I recently watched an absolutely amazing and compelling video called "The Story of Stuff" I can guarantee you that it is worth investing 20 minutes of your time to watch the movie (you can also download it).
I've even written a blog post, "Build a better way" based on some of the issues it raised for me.
There are so many aspects of this: how we consume (which Colin, aka No Impact Man talks about a lot), how we design and create things, how we consume, how we waste and very importantly, how our economy is structured (which we've raised a little here before).
There are also discussions of triple bottom lines (and counter arguments).
The big question is this: what can and should our alternative economy look like if we significantly reduce consumption?
Remember, the current economic model was created, and we have the opportunity to create a new one.
