Aloha Jane, check out kahumana farm I'm Waianae, they do some work for homeless families. Kahumana.org There is also a farm starting up in Waimanalo to help women being released from Oahu women's prison. Another great way to use a farm for social justice. http://www.staradvertiser.com/2016/12/09/business/farm-planned-for-community-and-ex-inmates-in-waimanalo/
