The two pictures in "a brief history of commercial fishing" show us that fish have become less and less since the begining of 20th century. In 1900, when only a few people fished with simple sailing vessels, there were plenty of fish. As it entered into 1995 and there came an in creasing number of advanced fishing ships, fish became extremely rare.
Though it is an exaggeration to draw only one fish remaining, this really warns against the tendency for fish to become extinct. Evidently, which is caused, directly by excessive commercial fishing. If this situation goes on, we will surely have no fish to eat in the near future. It is most likely that by drawing the pictures, the artist intends not only to tellus the story of fish but also to set us thinking more about nature. First, fish, together with ali other natural resources on earth are limited.
Second, with modem science and technology, man should not fish excessively just for enormous private interests. Last but not least, we really should take active and effective measures now to counter the excessive commercial fishing for the future of fish and for our offsprings.Only on the basis of the protection can man have fish to eat permanently.
So protecting and raising fish should go be fore or simultaneously with fishing. In my opinion, above all, laws must be made: before and while fishing, commercial fishers must raise much more fish or pay high taxes and they must only be permitted to fish certain species in certain areas and seasons.
Otherwise, they must be punished: fined, vessels confiscated or put in to prison. Gradually, man will learn to raise animals especially for earning money, which will be a safe, long-lasting and prosperous cause.
As for this, our ancestors, by keeping domestic animals, did much better than we modern human beings do.
