I saw Earth Hour as more of an action geared toward awareness, if not for us as adults (using that term very loosely) then for school children who were given an action to attach to the cause. This makes them aware of global warming at a very young age, far younger than any of us here. If this one small action can lead to our younger generations making green activities part of everyday life rather than an option that we do or don't choose to partake in, the Earth will be a better place for it. ..and boko, its too bad someone felt the need to produce all of these items. these are the individuals that need the awareness beat into them the most. for what its worth, i think the billboards, t shirts and posters were unique to your neck of the woods and there were none of these in all of KW to my knowledge.
