The following graph shows the earth’s total fishprint and biocapacity between 1950 and 2000. Study it and answer the following questions: Based on the graph, In what year did the global fishprint begin to exceed the biological capacity of the world’s oceans? By how much did the global fishprint exceed the biological capacity of the world’s oceans in 2000? Assume a country harvests 18 million metric tons of fish annually from an ocean area with an average productivity of 1.3 metric tons per hectare and a weighting factor of 2.68. What is the annual fishprint of that country? If biologists determine that this country’s sustained yield of fish is 17 million metric tons per year, What is the country’s sustainable biological capacity? Is the county’s annual fishing harvest sustainable? To what extent, as a percentage, is the country undershooting or overshooting its biological capacity?

If the human species were to suffer a population crash, what are three species that might move in to occupy part of our ecological niche? Hint: State at least two pieces of evidence/reasoning from our discussions and the chapters we have read this semester to back up your claims.
