Towards Dignity: Understanding The Relationship Between Food Banks & The Right To Food In The United States, Marguerite Leek
Theses - ALL
In the United States, there is no legal right to food. The right to food is more than food security, it encompasses dignity, access, choice, financial security, and more. Rather than addressing food insecurity through a human rights-based approach, the US relies on a complex system of emergency food providers, including food banks. Food banks most often take a charity approach to providing individuals with food, failing to meaningfully recognize or address the structural causes of hunger and poverty. In recent years there have been increased efforts made by civil society to move conversation and state level policy in the …
