Earth Hour 2009

We encourage everyone to participate in Earth Hour, a global climate action event to raise awareness of climate change and to demonstrate a commitment to sustainability. If you wish to participate, simply turn off unnecessary lights, unplug unnecessary electronics, and go on to your patio at 8:30pm on March 28th, next Saturday, to watch the lights turn off around the globe for one hour.
