Not only big pharma but also look at the world as a whole.. Grain is huge in USA and many countries...what would all the grain growers and cereal wtc companies do? Yes, many could convert to better, but better is actually, fresh food..what would happen to all the crisp manufacturers, bread suppliers.
Countries have plowed billions in to producing carbs and foods...
I personally would love the fresh foods back.. I love watching places like Vitnam etc or China for seeing them having giving ants/bugs as a delicacy to friends...they all value the protein in them.
