Loss of the Gocha mangrove forests has caused coastal erosion, reducing fish populations and requiring the Gocha Fishing Cooperative (GFC) to partially fund dredging and new shore facilities. However, as part of its subsidiary businesses, the GFC has now invested in a program to replant significant parts of the coast with mangrove trees. Given income from a controlled harvest of wood with continuing replanting, the mangrove regeneration effort makes it more likely that the cooperative will increase its net income. Which of the following, if true, would most strengthen the argument that mangrove replanting will increase the Gocha cooperative's net income? ['A controlled harvesting of mangrove wood by the GFC would have little effect on coastal erosion.', 'The GFC derives 10 percent of its revenue from salt-production facilities in an area previously cleared of mangroves.', 'Mangrove forests tend to increase the commercial fish populations in coastal fishing grounds.', 'The GFC will be able to hire local workers to assist with the mangrove replanting.']
