Q6. Deoxygenation in global lakes reflects the accelerating consequences of both long-term climate change and short-term climatic extremes. Analyse the ecological implications. Suggest long-term mitigation frameworks. (15 M)
Difficulty Level: Medium
Reference: DTE
Why the question: 83% of lakes globally experiencing decrease in surface water oxygen levels, courtesy increasing heat waves Key Demand of the question: The question requires examining how both long-term warming and short-term heat waves are driving lake deoxygenation, assessing its ecological consequences, and proposing sustainable long-term mitigation strategies. Structure of the Answer: Introduction: Start with a brief factual context about the scale and urgency of lake deoxygenation and its climate linkages. Body: Mention how global warming and heat waves affect oxygen levels in lakes. Discuss key ecological disruptions caused by reduced DO, including biodiversity collapse and biogeochemical changes. Suggest broad mitigation ideas including adaptive management, nutrient control, and policy reforms. Conclusion: End with a futuristic and solution-oriented remark stressing integrated action, scientific innovation, and global cooperation.
