Answer:
D. Mangrove forests tend to increase the commercial fish populations in coastal fishing grounds
Explanation:
From the scenario, we can see that
''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.''
From the above extract of the scenario it is clear that loss of mangrove forests reduces fish population. If the foregoing is true, then reduction in fish population implies reduction in the revenue of the Gocha Fishing Cooperative. Secondly the loss of mangrove forests has not only led to loss of revenue due to less fish but also increase in cost by having to fund dredging
Therefore, based on the fact that loss of mangrove leads to loss of fish and by extension revenue, planting more trees will lead to more fish and more revenue, apart from the fact that the cost of dredging will not have to be incurred leading to greater revenue.
