This picture shows a drastic change in the worlds commercial fishing. The two parts display totally different scenes in 1900 and 1995. In 1900, there were a large number of fish while only one boat was fishing on the ocean. But in 1995 fishing boats increased sharply while only one fish was left. The fish supplies have almost been exhausted by overfishing.
Judging from the picture, we can see that within about 100 years, humans have stripped the sea of her generous offerings. If we dont put an end to the trend, then the fish in the ocean could become extinct species in the foreseeable future.
Therefore, it is high time we took effective measures to solve this problem. First, we must bring world population under a reasonable control, as overfishing is largely due to the need to fill the additional mouths. Second, every year in the fishs mating season, a "grace period" should be enforced during which the fish are allowed to reproduce themselves. Third, strict laws should be implemented. Last but not least, we should enhance the awareness of the public that the ocean resources are very vital to us. Only when these above mentioned measures are put into practice can we save the fish from disappearing completely.
