The importance of sand dunes to the coastline

Sand dunes are natural barriers against the powerful waves and windy storms. Beach dunes are also a rich habitat for specific vegetation and wildlife.

The biggest and most common threats to sand dunes have a human origin - the construction of houses and condos, car parks, roads, piers, groins, as well as sand mining and farming are the worst enemies of these sand banks.

The sea level rise - a direct result of global warming - is also destroying these extraordinary natural fences. But again, the human touch is always present.
