in some regions while increasing flood risks in others. These changes have far-reaching implications for agriculture, human health, and geopolitical stability.

In conclusion, while the loss of particular species is undoubtedly a serious environmental concern, I believe that climate change and its wide-ranging impacts on global migration patterns and human societies represent a more urgent and comprehensive threat. Addressing climate change effectively would not only help mitigate biodiversity loss but also alleviate numerous other environmental and social challenges we face today.

Climate change impact on global migration patterns

Band 6-7 Essay

Environmental problems are a big concern in today’s world. Some people think that the main issue is the loss of certain plants and animals, while others believe there are more important problems. In my opinion, both views have merit, but I think there are more pressing environmental issues to address.

Those who focus on the loss of species have good reasons. When plants and animals disappear, it can upset the balance of nature. For example, if bees die out, many plants won’t get pollinated, which could affect our food supply. Also, some animals and plants might have ingredients that could be used for medicine, so losing them means we might miss out on important discoveries.

However, I believe there are bigger environmental problems we need to worry about. Climate change is probably the biggest issue because it affects everything on Earth. It’s causing extreme weather, like more hurricanes and droughts, which make it hard for people to live in some places. This is forcing many people to move to other countries, which can cause social and economic problems.

Climate change is also making it harder for many plants and animals to survive, so it’s actually causing the loss of species too. It’s changing where food can be grown, which could lead to food shortages in some parts of the world. Rising sea levels are threatening coastal cities and islands, putting millions of people at risk of losing their homes.

In conclusion, while losing certain species is a serious problem, I think climate change is a bigger and more urgent issue. If we can solve climate change, it will help with many other environmental problems, including protecting endangered species.

Band 5-6 Essay

Environmental problems are very important today. Some people think the main problem is losing certain plants and animals. Other people think there are bigger problems. I think both ideas are important, but there are more serious environmental issues.

Losing plants and animals is bad because it can change nature. For example, if we lose bees, many plants won’t grow because bees help plants make seeds. Also, some animals and plants might have things in them that can make new medicine. If they disappear, we can’t use them anymore.

But I think there are bigger problems. Climate change is a very big problem because it changes everything. It makes the weather very bad, like more storms and less rain in some places. This makes it hard for people to live in some areas, so they have to move to other countries. This can cause problems in those countries.

Climate change also makes it hard for many plants and animals to live, so it also causes species loss. It changes where we can grow food, which can make some people not have enough food. The sea is also getting higher, which is bad for cities near the ocean.

To finish, I think losing certain plants and animals is a problem, but climate change is a bigger problem. If we fix climate change, it will help fix many other environmental problems too.
