This document discusses famines throughout history from ancient civilizations like Egypt, Mesopotamia, and the Indus Valley to more recent events. It describes how climate change events like the 4.2 kiloyear drought contributed to the decline of these early civilizations by reducing food production. It also examines how conflicts have exacerbated famines by destroying infrastructure and using starvation as a weapon of war. Currently, the Food and Agriculture Organization aims to achieve food security and end hunger for all people, but ongoing issues like poverty, inequality, and conflict continue to challenge this goal.
