The killings and kidnappings of which you speak are largely centered in the Republic of Port au Prince, which I would argue is not really Haiti. There is much that is right about Haiti, but it is hard to find any redeeming value in Port. Why reforest? Because of erosion the soil in the countryside is becoming less productive each year. This means less food, less health, more people streaminig into Port, and less stability. Less stability leads to poverty, crime, and isolation. By all means, we need to trackle crime - but we need to go after the root causes as well. Preserving (what is left of) the environment is fundamental.
