Why are mangroves important for coastal areas?
Mangrove forests grow in saline coastal waters and act as a natural barrier protecting coastal areas from severe storms, tidal surges, and soil erosion.
What are the main causes of the depletion of flora and fauna in India?
The main causes include deforestation for agriculture and urbanization, overgrazing, mining, hunting for commercial use, pollution, and industrial expansion.
