Fifty years ago ninety percent of our food was grown or produced locally. Today ten percent of what you find at most big grocery stores is locally grown or produced and the rest comes from great distances.
It must have a lot to do with advances in transportation and refridgeration as well as the rise of giant corpoations and loss of small farms and producers and now globalization as well. When, and we will one day, experiance another or multiple catastraphies with regards to world war, riseing sea level, water shortages and or drought, climate change, world depression etc we would be much better off limiting our countries population growth now, growing enough food in our own country locally and takeing care of our own local enviroment to keep what's left of our fertile land and precious water sheds from being clear cut and or paved over and built on. It's not fun being packed in like rats in our dirty crime ridden cities. It's suffucateing. That is a model the rest of the world should be following. With so many countries buldgeing at the seams with uncontrolled population growth many of the problems are beginning to resemble some thing of an apocoliptic horror movie. Kinda like while Rome was burning and they just kept the big party going or sheep running off a cliff. Maybe we will wake up?
