at some point in the reblog chain somebody removed the caption, which read this: A young polar bear cub filmed over the first 83 days of her life, via Columbus Zoo and Aquarium. from a quick Google, the Columbus Zoo is an active part of Polar Bear conservation, this cub’s name is Kulu!
this is a very sweet video from a good source! always support accredited zoos. ignore the guy in the notes talking about zoos being evil prisons or whatever, they do amazing work for conservation and without them species like the California Condor would be long extinct.
