Waste is Part of living

Waste is part of living!Any thing that grows has to waste lots..Thinking,pleasure,sufferings etc as emotional wastes and substance waste..We waste our energy,food,materials and what not.Finally some may come to a point where the whole life becomes a waste...But at molecular level there is nothing as Waste and philosophically there is nothing called Waste!.How do we mange the waste we generate?it varies..The greed of ours is a prime reason for waste.
