I love this idea.  The world is needing some big ideas that change how
we produce and consume.  We have so much in America, if we try to
recreate a bunch of “Americas” all over the world we are simple going
to run out of resources.

I love love love the idea of taking processes and finding ways to use
the waste. Waste not want not applies on a “earth” level as well.
