What do you think are the biggest challenges your project is facing right now? *

The problem?
Simple ignorance. Unfamiliarity. Fear. Laziness.  Aversion to working with 'wastes'.  Information assymetry. Myths, disinformation, risk aversion, a Zeitgeist of apathy, disbelief, defeatism, lack of trust, lack of experimentation, systemic patron-client discouragement, bad public policy, lack of incentives, withholding of key information motivated by a desire for profit and personal gain. All psychological, none technological or material.

Question

In other words "if it is so damn good, and so damn easy,  why isn't everybody doing it?"
