Also, I have visited an urban farm business in Detroit (Hantz Farm:http://www.hantzfarmsdetroit.com/). The president advised me that people still make their decision on price/quality when they buy foods although the movement of local product consumer are getting bigeger. Friend of mine who purchases a locally delivered boxes of vegetables told me that they buy local because of its quality and price as well as the fact that they can contribute to the local business.
Japan has been trying to develop its IT on agricultural production, and one TV program broadcasted Netherlands greenhouse techonology。Netherland now is the second largest agriculture country in the World, and the main reason is their sustainable greenhouse technologies. Although the size of land they own to produce that amount of product is not as big as their production, their technology has brought enormous technology advantage in the competitive free trade market.

People have been trying to purchase local products, but I think there are millions of opportunities for business to acquire this market by developing its productivity for its price and quality. I think the greenhouse technology will be one of big game changeable item sometime really soon.
Go for it,
