Troubles for the polar bear
#1
http://www.bbc.com/news/science-environment-42909866

This article discusses that effect that climate change has on polar bears, first hand through a " bear's-eye view". By attaching GPS trackers and metabolic tracers on the polar bear's scientists are able to monitor their expenditure's of energy and see any hindrances as they appear. With these new technologies, scientists are capable of finding new solutions to the growing impediments had by many animals affected by climate change.The displacement of polar bears as the Arctic sea ice dwindles has drastic effects on their diets, traveling further to hunt food expends even more energy which ends up being counterproductive. However polar bears can adapt to traveling long distances and may have the capacity to adapt to ongoing climate change, but due to their large dependence on the Arctic ice, it seems unlikely. If the trend's of ice loss and rising temperatures continue as is, the polar bears may need to find new sources of food or alternate their hunting methods. Having doubted climate change it seems more and more difficult to argue that it is not a fact. Thought all these challenges polar bears are facing it seems the future for our neighbors up north is not looking bright.

I agree that the situation for the polar bears continually worsens. Luckily they are very hardy animals and have, as you said, shown promise in their ability to adapt. Climate change is an issue that will continue to persist, however, and I worry that it is a lot more than just polar bears that will suffer from it. To me, the technology behind the GPS and metabolic trackers is incredibly interesting, because, if you looked at the picture, they were small enough to comfortably fit around the bear's neck and beneath their noses,while also being waterproof, resistant to the cold, and sturdy enough and with a big enough battery to endure everything that a bear does for three years. It would be really interesting to look at the technology behind the production of these collars and see how they could be applied commercially, such as for phones that can withstand any type of weather. People would no longer have to worry about losing their phone's battery lives by leaving them out in the cold.

Polar bears need to be genetically modified to be able to use guns so they can fend for themselves

You mentioned phones dying due to being left out in the cold but the truth of the matter is that this issue only affects Iphones. This issue has been resolved my the majority of all android and all Samsung phones that have been released in the past 3 or 4 years. The point of this is that Samsung is clearly the better option when looking for a phone. Especially living in a city like Edmonton with its callous weather. When someone hears Samsung they think of exploding batteries which is caused by the lithium-ion batteries being pushed further then they should be by the manufacturer trying to get every bit of battery life out of the phone. But that is the only major flaw Samsung has had and its already been resolved. Meanwhile Iphones are still breaking at the same rate they were 5 years ago and have the same bugs. Also an IPhone can die in your hand while being out in the cold while a Samsung can be left in a cold car for a while without dying.
