Stephan:   This is some wonderful good news; it offers an alternative to the chemical and poison driven agriculture model that dominates our world now. It also offers an answer to the vast youth unemployment problem we have in our inner cities, as well as eliminating a great deal of pollution arising from trucking food across the country. It is not an entire solution to the poison model, of course, but it could go a long way towards ameliorating the toxic web in which we are now trapped. The article has one major flaw: it's assessment of costs, does not include any of what I have mentioned above and, therefore should be disregarded as a criticism. Click through and look at the video, and listen to these young people talk about what they are doing.
