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.
