Waste is a human concept. Nowhere else in nature can you find systems that incorporate this belief. Just exactly when and how mankind created this habit is a mystery, although I’m sure Scientist’s would likely link it to the advent of agriculture or some such revolutionary occurrence. Waste is a subjective idea, proven by the age-old adage “one man’s trash is another man’s treasure”, and it’s a notion that we have learned to merge with our beliefs of worth and value. Through this amalgamation we have come to create a concept of waste that can mean many things, but always has a negative connotation.
