If living totally off the grid food-wise...and looking at the amount of fruits and veggies the average adult needs to survive during a SHTF society... How much land is needed to grow that amount of vegitation per person? And what plants are the most nutricious and easiest to grow climate/care-wise? Canning-wise...how many jars would be needed? Again this is per person. I'm not sure if there's an equation for it or if someone else has already figured that out...so I figured I'd ask. -Emt1581 Wanna kill these ads? We can help!
