A small group of boys are seen looking for fish that may have fallen from fishings boats that enter and leave port. Senegal is a dramatic example of a trend playing out across the world, in which 90 percent of fisheries are fully fished or facing collapse, according to the Food and Agriculture Organization of the United Nations. The crisis has been exacerbated by European and Asian fleets prowling the seas off West Africa. What these boys find will either be sold or taken home for a family meal.
