I think we need it as a necessity but treat it like a luxuary.Many times we could either,walk,bus or car pool with another.Again,its an north american gluten style of taking more than we need...take for instance water,many leave it running while brushing their teeth,not stopping to think,of the simple little waste of a necessary commdidty,most other continents cant even turn on to drink.Also the biggest holding tank for fuel is the north american car or truck..instead of filling up your tanks,it is said,that the price of fuel would drop,because oil company storage facilities would be full.Gasoline as most commodities in north american go from necessity to luxuary,ussaully with no thought to the reasons why.We leave lights on in our homes,we water grass no animal eats,we throw tons of edible food away daily (as a society or group)..The question should be at what point does gasoline/oil no longer becomes a necessity?
