The area off the coast is not a prime agricultural area or offshore oil drilling location, but does experience a very high fishing pressure. The graph below indicates when industrialized trawling began (1960) and when the Canadian government imposed the controversial moratorium in 1992. Where appropriate, use the graph to answer the following questions.Ind. trawlingExplain with supporting detail two specific reasons why industrial trawling would produce the change shown in the graph for the 5 year period after 1960. Identify the 10 year period during which the greatest decline in the fish harvest took place. For that 10 year period, calculate the average rate of decline in the fish harvest, in thousands of tons (metric tons) per year. Clearly show how you determined your answer. Compare and contrast the environmental effects of the commercial fishing practices of trawling versus the use of drift nets. Of all the marine pollution effects currently being experienced by the world’s oceans, which two specific pollutants would marine organisms off the coast of Grand Banks most likely experience? Support your answers with full explanations. ................
