So three things need added to the formula:
1) How much space is really needed? As Lynda has pointed out, if you forego
the beef and pork and eat chicken and rabbit, 90% of your diet can come from a
very small place.
2) Most of the land that could be cultivated like this is not counted a
potential farm land at all.
3) Horticultural cultivation is vastly more efficient than machine based
agribusiness in terms of resources needed for a given amount of produce.
