A dead seal and a walrus. There is a long scene at the beginning showing an Inuit hunter killing and butchering a seal, and they eat the raw meat. There's a walrus at the end that they hunted as well.
Kind of? It ends on a hopeful note but the documentary on the whole doesn't show them making a lot of progress and they still haven't reached a concrete solution by the end.
It shows the whole process of slaughtering and taking apart a whole seal, which involves a lot of blood and gore, and then everyone lays out the meat and eats it raw. A photograph shows children with blood on their faces from eating the raw meat. None of it is meant to be horrifying or scary, but it could definitely be hard to watch if you're squeamish.
