The video shows a shadow of a polar bear, barely able to walk while dragging its back legs, possibly due to muscle atrophy. Searching for food in the nearby trashscan, the bear found nothing and suddenly it collapsed down for a final breath. You can watch the video below.It is obvious to anyone by now that these are the consequences of climate change and human activity. It is estimated that polar bears could be extinct by 2050, not to mention the countless other species that already went extinct or are on the verge of it. Unless we drastically change our behavior as a species, we are going to lose a big chunk of what makes this planet beautiful.
