The 2004 Tsunami made people realize that mangroves can serve as a reliable safety hedge against coastal calamities. How do mangroves function as a safety hedge?
- (a) The mangrove swamps separate the human settlements from the sea by a wide zone in which people neither live nor venture out
- (b) The mangroves provide both food and medicines which people are in need of after any natural disaster
- (c) The mangrove trees are tall with dense canopies and serve as an excellent shelter during a cyclone or tsunami
- (d) The mangrove trees do not get uprooted by storms and tides because of their extensive roots
Show the answer and explanation
Answer: (d) The mangrove trees do not get uprooted by storms and tides because of their extensive roots
Dense, extensive roots hold mangroves in place and break the force of waves.
Why the others are wrong
(a) The buffer works physically, not because people stay away.
(b) Food and medicine are not the protection.
(c) Mangroves are not tall shelters.
The trap
None.
🔒 Mangroves: bio-shield (Pichavaram villages were spared in 2004).
