I still eat a variety of fruits that sometimes come from distant lands. Eating local is easier to do in summer, but not so easy in winter. How much energy does it take to can? How much space. I live in a small urban space with little place to store things.
Some folks would move to a rural area so they can have their own apple tree. Then they can end up commuting farther than the average city dweller thus having more, rather than less of a carbon footprint.
How much energy does it take to ship small pieces of fruit from afar? Probably not as much as it would take if everyone lived much farther from their work and errands so each of them could try to have a garden.
"Drive till you qualify." Qualify for a mortgage that is. A mantra of sprawl.
