Another way to help is avoid buying stuff that happens to be made in Haiti by semi-slave haitians in infrahuman conditions so you can save some cents, you can help Haiti not only when they have an earthquake!
If you decide not to trade with me because you think I worked too hard or had to get up too early to get that milk, neither of us is better off. Even worse is when you decide not to trade with me because someone else told you not to, for my own good.
