Since the shuttering of the stunning Tempelhof city airport of Berlin in 2008, a rather sad winding down of a historic place--built on lands owned originally by the Knights Templar and witnessed the Airlift of Berlin during the Cold War when the Western exclave was blockaded by the Soviets, people have been trying to come up with good ideas for use of this massive space.
Certainly the variety is available but it isn't grown overseas, and while it may come from the fields of Spain sometimes, a lot, greens less hearty and less suited to Germanic climate, is grown here in hothouses and with a modicum of coaxing in nicer weather. With food prices rising out of proportion, there is a lot of talk of sustainability and feeding an exploding population and doing so more efficiently through vegetarianism (yay!)--all of which are certainly pressing and deserving of attention and serious thought, but maybe realigning one's attitude towards food begins with growing one's and bringing it to market.
