contrary to what many say, humans did not invent waste; nature did...the difference, however, is that nature has mostly perfected its "waste management system."... all forms of waste are eventually consumed, used and recycled in a chain of matter and energy flow. but humans have persistently mismanaged their waste, creating new types at an increasing pace and in excessive quantities without establishing recovery mechanisms that enable their flow and circulation back into the cultural/natural systems. the key to this disparity might be our cultural constructs of and taboos regarding waste. these have largely interfered with wise management, confusing real and percieved dangers.
