Amusing way to put it. Not really the case, as plants are not 'made' of the elements they consume biologically, and plant stocks are designed to be resistant to pathogens better than the 'wild' varieties.
Really? But these plants are not being grown for aesthetics but as a food source. Nutrition value (read vitamin, mineral content, et al) of contemporary produce is considerably less than it was 50 years ago. If interested see a sample low-tech Scientific American article on the subject.
And for the sociology: what percentage of the population are responsible enough to take the now necessary dietary supplements to maintain a healthy, productive physiology?
