I think the most important thing is education. There's a non-judgmental way to teach others about the environment. Sometimes using a phrase like . . . "Did you know . . . " is a great way to spread the word about eco-friendly advice.
Also, place REMINDERS around the home and on your computer to keep up-to-date about the environment.

I don't try to do everything. Instead I add one positive behavior until it becomes a part of my lifestyle . . . then I add another when I'm ready. One day, I hope to be an environmental activist. But today I'm just doing baby steps to help the environment.
