The hippies take up farming...

Seems like somewhat of an overly idealistic approach to the situation if you ask me - hoping for a day in which 25% of the population are once again farmers (the current figure for America is something like 0.7% if the figures I came up with in Google are accurate).

I tend to think that a lot of modern farming involves some unsustainable practices, but I'm not sure this is the way to go. But, then again, I tend to like renewable energy systems and employing those to do useful things. Even with a lot of renewable energy involved, you'd still need to do something about fertilizers and soil erosion issues though.
