hippies wrong again

So my wife and I have been watching a show called "It's not Easy being Green"

This British show is about some couples who buy a farm house and try to live off grid.  This concept has really appealed to me all my life.  The thing is, as I watched this show, I have developed a new environmental theory.

That theory says the whole idea of off grid living is totally selfish and not environmental at all.  The concept of everyone taking care of their own crap, growing their own food, and making their own power is counter productive.  Imagine if everyone in your city dropped a line into the cities water table.  It would be disastorous for both farmers and people to fight over well water.  How much better off as a society are we for sharing water from lakes, and having sewers?

I think that most environmental activists need to really think about stopping the pushing of indepedance.  I think socially it would be a nightmare if we didn't pull together as a society and all help each other out.

Don't think I am against environmental improvements.  I like the thought of using the sun to heat water, harnessing winds and tides to generate power, etc.  I just don't think that it is a good idea for people to think that living off grid is what the goal should be.  I think the goal should be to use what we have wisely.
