Mangroves act as natural buffers against coastal erosion and storm surges.
- True
- False
Answer: True
Mangrove root systems stabilize shorelines, reduce wave energy, and protect inland areas from cyclones and tsunamis.
Environmental Monitoring is conducted only before project implementation as part of the EIA process.
