What are barrier islands? why are they so attractive for human development and why are human structures built there so vulnerable?

Barrier island are formed by the deposition of sand along the stretches of main land coast and serve as a barrier for strong storm waves. They are beautiful but unstable hence, human structure development is not safe on these islands.

Explanation:

Barrier island are formed by the deposition of sand along the stretches of main land coast and serve as a barrier for strong storm waves. These islands are not stable and keep on changing their reduced level based on the changing level of sea and long shore level.

Due to aura of natural landscape, lot of recreational and residential developments are carried out on barrier island but since these islands are not stable due to the shifting sand beneath the island such human structures are not safe.

Barrier islands are the piece of land which is usually flat and is surrounded by water from all the sides.

This type of land is prominent for the development and human interventions because they are flat and can be easily developed.

These land are sometimes covered with the sand dunes. The land becomes more susceptible to floods and storms.

This is because the island is being used by the human beings.
