Planetfesto.org is an environmental education and action movement created on 2/14/2007. The goal is for individuals worldwide to create a virtual ribbon of 6" pieces--long enough to circle the earth. (nearly 263,000,000 pieces required). Each "piece" of the ribbon is made up of a photograph or drawing representing why the person loves the earth, a brief statement of why they love it, and a pledge of individual action. The ribbon creates an evolving, collaborative manifesto of love and action.
Planetfesto is unusual in environmental movements as it is takes a higher view on the problem--that what is needed is a new era in our relationship with the planet. On the site, there is a quote by Wendell Berry: "What we do not love, we will not save."
Jody Ouradnik has created a video introducing you to the Planetfesto project. It also walks through adding your own ribbon segment.
