Four things contribute to most of the world's hunger:
- Poverty: Poor people do not have the resources—whether land, tools or money—needed to grow or buy food on a consistent basis.
- Armed Conflict: War disrupts agricultural production, and governments often spend more on arms than on social programs.
- Environmental Overload: Over-consumption by wealthy nations and rapid population growth in poor nations strain natural resources and make it harder for poor people to feed themselves.
- Discrimination: Lack of access to education, credit and employment—a recipe for hunger—is often the result of racial, gender or ethnic discrimination.
