Tonight (Saturday, March 29th) from 8pm to 9pm I will be celebrating Earth Hour by turning off all of my lights and electronics.
On it's surface it appears to be such an insignificant action, and I acknowledge that it is. But ponder this: for an hour I will not be watching television or working on the computer. Now multiply that by the millions of households that are expected to celebrate Earth Hour and it begins to get significant.
At the very least it gets people thinking about how to reduce our energy footprint, and that is a good thing. Make sure to Sign Up if you plan to join (so they can get a good count of participants). Canada is kicking the ass of the United States in participation so far, so more people would be great.
