Yet in another place in the world, e.g., in many villages in Rwanda, a small plate of boiled potatoes is a big meal, when they can get it.
Our world as a whole does not necessarily lack food. Nobody really needs to be hungry. But some have too much while others have too little. We may not be the cause of the problem but we all can be part of the solution. There is no silver bullet for the problem but it is not impossible if we are willing.
Service-Learning is one way to address the problem.
