You might as well get used to recycling because its in our future. Raw materials are extracted in concentrated form and scattered around the world as waste - in i-pads, in gases, in bottle caps etc. The original concentrations needed for re-usage can only be achieved through strict controls and the use of large amounts of energy (entropy can only be reversed by expending energy). You might think this foolish now, but as key industrial materials (rare earths, copper, etc) become scarce we will have no choice. Think of the current recycling as practice for when things get serious. Or do you think we will find new sources forever?
