CARE also provides food for about 30 million people each year, most of them are children. It gives special help when there is a flood, an earthquake, a drought or a war.

OXFARM: In the 1960s, it started working on long-term development in many countries. It wanted to attack the causes of hunger, poverty and diseases. It wanted to prevent the problems instead of trying to solve them. However, it continues to provide food to the hungry, the sick and the homeless.
