These numbers represent relative numbers of whales caught by all countries throughout the last 150 years, worldwide. They are taken from several sources, including official surveys of whale populations and logbooks and catch numbers from whaling vessels. It is difficult when studying whales to be certain of numbers because ocean conditions make it impossible to be 100% accurate. Construct a graph with the information above. Numbers of whales should be placed on the X-axis (horizontal) and Year on the Y-axis (vertical). After completing the graph, answer these questions: 1. How do the three species differ in their plotted lines? 2. Which species, based on the data above, seems to be in the most danger of extinction? 3. Which twenty year period was most damaging for Right and Humpback whales?
