About 150 years ago we began canning food to extend shelf life in an attempt to end hunger across the globe and make life more convenient.
Many families learned how to preserve their precious harvests. Today, giant factory farms use thousands of chemicals to grow and process our food supply.
Shelf life is longer, but there is still global hunger, and health - of our soil and ourselves - has been severely damaged.
Why are we still doing the same things expecting a different outcome?
