Nice question... Let's us consider we r making fuel conservation a habit.. Actually it is not happening... Let us consider... Let's see what happens.. If we just consider.. That we r conserving fuel..
Before people used to suffer , by improper medication.. After some years technology developed.. We got proper medication...
Next.. People suffered lack of food... Later technology developed.. We got many methods to get the food..
Later we may also.. Get.. The problem of fuel..
But we don't have any methods to prepare it..
When their is no way for preparation.. Let us conserve it... If we conserve ( as starting I told )
We can live happily.. As the pollution decreases.. Pollution leads to may diseases.. So.. Let us conserve fuel.. And make it as a habit.. And show light for the future generations.
