For the second part of this assignment, you will apply the readings to two cases in which conservation of habitat applies to carrying capacity and economics. Choose one of these large predators to investigate: One of the large cats (i.e., lions, cougars, panthers, etc.) or polar bears.What size of land/water is required to support this animal?What pressures threaten this organism’s habitat?What role do international trade and political regulation play in protecting this organism?
