New Trends in Farming?

Kristen, who is a more devout cook than I am, and even a more fervent recycler (although I recycle anything I think I can get away with putting into the recycling bags), has been finding some interesting articles on urban and sustainable farming.
As a descendant of farmers, and as a person who is very familiar with the high quality possible in home-grown food, I'm delighted to see more and more mainstream coverage of organic foods on small farms and in gardens. And, as this author suggests, the rising price of oil may prompt more farmers to choose to get away from agribusiness-style farming.
