The Sahara Desert, N. Africa, is often given as an example of a huge area of shifting sand dunes. Though, actually, the dunes form only a small part. The main part consists of rocky 'hamada': high, largely barren, hard, rocky plateaus, with very little sand.
Sand dunes in the Sahara are just a fact of geography. They are just piled up and shifting sand with no economic value. Beach sand dunes like those in PEI Canada are habitat for some little creatures like ground nesting birds. And good places for picnics.
