Q5. “Marine pollution has become the invisible crisis of the Anthropocene”. Discuss the major sources and ecological impacts of ocean pollution and suggest a comprehensive strategy to address it. (15 M)
Difficulty Level: Medium
Reference: DTE
Why the question: The escalating problem of marine pollution in the Anthropocene era, its root causes, ecological consequences, and the need for an integrated global and national response framework. Key Demand of the question: The question demands identification of key pollution sources, analysis of their multidimensional ecological impacts on marine ecosystems, and formulation of a holistic mitigation strategy integrating policy, technology, and international cooperation. Structure of the Answer: Introduction: Define marine pollution and explain why it is termed an “invisible crisis” in the Anthropocene due to cumulative, diffuse, and long-lasting human impacts on oceans. Body: Major Sources: Briefly describe land-based runoff, agricultural effluents, plastics, oil spills, and oceanic industrial activities. Ecological Impacts: Explain how pollution affects biodiversity, coral bleaching, food webs, and oceanic carbon cycles. Comprehensive Strategy: Suggest multi-level actions—strengthening global treaties (MARPOL, UNEA Plastics Treaty), national marine litter policies, waste-to-energy initiatives, community-based coastal governance, and scientific monitoring systems. Conclusion: Conclude by stressing the need for collective ocean stewardship, sustainable blue economy principles, and a science-policy interface to restore marine health.
