Just a little bragging: My daughter and I planted most of the plants you see in the following picture:
http://www.co.clark.nv.us/parks/wetlands/Wetland's_Homepage.htmAll of the students in environmental courses at UNLV were offered extra credit for helping out one day, and a hundred of us showed up. They drained the ponds significantly, assigned ten member teams to an area, gave us shovels and seedlings and told us to start planting. Now, normally I don't mind being surrounded by 19 year old college girls. But on this particular day, it was my daughter and me, and 8 girls saying, "Eeew! Gross! I don't want to touch that!"
So I turned into a hole-digging machine, my then 6 year old daughter turned into a hole-filling machine, and the two if us replanted the largest section of the local wetlands faster than anybody else.
A lot of volunteerism is just so impersonal. We help out homeless families through the Unitarian Church, and, although we know we've made a difference, we never see them again. But my daughter and I can still go to the local wetlands and see our handiwork.
You obviously are more dedicated than I am. I don't ride my bike outside the neighborhood as it's too dangerous, when it's 100 degrees at nine AM walking to the garage can be exhausting, I dry my clothes in the summertime outside but have to do it in secret because of the HOA, and the only "reusing" of household waste water I do is a general adherence to the "If it's yellow let it mellow..." philosophy.
Therefore, the only hint I can offer is this: don't shut up about it, especially the easy stuff. I have gotten more people to switch to CF lighting than I ever thought possible because I talk about it at every possible opportunity, and NEVER fail to mention the cost-effectiveness I have personally seen. I'm sure you already know that, but you also never know who's reading this.
