I'm keeping it short, u can elaborate. There ary many problems that arise because of careless use of the resources that provide us with energy.Like if we take coal, it is being used so carelessly that it will get exausted in abut 50 yrs frm now as estimated by the scientists. Coal is a source of energy in factories and it also provides us with products like coal tar etc which are equally important in our daily life. If the resources like petroleum and coal are exhaysted then this will badly affect our daily life as they have become so common now, considering their usevin cars, factories and our houses we need to save them...
