What sustainability means on a personal level is being able to live in such a way so that everyone everywhere has the ability to live and have their basic needs met.  It really is a justice issue, as much as an economic one.  We just know that one person in the life boat eating most of the food can't be tolerated.  So if we are all to get out of this alive - better yet have healthy and meaningful lives - fairness and equity are essential.  

We have known it for years.  We have too much stuff.    To get an idea of why have a look at this great video on the The Story of Stuff website.  Who thought economics could be so simple?  

Who knew that real estate and "stuff" were so intertwined?  Basements, crawl spaces, closets, garages, houses that are twice as big as they were 40 years ago - that's where the stuff is, and when it gets to be to much stuff, we stuff it in a garbage bag and have the stuff picked up at the curb.
