Fighting for what people believe in as far as the green efforts is concerned may be commendable. But just like anything else, the whole initiative should start from the very grounds to which established sites will originate from.
People can start out headquarters and places to play office and home base towards the whole project or activity. However, good practices should be done immediately after and before launching the whole campaign. Failing to do so will surely make negative marks and question the whole intent of the drive to go green and help the world.
