Similarly, the shark-diving industry has brought in an estimated $110 million annually to Thailand, $22 million to the Canary Islands, and a massive $800 million to the Bahamas over the last 20 years. It is not difficult to see why allowing fisherman to decimate these countries’ shark populations would be counter-productive.
同样，鲨鱼潜水业过去20年间带给泰国约合1.1亿美元，加那利群岛约合2200万美元、巴哈马群岛高达8亿美元的年收入。因此不难看出坐视渔民消灭上述国家的鲨鱼种群为什么起到适得其反的效果。
