With 48 million people in a country that's slightly larger than Indiana, South Korea has
to use every possible square meter of land to feed its populace. Laws make it difficult
for developers to turn farmland into housing developments, and make it easy to use
public land for basic food processing. At harvest time, grains, vegetables, and herbs
are set out to dry on guardrails and sidewalks. One wonders, though, how particulates and gases from vehicle exhaust affect the foods when they're dried just a few meters from the highway.
