Decisions, decisions...

I've been thinking about what I want to blog about and have come down to three topics: cause marketing, medical news, or 'going green'. Although I haven't yet chosen, I'm sort of leaning towards 'going green'. I'm not a complete, or really even partial, tree hugger, but I have an interest. I Insist on using natural light when available, have and use reusable totes whenever I go shopping, refuse to use water bottles, use cold water whenever doing laundry, and always try to unplug any unused appliances. And, I am interested in learning about what more I can do to help. However, before I make a final decision on my chosen blogging topic, I want to be sure it's something I really want to learn more about. I did some further reading here:

Anyone thinking I should do one of my other aforementioned topics?
