[Greenbuilding] Growing food by electeric light - urban sustainability?

[Gennaro]

I'd like to add there its more to food than calories and nutrition.
Community, spirituality, connectedness, ritual, sacredness, and meaning are
a few of the things. if food were simply nutrition and calories we would
keep our food in a pill in the bathroom medicine cabinet.
