Natural sand dunes play a vital role in protecting our beaches, coastline and coastal developments from coastal hazards such as erosion, coastal flooding and storm damage. Sand dunes protect our shorelines from coastal erosion and provide shelter from the wind and sea spray.

Answer 2

Answer:

well

Explanation:

Sand dunes offer essential ecological habitat as well as natural coastal defense against storm surge and strong waves, avoiding or reducing coastal flooding and building destruction. They serve as sand storage sites as well, delivering sand to beaches that have degraded.

so, what would happen is they were destroyed?

Areas of bare sand are left exposed to wind erosion and frequently turn into blowouts after damage to the dune vegetation. Large portions of the foredune system might become mobile and travel landward with more damage.
