Of course you can, I know people being almost self sustainable right now on very little land. It is hard, frugal but highly rewarding and we have evolved to do it since very recently.

Energy and heating is a bit more complicated. We obviously cannot burn wood or coal like we use to because this is actually very damaging to the planet. So this is where technology has to play a bigger role.

Farming might feel rewarding while watching someone else do the hard work. I watched and had to help my grandparents do it and went through my own decade of "farming" and it never gets easier and you only get older.

Hence why traditionally farmers either had large families, hired outside workers, or most often did both.

Please run the numbers for UK farmland divided by UK population.
