Coastal sand dunes are threatened by development especially tourism development. Even without the development the large numbers of people that may walk across dunes may upset the balance and cause erosion.
The coastal strip between Alexandria and Alamein has been completely devoured by tourist resorts, and large expanses between Alamein and Matruh have been, or are in the process of being converted to resort use. The main components of the coastal environment which are being decimated by these developments are the littoral oolitic sand-dunes.
