Start anywhere at anytime!!
I'm an active member of www.freecycle.org in Frederick, MD, USA. Every city in the U.S. and each community has an active group on Yahoo! that offers things they no longer use AND it's free. Instructions online.
I enjoy going green to save and maintain our environment. I think it's important to be aware of recycling and proactively doing it. Re-using if you have to and renewing energy (turn off appliances not in use, for example saves energy).
Green cars exist. You do not have to buy a green car just to be green. There are ways online on how to save on gas.
Anyone can join from anywhere. It would be ultra cool to hear from others in other countries in how they manage.
Come on in!!
