Martygras,
Thats the key point! However, when you consider that our soils are so depleted of nutrients and saturated with herbicides and pesticides all of which results in minimal nutrients in the produce grown, any non polluting method should be carefully considered. If that method actually can grow nutritious produce at a competitive price point, then it doesn't matter too much what it is called. Most of our health problems are caused by an overabundance of chemical laced vitamin and mineral deficient foods. Add in all the unnatural genetic modifications and extensive processing for corporate profit, it won't be long before that field grown broccoli is not suitable for human consumption.
