The square fields of Central America look very neat and efficient as the aircraft flies by, however a more important issue can be drawn from the 'neatness' of this situation. Many million acres are cleared of all vegetation and fenced into huge paddock sizes to produce an often monoculture of crops. The implications? More pests and disease in fields (greater reliance on chemicals to control these issues) and greater losses for the farm if that specific crop fails. We need to start considering what nature intended. A multitude of plant species and habitats for natural predators, biodiversity and better general farm health.
