What is the main cause of hunger in world?

* Poverty: Poverty is the single biggest cause of hunger in the world. When people are poor, they often don't have enough money to buy food, or they may not have access to land or other resources to grow their own food.

* Conflict: Conflict, such as war or civil unrest, can disrupt food production and distribution, making it difficult for people to get the food they need.

* Natural disasters: Natural disasters, such as floods, droughts, or earthquakes, can destroy crops and livestock, and can also disrupt food distribution networks.

* Climate change: Climate change is leading to changes in weather patterns and temperatures, which can make it difficult for farmers to grow crops. It can also lead to more extreme weather events, such as floods and droughts, which can damage crops and livestock.

* Population growth: Population growth is also a factor in hunger, as it can lead to increased demand for food, which can put a strain on food resources.

* Food waste: Food waste is a major problem, as it can account for up to 30% of all food produced. This food is often wasted by supermarkets, restaurants, and consumers.
