Topic – geographical features and their location- changes in critical geographical features (including water bodies and ice-caps) and in flora and fauna and the effects of such changes.
2) What do you understand by coral bleaching? Discuss the factors responsible for destruction of corals?(250 words)
Why this question
The article highlights IPCC report and discusses the significance of coral reefs and the factors responsible for their destruction. Coral reefs and the reasons why they are facing threats is important for GS1
Key demand of the question
The question expects us to first explain what coral bleaching is and the various factors that cause coral bleaching. We can also provide the impact of diminishing corals and what we can do to save them.
Discuss – Here, in our discussion we need to explain coral bleaching and the reasons for the same.
Structure of the answer
Introduction – Mention that IPCC report has pointed out the grave risk of loss of coral reefs if corrective actions are not taken. Clive Wilkinson of the Global Coral Reef Monitoring Network says 10% of the Earth’s coral reefs have been reduced to skeletons, another 30% are in a critical condition and a further 30 are under severe environmental stress.
Body – Explain what coral bleaching is. Discuss the reasons for the same such as overfishing, increased Temperature of the oceans etc. Discuss the impact of destruction of coral reefs – here we need to highlight the immense productivity of such reefs and its destruction would have immense impact of marine ecosystem etc. Discuss the steps required to address the destruction of coral reefs – devise policies to provide protection to existing carbon sinks such as corals along with developing an adaptation frameworks for others. Reducing emissions will be critical here.
Conclusion – Emphasize on the importance of corals and discuss the way forward.
