Why do it? Exposed to the earth's atmosphere,  aluminum combines with oxygen to form a  protective surface film which inhibits further  oxidation of the aluminum.  Unlike steel or iron alloys, aluminum will not  continue to oxidize (rust) once this protective  layer is formed. This natural oxide is  extremely thin and loosely adhered to the  aluminum surface, however, and is easily  removed by handling.  Anodizing is a process which thickens the  natural oxide film resulting in a heavy  aluminum oxide film of controlled thickness  having the hardness similar to that of a ruby  or sapphire.
