I suppose the best thing to do, on a personal level, for world hunger is to become a productive member of society. Create wealth, so there's more to go around, rather than just shuffling around what already exists.
Then give a share of what you make to the AG Disaster Relief Fund or the Red Cross, or something like that. Those who have enough giving to those who don't is one of the most important ways that wealth moves through the world economy, but it's generally considered best to do so through an organization with a reputation for being good at it.
It's like hiring an expert to give your money away for you, so you don't get scammed, or otherwise cause more harm than good.
