Topic: Environment Conservation
Q6. Examine the role of methane in climate change and discuss strategies to reduce methane emissions as part of global environmental conservation efforts. (150 words)
Difficulty Level: Moderate
Reference: Indian Express
Why the Question:
Methane is a potent greenhouse gas with a significant impact on climate change despite its shorter lifespan compared to CO2. Understanding its role and strategies to mitigate its emissions is crucial for environmental conservation.Key Demand of the Question:
Analyze how methane contributes to climate change and suggest ways to reduce its emissions as part of global conservation strategies.Structure of the Answer:
Introduction:
Introduce methane as a key greenhouse gas with a higher heat-trapping potential than CO2, contributing to about one-third of global warming since the Industrial Revolution.Body:
First part: Role of Methane in Climate Change
- Methane’s short atmospheric lifetime but high global warming potential.
- Major sources: agriculture (livestock), wetlands, and the energy sector.
Second part: Strategies to Reduce Methane Emissions
- Improving methane management in agriculture (manure management, dietary changes for livestock).
- Fixing leaks in the oil and gas industry and updating faulty equipment.
- Regulation and policies like the European Union’s mandate to monitor and reduce methane emissions.
Conclusion:
Reducing methane emissions is a critical component of global climate change mitigation, and simple strategies such as improved equipment maintenance and better agricultural practices can make a significant impact on environmental conservation.
