The hour I spent with a group of Columbia Alumni to clean up the small habitat for spawning fish and birds by Lake Ontario and turning out all the lights at my house between 8-9 PM sounds insignificant compared to my (un-intentional) daily contribution to climate change. So, how can I distribute the impact of Earth Hour over a year? Why not declare an Earth Year?!
In privileged places such as North America success of each cause relies heavily on how well people behind it can make the cause look, seem, sound cool and fun. Image is everything. Look around you, Green as a color, Green as an adjective, or being Green as a verb has become trendy. So, it should be easy to instill a Green culture.
Not so easy.
We are used to the "Good Life". Partly due to this, conserving, unless for short period of time, such as 1 hour per year, may not be something that comes naturally. Unless the media does its part and brain washes us. With the unlimited band width in our daily lives, media can turn us into Green junkies. I doubt they do that, for reasons that make an interesting topic for another time and blog.
All in all we will continue splurging.
