"The key.. will be a new public awareness of how serious is the threat to the global environment. Those who have a vested interest in the status quo will probably continue to be able to stifle any meaningful change until enough citizens.. are willing to speak out."

There is an old proverb to the effect that 'all those who open their mouths, close their eyes!' The purpose of silence and solitude is to be able to see and hear. Control rather than no noise is the key to silence. James saw clearly that the person who could control his tounge is perfect (James 3:1-12). Under the Discipline of silence and solitude we learn when to speak and when to refrain from speaking.
