I see lot's of articles concerning unhealthy food and unsafe practices being promoted by agri-business with their large bank accounts while the FDA and other civil government agencies target small agricultural producers trying to offer healthy alternatives to their well-educated customers that seek out their products. This is a great article that I think provides a fairly good overview of the issue and some sustainable solutions coming out.
I definitely believe that the next major crisis could be food or possibly water. We must begin to develop sustainable lifestyles and systems that accurately steward our natural resources.
