Q6. What are the main causes behind the recent mass coral loss in the Great Barrier Reef? How do climate-induced and biological stressors interact to intensify reef degradation? Suggest long-term strategies for coral reef conservation. (15 M)
Difficulty Level: Medium
Reference: DTE
Why the question: The 2025 AIMS report highlighted the most severe coral decline in four decades in the Great Barrier Reef, driven by mass bleaching and compounding ecological pressures, making it a critical global environmental concern. Key Demand of the question: The question requires identifying the primary causes of recent coral loss in the GBR, analysing how climatic and biological stressors interact synergistically to worsen degradation, and proposing comprehensive long-term conservation strategies. Structure of the Answer: Introduction: Mention recent sharp coral loss and how it reflects broader marine ecosystem vulnerabilities due to climate change. Body: Causes: List distinct and recent causes including marine heatwaves, cyclones, disease, and crown-of-thorns starfish outbreaks. Interaction: Explain how climate change-induced stress worsens biological threats, creating feedback loops. Solutions: Suggest long-term strategies such as climate mitigation, heat-resilient coral restoration, better marine governance, and community-led protection. Conclusion: End with a brief line on the urgent need for integrated global action and scientific resilience to safeguard coral reef ecosystems.
