IELTS Writing Task 2: Mastering Essays on Climate Change and Global Water Resources with Sample Band 8, 7, and 6 Responses

Climate change and its impact on global water resources is a crucial topic that has gained significant attention in recent years. This subject has appeared frequently in IELTS Writing Task 2 questions and is likely to remain relevant in future exams. Based on past exam trends and the growing importance of environmental issues, we can expect to see more questions related to this theme. Let’s explore a sample question and analyze how to approach it effectively.

Some people believe that climate change is the biggest threat to the world’s water resources. To what extent do you agree or disagree with this statement?

Analyzing the Question

This question requires candidates to express their opinion on the relationship between climate change and global water resources. The key aspects to consider are:

1. The phrase “to what extent” indicates that a balanced approach is necessary.
2. Candidates should discuss how climate change affects water resources.
3. Other potential threats to water resources should be mentioned for comparison.
4. A clear stance must be taken, supported by relevant examples and explanations.

Sample Essay 1 (Band 8-9)

Climate change is undeniably a significant threat to the world’s water resources, and I largely agree that it poses the most substantial risk. However, it is crucial to acknowledge that other factors also contribute to the deterioration of global water supplies.

The impact of climate change on water resources is profound and multifaceted. Rising global temperatures lead to altered precipitation patterns, resulting in more frequent and severe droughts in some regions while causing excessive rainfall and flooding in others. This unpredictability disrupts the natural water cycle, affecting both surface and groundwater availability. Moreover, melting glaciers and polar ice caps, direct consequences of global warming, threaten freshwater sources for millions of people worldwide. The resulting sea-level rise also leads to saltwater intrusion into coastal aquifers, further compromising freshwater supplies.

Climate change impact on water resources

Nevertheless, it would be remiss to ignore other significant threats to water resources. Industrial pollution, for instance, continues to contaminate rivers, lakes, and groundwater with harmful chemicals and heavy metals. Additionally, overexploitation of water sources, particularly for agriculture and urban development, leads to the depletion of aquifers and the drying up of rivers. These human-induced factors, while not as globally pervasive as climate change, can have severe localized impacts on water availability and quality.

Despite these other threats, I maintain that climate change remains the most significant danger to global water resources due to its far-reaching and long-lasting effects. Unlike localized pollution or overexploitation, which can potentially be addressed through targeted policies and technologies, climate change requires a coordinated global effort to mitigate its impacts. The interconnected nature of the Earth’s climate system means that actions in one part of the world can have consequences for water resources in distant regions.

In conclusion, while acknowledging the existence of other threats, I strongly agree that climate change poses the most substantial risk to the world’s water resources. Its global scale, long-term consequences, and the complexity of addressing it make it the paramount challenge in safeguarding our planet’s water supplies for future generations.

Sample Essay 2 (Band 6-7)

Climate change is a big problem for water resources around the world, and I mostly agree that it is the biggest threat. However, there are also other important things that can harm our water supplies.

Climate change affects water in many ways. When the Earth gets warmer, it changes how rain falls in different places. Some areas get too much rain and have floods, while others don’t get enough rain and have droughts. This makes it hard for people to get the water they need. Also, when ice melts in cold places because of global warming, it can cause problems for rivers and make sea levels rise, which is bad for freshwater near the coast.

Water scarcity in drought-affected region

But we shouldn’t forget about other things that can harm water resources. For example, factories sometimes put chemicals in rivers and lakes, which makes the water dirty and unsafe to drink. Farmers and cities also use too much water sometimes, which can make rivers and underground water sources dry up. These problems can be very bad in some places, even if they don’t affect the whole world like climate change does.

Even though these other problems are serious, I think climate change is still the biggest threat to water resources. This is because climate change affects the whole planet and can last for a very long time. It’s also harder to fix climate change because it needs many countries to work together, while other water problems can sometimes be solved by just one country or area.

In conclusion, I mostly agree that climate change is the biggest threat to the world’s water resources. While other problems like pollution and overuse of water are also important, climate change has the biggest impact on water all over the world and is the hardest to solve.
