To start with a bit of trivia, the first Earth Day took place in 1970, 40 years ago.
In 2010 you can support Earth Day virtually, with your feet by joining the Climate Rally on The Mall in Washington DC.
You can also participate with smaller gestures like taking a shorter shower (best to take it alone I guess), using a reusable water bottle for a while rather than build a plastic mountain
A number of other ways include Recycling your wine corks. I noticed that Whole Foods allows you to drop them as you shop.
You could also watch the trailer for Dirt, the Movie above…
If my back is not hurting anymore I will leave my car in the parking lot and walk instead.
Happy Earth Day 2010 for Green Day # 124
