I am interested in developing a more environmentally friendly lifestyle.  I also realize that I need a systematic process of reducing  maladaptive behaviors and adopting more ecologically consitant behaviors.  I understand that this is a a very behavioral approach to this process, but it makes sense for me. 

So.....where do I start?  I listened to a podcast about a family in New York City attempting to live a zero impact lifestyle.  They went through steps.  Does anyone know the steps they took and how?
