One has to discuss the various reasons for degradation of the lake ecosystems in India and provide the measures for safeguarding the same.
Discuss – This is an all-encompassing directive – you have to debate on paper by going through the details of the issues concerned by examining each one of them. You have to give reasons for both for and against arguments.
Structure of the answer:
One can start off with the importance of lakes in a given environment. Further substantiate it with the context of the Wular lake itself.

- Dumping of the solid waste, sewerage etc.
- Industrial and residential effluents from the cities that discharge into the lake
- spread of the invasive alligator weed is slowly destroying the beneficial vegetation growing in the lake

How can this be overcome?
Conclude with a way forward.
