Hunting is not the biggest threat to polar bears. Scientific studies point to a much larger issue as to why polar bears are becoming endangered. The true reason is that global warming is not only affecting people, but the whole environment. The home of the polar bear is Antarctica, in the South Pole. The lowest recorded temperature was once -136 F, but is suddenly increasing and becoming warmer. Recent temperatures in the home of the polar bear show that they are around -20 fahrenheit-on its coldest days-and that's saying something (Gorman 2014). To understand how polar bears are being affected by global warming, there are three things to learn about first: how they currently live, how people are affecting them and why it is becoming increasingly
