The malnutrition that affects millions of people in tropical countries is inextricably linked to problems in food production and distribution.

New means of sustainably producing food need to be introduced. Fish farming has had a largely failed history in Haiti and Africa because of dependence on expensive manufactured feed that usually must be imported. MORE>>>
