I've actually attempted to survive in the wild eating just wild plant based foods. I assure you that without intensive agriculture there isn't much available and what is available is tough, bitter, sour, and fruits are very small and mostly seed. Those big juicy apples, plums, peaches, grapes, and pears you see in your local supermarket just don't exist in the wild. Wild berries and grapes are about the size of a small pea and mostly seed. Wild plums are about the size of a shelled almond and the flesh is about 1 mm (1/32") thick and covered with a very tough skin. It would take many dozens of them to equal one small plum from the supermarket - hardly an energy boosting snack.
I hate to disappoint you but the Garden of Eden - chock full of luscious fruits just for the picking - doesn't exist in most of nature
I hate to disappoint you but the Garden of Eden - chock full of luscious fruits just for the picking - doesn't exist in most of nature. If you don't believe me, trade in your designer jeans for a sharp stick and a few rocks like I did, and head out to the wilderness to see for yourself. It's quite an education.
