I can not think of a better example of a shining hope for our collective sustainable future than the Hayes Valley Farm in San Francisco. On the site of what was once an old freeway on-ramp, now exists a thriving organic community farm. Hundreds of volunteers have worked diligently to transform a blighted section of the city into a beautiful public space, that is also helping to strengthen the local food system and educate the populace.
Some friends and I visited the Hayes Valley Farm a few Sundays ago; it was a really fun and inspiring experience. Zoey Kroll, of the Hayes Valley Farm Biodiversity Research Team (and a regular farm volunteer), gave us a tour of the relatively new urban green space, explaining lots about what was going on that day—from cardboard sheet mulching and organic composting, to distributing free food gleaned from local farmers markets and drawing beautiful garden visions.
