FamilyFarmed is a natural ally for star singer-songwriter Jack Johnson, an environmentalist and supporter of sustainable food. We also are benefitting from the financial generosity of his All At Once Network, which matches donations to dozens of non-profit organizations. But FamilyFarmed learned that Jack Johnson is generous with something extra — his time — when we attended his June 2 concert at Chicago’s Huntington Bank Pavilion to participate in the “Village Green” with other local non-profits.
