Purpose:  In my population class, we are finding birth rates in different countries. I examined polar bear birth rates in Antarctica. For example, in my class we looked at an equation Na=NsE^(kt). [Na is defined as the population after.  Ns is defined as the starting population. kt is defined as the birth rate.] So we try to base our research on that equation. In my poster, I talk about why the polar bear population is going decreasing. I also talk about global warming and how it is effecting Antarctica.
