This past summer there seemed to be a lot of attention paid in the media to urban beekeeping and it was fascinating to learn that bees prosper in high-density urban environments. Very inspiring, and a good example of how the urban world can be a (food) productive place.

If that's the model we're looking at for food production in cities, that'd be wonderful. More food production in cities would be great, so long as we steer clear of the utopian garden cities et. al. that led us to the current sub- and ex-urban blight that fills so much of the modern landscape.
