A food bank is a non-profit organization that collects and distributes donated food to people in need. It serves as an emergency resource for individuals or families who are struggling financially and cannot afford enough food to meet their nutritional needs. Food banks often work with other organizations, such as shelters and community centers, to provide meals and groceries to those who are experiencing hunger. The goal of a food bank is to help alleviate the immediate need for food while also addressing the root causes of poverty and inequality in society.
