Why do we have a shape to wing?

Usually wings are designed in a different varieties based on the where it is used. Every wing design will not have the same functionality. Each and every design is unique and hence designed to serve the particular purpose. When it comes to wings, the first thing that comes to our mind is the airplane wings. The Airplane wings are designed in a way to make the air move faster over the wings which creates less pressure on the top of the wing than at the bottom of the wing. This difference in pressure creates a force which lifts the wing up in the air.
