There is confusion about the current number of Polar Bears, and if they should be considered an endangered species at all? This video by Grainger below, shows skilled scientists at work finding proof that they are threatened indeed. There could be a reason that some believe the numbers of polar bear have gone up. It could be the rate of ice melt has driven the polar bear to wander more often into human habitat than ever before in history. The polar bear has been a hard animal to track due to the habitat they call home. However, now that there are more advanced ways of tracking, such as with aerial methods, current counts have become more accurate.

There is controversy over the fact that some believe the polar bear population has increased, while, global warming scientists believe the numbers are in a large decline. Why is that? The number counts of polar bears in history has largely been gathered by word of mouth or rather, stories of hunters and explorers. The counts didn’t come from scientific surveys as they do now. The polar bears experienced a decline from over hunting, and were then protected, their numbers increased due to those hunting limits. The species started to recover. Now, in recent history we are seeing a species starting to show stress from loosing habitat from human encroachment, as well as being affected by the obvious loss of sea ice. This loss of sea ice makes finding food harder for them. Driving them to swim greater distances, sometimes to the point of drowning. As this video by Grainger shows us, this food challenge is shown by means of less weight over all in these magnificent animals.
The Polar Bear Specialist Group (IUCN) at Copenhagen, 2009 said, it is believed that 8 of the 19 polar bear sub-populations are in decline. There are 3 species that are stable and one that is increasing and there are seven species that don’t have sufficient information to report data on. According to WWF World Wildlife Fund, the numbers are at between 20,000- 25,000. That sounds like a good number, but the fact they are loosing their habitat at an alarming rate is what is placing them at risk.

There is still time to change the course of things. We can make a difference one voice at a time. Alternative energy use is one of the biggest ways. In light of the Gulf Oil Crisis, it seems even more evident to many. Let’s collectively work for a healthier tomorrow.
