According to the United Nations World Food Programme (UNFAO), over 800 million people in the world suffer from malnutrition. 

While media attention often focuses on extreme cases of hunger, most hungry people suffer from daily malnutrition — meaning they consume fewer calories than a healthy life requires.

Persistent malnutrition impairs the ability to study or work, and especially in children, affects academic progress and mental and physical development. It also weakens the immune system, increasing susceptibility to disease.

Despite enough food being produced to feed the entire world population, The main problem is not the lack of food, but the uneven distribution. The main factors that cause hunger include:

• Poverty
• Climate change
• Conflicts and wars
• Poor agricultural practices
