Which of the following is an effective protection against cyclones and tsunamis?

Mangrove forests give effective protection against cyclones and tsunamis by absorbing wave energy along the coast.

Shrimp farms actually replace mangroves and weaken natural coastal defence.

Building walls give only rigid, localised protection and can be overtopped or breached by large waves.

Since mangroves are the effective natural shield, none of the above does not apply.

Mangrove roots slow incoming water, trap sediment and stabilise the shoreline.

Many coastal communities suffered less damage where mangrove belts stayed intact.
