So I've been thinking about what I can do to start the ball rolling on this new years resolution. What would be the best approach? How can I do what I want to do and try and reach as many people as I can.

The recent report concerning global warming basically says that humans are "most likely" the cause of global warming. To help do my part, I challenged my friends and family via my personal blog to try to reduce energy consumption which ultimately reduces CO2 emissions. I set up a flickr photogroup so that people could post photos of themselves changing lightbulbs, or other fun things related to this effort. Every incandescent lightbulb replaced can reduce CO2 emissions by 1/2 ton over the lifetime of the bulb.
