None are killed on screen, but dead polar bears that have been shot by a drone are seen lying bloody. Dead animals are seen to be sold as food. Other animals are seen in a train with other passengers, some in cages and some not. Nothing happens to them.
Polar bears that have been shot by drones (that shoot anything that moves, apparently to prevent border crossing) are shown. The main character purchases a dead animal that he butchers and cooks at the beginning of the movie, a dead animal is seen hanging in an open air market for sale.
Not quite sure. There was a large group of people trying to get passage on a submarine, and only a few made it. Some fell in the icu water, others were left behind to maybe die, and some were shot. A father and young boy were left behind, and maybe died.
