The topic of biodiversity and ecological balance has been increasingly prominent in IELTS Writing Task 2, appearing in various forms across recent test papers. Based on analysis of past exam questions, this theme has shown up approximately 15-20% of the time when environmental topics are tested, making it a crucial area for IELTS candidates to master.
importance of biodiversity for ecosystem health has become particularly relevant in recent years, with questions focusing on conservation, species protection, and environmental sustainability.
Question Analysis
Some people believe that protecting endangered species should be a priority, even if it impacts economic development. To what extent do you agree or disagree with this statement?
This question requires candidates to:
- Take a clear position on the priority of species protection
- Evaluate the trade-off between conservation and economic growth
- Support arguments with relevant examples
- Consider both environmental and economic perspectives
The balance between protecting endangered species and economic development
Band 9 Sample Essay
The preservation of endangered species is undoubtedly one of the most critical environmental challenges we face today. While some argue that economic development should take precedence, I strongly believe that protecting endangered species must be prioritized, even when it poses challenges to economic growth.
First and foremost, importance of biodiversity in maintaining ecosystem balance is fundamental to our planet’s survival. Each species plays a vital role in maintaining ecological equilibrium, from pollinating plants to controlling pest populations. When we lose a species, we risk disrupting entire food chains and ecosystems, which can have far-reaching consequences for both nature and human society. For instance, the decline of bee populations globally has already begun to impact agricultural productivity, demonstrating how species loss can actually harm economic interests.
Moreover, The importance of biodiversity in combating climate change cannot be overstated. Many endangered species contribute to natural carbon sequestration and help ecosystems adapt to changing environmental conditions. Protecting these species is therefore not just about conservation but about ensuring our planet’s long-term sustainability. The preservation of mangrove forests, home to numerous endangered species, provides natural barriers against coastal erosion and storm surges, offering economic benefits through disaster prevention.
While economic development is important, it need not come at the expense of species protection. Sustainable development approaches can create win-win situations where both conservation and economic growth coexist. For example, eco-tourism around protected species habitats can generate significant revenue while ensuring species survival. Costa Rica’s success in this regard demonstrates how why biodiversity should be prioritized in environmental policies.
Band 7 Sample Essay
In today’s rapidly developing world, the conflict between protecting endangered species and promoting economic growth has become increasingly apparent. In my opinion, while both aspects are important, the preservation of endangered species should generally take priority.
The main reason for prioritizing species protection is that once a species becomes extinct, it is lost forever. This irreversible loss can have serious consequences for ecosystem stability. For example, when top predators like tigers disappear from an area, it can lead to overpopulation of their prey species, which in turn affects vegetation and the entire ecosystem balance.
However, I acknowledge that economic development is crucial for human welfare. Many communities depend on activities that might threaten endangered species. Nevertheless, there are often alternative approaches to development that can protect both economic interests and wildlife. For instance, sustainable forestry practices can maintain jobs while preserving critical habitats.
importance of protecting endangered species in a changing world is demonstrated through various successful conservation projects that have actually boosted local economies. Wildlife sanctuaries and national parks often generate significant tourism revenue while protecting endangered species.
