I try to be a little bit of an eco-warrier when I can, but I know I could do a much better job. However, tonight we can all do something simple to make a bit of difference — celebrate Earth Hour.

Earth Hour is an initiative by the WWF (World Wildlife Fund, not the nasty wrestlers) to bring awareness to carbon emissions and energy usage across the world. From 8 p.m. until 9 p.m., we’re all encouraged to turn off the lights. In participating cities, even businesses and restaurants are joining in. It’s easy, and it’s small, but it helps.

And come on, can’t you think of something fun to do in the dark for an hour?
