BROOKLYN - New York City council members are holding a hearing today to examine the fight against hunger after an advocacy group released an alarming study. According to the United Way, nearly 40 percent of all New Yorkers struggle to afford groceries. In addition, City Harvest organizers revealed a 25-percent increase in demand for emergency food assistance since 2008. However, the city's Coalition Against Hunger says more than half of the area's food agencies fail to meet the demand, and have been forced to reduce portion sizes and reduce operation hours.
