The Green Coalition supports efforts to connect CUNY students with the local food economy. One way students can do that is by joining a CSA/Farm Share in their local neighborhood. A farm share is usually a subscription to the season's harvest - you pay the farmer up front and then enjoy fresh local seasonal vegetables (and sometimes fruit, eggs, meat and/or flowers) every week, approximately June to November. Joining a farm share/CSA is much cheaper than shopping at the farmers' markets around the city and helps farmers by providing capital before the growing season begins.
There are many many farm shares/csa's in the city but they tend to fill up early. This year, many will be inviting new members to join on March 1, 2009. There is a list of CSA's by borough and neighborhood here: http://www.justfood.org/csa/locations/ .
Support your local farmers and eat delicious food all spring, summer and fall (there are a few winter CSA's available in the city, too).
