As is shown on this two pictures: In 1900, there are a marjority of fishes in the waters while only one ship on thewaters. And yet, in 1995, there are only one fish while a host of ships on the waters.
As is shown in these two pictures, in 1900 there were plenty of fishes but only one fishboat on the waters, while in 1995 there was only one fish but fleets of fishboats on the same waters.
Obviously, the drawer of the pictures want to show us that the number of fishes has been decreasing rapidly because of the commercial fishing all over the world. Perhaps the drawer want to remind us the importance of protecting the fishing craft. Since the overdue activities of hunting fishes may cause the disappearance of the fishing. Fishermen shouldnt neglect the sustainable development in order to obtain the short-term benefit. We disapprove of the complete ban on hunting fishes. But we dont agree the severe activities of hunting which do more harm than good.
Obviously, the drawer of the picture wants to show us that the number of fishes has been decreasing rapidly because of the conmmercial fishing all over the world. Perhaps the drawer is remiding us of the importance of protecting fishing industry since excessive catching may lead to the disappearance of the fishing industry. Fishermen should keep in mind the sustanable development rather than gain the short-term benefits. We disapprove ofa complete ban on catching fish. We dont agree, either, on the excessinve catching, which would do more harm than good.
Thus, the department involved should tell the fishermen of the importance that keep an mild hunting activity. In addition, they can make some regulations to sTOP the fishermen from hunting in slack season.
Thus, the authority should educate fishermen on the importance of rational fish-catching. In addition, they should make regulations to sTOP fishermen from catcing in fishing-off season.
