Rising Polar Bear Populations and Data

Scientists in the article I discovered (http://newsbusters.org/node/12694) say that the polar bear population in Canada's eastern Arctic has grown 150% in the last two decades, going from 850 in the 1980's to 2,100 today. This data can be represented graphically and used to predict future polar bear populations, which will be affected primarily by hunting but should continue to rise. The population, when graphed, would have a (probably weak) positive trend and would serve as a perfect example of Friday's lesson.
