IELTS Writing Task 2 Topic: "Is deforestation the biggest threat to biodiversity?"

Model Answer:

In recent years, the rapid rate of deforestation has raised concerns about its impact on global biodiversity. While it is undoubtedly a significant factor contributing to the loss of species and habitats, other factors such as climate change, habitat fragmentation, and pollution also play crucial roles. This essay will examine whether deforestation is indeed the most significant threat to biodiversity and consider alternative factors that may pose an even greater risk.

Firstly, it is essential to understand the scope of deforestation. Large-scale deforestation has occurred due to agricultural expansion, logging, urbanization, and infrastructure development. These activities have led to a reduction in forested areas, which are vital for the survival of countless species. As a result, many plants and animals have lost their natural habitats and face the risk of extinction.

However, deforestation is not the sole threat to biodiversity. Climate change, driven by human activities such as burning fossil fuels and deforestation itself, has resulted in rising temperatures, extreme weather events, and shifts in ecosystems. These changes have disrupted food chains, altered habitats, and reduced the available resources for many species, leading to a decline in biodiversity.

Additionally, habitat fragmentation is another factor that endangers biodiversity. As human populations grow and expand into natural areas, forests are divided into smaller patches of land, preventing species from moving between habitats. This isolation can lead to the formation of separate populations with reduced genetic diversity, making them more susceptible to environmental changes or disease outbreaks.

Furthermore, pollution poses a considerable threat to biodiversity. Chemicals and waste released by industries and agricultural activities have polluted water sources, soil, and air, affecting the health of plants and animals. The accumulation of toxic substances in ecosystems can lead to the decline or extinction of species unable to adapt to these new conditions.

In conclusion, while deforestation is undoubtedly a significant threat to biodiversity, it is essential to recognize that other factors, such as climate change, habitat fragmentation, and pollution, also play crucial roles in the decline of global biodiversity. To effectively address this issue, it is necessary to tackle these interconnected problems through sustainable land use practices, conservation efforts, and policies aimed at reducing human impact on the environment.
