Selvam from Cuddalore district, Tamil Nadu, shared that his village was less affected by the 2004 Tsunami compared to nearby villages due to the presence of mangrove forests. This surprised Sarita, Shabnam, and Shijo. They wondered if mangroves were protecting the village. Can you help them understand this?
Mangrove forests protect coastal villages from natural disasters like tsunamis and cyclones by acting as natural barriers.
The dense network of mangrove roots and trees slows down strong winds and waves during storms and floods, reducing their destructive force before they reach human settlements.
The Sundarbans mangrove forests, as described in the chapter, protect inland areas by absorbing the energy of waves and winds.
Mangroves also absorb carbon dioxide from the air and release oxygen, contributing to environmental health.
This is why villages with mangrove forests nearby experience less damage during tsunamis compared to those without such natural protection.
Explanation
Section 12.9 of the chapter specifically discusses the Sundarbans mangrove forests and states that 'The Sundarbans protect us by slowing down strong winds and waves during storms and floods.' This real-life example from Tamil Nadu demonstrates the protective function of mangrove ecosystems, which serve as natural barriers against ocean disasters.
Solution Steps
