Here is an excerpt from an article written by Wendell Berry for Edible Brooklyn Magazine.
What can "City Folk" do to support local farmers and the food security movement?
1. Participate in food production to the extent that you can. If
you have a yard or even just a porch box or a pot in a sunny win-
dow, grow something to eat in it. Make a little compost of your
kitchen scraps and use it for fertilizer. Only by growing some food
for yourself can you become acquainted with the beautiful energy
cycle that revolves from soil to seed to flower to fruit to food to
offal to decay, and around again. You will be fully responsible for

6. Learn what is involved in the best farming and gardening.
7. Learn as much as you can, by direct observation and experi-
