As unfortunate as this is, afaik, polar bears are one of the most aggressive animals around, intent on eating pretty much anything that moves. I don’t doubt that it did pose a threat.
Most murders are committed by people. I say we reduce the number of people, perhaps through allowing them to destroy the environment so that they cannot survive. This will make the world safer in the long run, and it will also teach humans that their actions have consequences.
As a side effect, polar bears will also die, so everyone will be happy (and dead)!
Or, you know, just the ones that are actively posing a threat. Like in all such animal situations.
So what about humans posing a threat to them? If it’s so rare to have them show up in Iceland, what drove a polar bear to do this? From what I understand, with less ice at the poles it has made it harder for polar bears to hunt seals, leaving many of them starving. As we head towards winter, polar bears have to put on fat stores to survive and feed newborn cubs. It’s really a shame that so many people talk about “animals” as if we aren’t animals too. By your logic, there would be nothing wrong with polar bears rolling into town and eating the species threatening their survival.
Since my comment was removed for trolling (I wasn’t trolling, it was just sarcasm), I will rephrase it. If we accept the premises that any polar bear that is a threat should be killed and every polar bear is inherently a threat, then the conclusion is that every polar bear should be killed. I reject the first premise and conclusion.
