Did you participate in Earth Hour 2008 and turn out your lights on Saturday evening for one hour? We did. I played the Fear Factor board game with my kids by candlelight.
I've tried to take the leap to be more energy conscience but it's a work in progress. For example, I've tried those energy efficient CFL light bulbs but I haven't been able to totally make the switch because I just don't find them bright enough. Living in the Pacific Northwest means it's quite dark for a lot of the year and I really get frustrated with low lighting.
I'm also big on recycling but had to give up composting because it attracted too many rats to our yard. How about you? What steps have you made to help out our planet?
