In Kerala flood due to heavy rain will be immediately followed by drought very soon.
In the light of 'wet land conservation', evaluate this problem.
How does urbanization affect the wet land flora and fauna?

Explanation

The wet land is used for water storage, rain water harvesting, flood prevention, prevention of soil erosion etc. Indiscriminate filling of wet land for human settlement will destroy the flora and fauna of the area and thus it affects the biodiversity of that area. So there is no storage of water during rainy season resulting in drought.
