Thank you for sharing the video. It is well explained, and well balanced. I know how edited are nature documentaries. But I like them anyway. As the video says

Thank you for sharing the video. It is well explained, and well balanced. I know how edited are nature documentaries. But I like them anyway. As the video says that makes it more a story, that makes it more interesting. The pictures with captive animals are a different thing. As chaining a wolf so people can take nice pictures is cruel. To make animals suffer to take a nicer picture without any scientific value is immoral.
