My garden is pretty small, but I have 13 fruit trees and more deer than I can eat. I don’t anticipate starving either.
What I do anticipate is a lot of folks complaining about rising food costs.
If this gets more people to raise gardens, it may not be an entirely bad thing. Most Americans eat diets that are less healthy than they ought to be—not nearly enough green vegetables, too much refined sugar and starch.
When I get home from work today, I’ll munch on some fresh greens, and then plant another row of cantaloupes. :<)
I “farm” about 2100 sq. ft., but, if I didn’t starve, I would get very tired of the diet if I had to survive on what I grow.
Maybe a few deer would help, but they all would have to be made into jerky for me to be able to eat them. I have a good fence, so deer do not invade my garden. I could, I suppose, live on rabbits, possums, and an occasional skunk? for meat. Could also harvest a lot of birds. Fried grasshoppers and earthworms? Pass.
Most of my veggies are perishable, so we only eat most of them in season (strawberries, asparagus, melons, lettuce, spinach, beets, tomatoes, peppers, corn, cucumbers, beans, carrots, onions, radishes), though I do freeze corn and peppers, can beans, asparagus and tomatoes, and store potatoes and onions.
I would probably be ahead to sell my produce fresh, and use the money to go to the grocery store for most of my food. Might also be ahead to quit gardening and get a job, but then I would have more grass to mow and water, and that sounds like less fun.
