While marveling at the beauty of ice and snow and the music completely integrated with the documentary, I saw a lot of very worrying pictures. The compressed living space of the walrus, the scene of hesitating to go to an unfamiliar cliff and stumbled and rolled down to the beach is very shocking. The most fundamental reason for all this is global warming, and what is causing the current situation is the uncontrolled development of industrial society. Perhaps because we are too far away from the Arctic, Antarctic and the habitats of real wild animals in our real life, our perception of natural world documentaries is no less than that of science fiction films. Because it is difficult for humans to empathize with places they have not personally set foot in, we are too unfamiliar with the real animal world, but our influence on them is too profound. Humans claim to be the most intelligent creatures on the planet, but now they are just selfish misers and cowards who don't care about the life and death of other creatures.
