Writing Topic: Is deforestation the biggest threat to biodiversity?

Model Answer:

In recent years, deforestation has emerged as one of the most significant threats to global biodiversity. While it is important to acknowledge that other factors, such as habitat destruction and climate change, also contribute to the decline in biodiversity, this essay will argue that deforestation remains the primary cause. In order to substantiate this claim, three main points will be discussed: the direct impact of deforestation on species loss, its contribution to climate change, and the subsequent impact on ecosystems.

Firstly, deforestation directly leads to the loss of habitat for a multitude of species, resulting in an alarming rate of extinction. The Amazon rainforest, for instance, is home to a vast array of flora and fauna, many of which are endemic to the region. As these forests are cleared for agricultural purposes or logging, the native species lose their homes and face the risk of extinction. According to the World Wildlife Fund (WWF), approximately 137 plant, animal, and insect species are lost every day due to deforestation.

Secondly, deforestation significantly contributes to climate change, which in turn exacerbates the threats to biodiversity. Forests play a crucial role in absorbing carbon dioxide, a greenhouse gas, from the atmosphere. When trees are cut down and burned or left to decompose, the stored carbon is released back into the environment, contributing to global warming. Moreover, deforestation disrupts the water cycle by reducing transpiration, which can lead to drought conditions that negatively affect both plant and animal life.

Lastly, the indirect impact of deforestation on ecosystems further underscores its threat to biodiversity. The destruction of one habitat often leads to a cascading effect on neighboring ecosystems, as species are forced to move in search of new homes. This can result in overpopulation and competition for limited resources, ultimately leading to further loss of species.

In conclusion, while it is true that deforestation is not the sole threat to global biodiversity, it remains one of the most significant factors contributing to species loss and ecosystem disruption. The direct impact on habitat loss, its contribution to climate change, and the subsequent ripple effects in surrounding ecosystems all demonstrate the urgency of addressing this issue. Efforts to mitigate deforestation through sustainable forestry practices, reforestation initiatives, and international cooperation are essential to protect our planet's rich biodiversity for future generations.

Overall, the candidate has provided a comprehensive response to the question, demonstrating a clear understanding of the topic and supporting their argument with relevant examples. The essay is logically structured, with each main point introduced, explained, and concluded. The grammar and vocabulary are generally accurate, though there are some minor errors that could be addressed for further improvement. Therefore, based on IELTS scoring standards, this answer would receive a Band Score of 8, reflecting a high level of competence in language use and an ability to respond appropriately to the given question.
