In the midst of extremely fast-paced lives, many Koreans are using every spare inch of space to garden. And not with tons of compost or fertilizer or anything much. Somehow, people are successfully growing amazing gardens in what seems to be post-construction soil, with bits of cement, rocks and sand.
What's cool is that this apparently isn't official "public" land; people just see some unused space, particularly if there's a nearby stream, and start planting until they're forced off. Usually they're not. There are 1-feet wide strips of land going up a hill that are used for growing peppers, little bits of ground on a bridge over a stream-- it's all being used.
And while highways might not be the best places for some crops, I really love the idea of using public space to grow food-- perhaps even taking it a step further, to growing "publicly available" food in public space. I'll write a post later about how frazzled and difficult life in Korea seemed to be (and I don't mean that in a paternalistic poor-poor people way), but growing food seemed to be a glimpse of the life people were longing for, even as work hours are long and being "middle class" is increasingly stressful.
Recycling in Korea is pretty amazing-- this was the trash dropoff for an apartment block of 80 families.
