Apparently, it is shown in the picture that one boat caught numbers of fishes in 1900 while in 1995 the phenomenon was on the contary,which implies that over-fishing is becoming an issue.
The brief history of world commercial fishing indicates the result of over-fishing, which caused many problems of environment and economy. In the first place, sharp cut-off of marine organism would result in broken ecological balance, including an excess of aquatic plant followed with water polluted. In the second place, fishery without limits does not fit for sustainable development.
Thus, policies and regulations should be taken to impose restrictions on fishing. At the same time, making the commercial fishermen realise the harm of unplaned fish-catching is another point government should emphasis on. Only through these ways can human beings benefit from the nature for a long time.
