Q5. The fourth global coral bleaching event marks a tipping point in marine ecology. Analyse its scale and causes. Evaluate its repercussions on marine species. (10 M)
Difficulty Level: Medium
Reference: DTE
Why the question Scientists have confirmed that the world’s worst ongoing global coral bleaching event has now affected nearly 84 per cent of the world’s coral reefs. Key Demand of the question The question requires an examination of the global scale and root causes of the ongoing mass bleaching event, followed by an assessment of its ecological impacts on dependent marine species. Structure of the Answer: Introduction Briefly introduce the record-breaking nature of the fourth global bleaching event and its link to rising ocean temperatures. Body Analyse the scale and causes: Unprecedented Ocean warming, El Niño impact, local anthropogenic pressures, etc. Evaluate the repercussions: Collapse of reef ecosystems, biodiversity loss, fishery decline, rise in coral diseases, etc. Conclusion Highlight the ecological tipping point this event represents and the urgency for integrated global reef resilience strategies.
