the bbc’s planet earth is by far the most compelling, visually stunning, and immense natural history series ever. It's focus spans from abnormal carnivor behavior (due to increasing habitat change), vast migration, importance of bio diversity, layering life support systems (and how they are all connected), rare and endangered species, never before seen environments, and much, much more. narrated by the legendary david attenburough, the show constantly leaves your jaw wide open. the last disc of the series is very important, featuring interviews from natural history film makers, scientists, and activists. there is a world of insight on the last disc, a compelling end to a fantastic series. a MUST SEE. rent it or buy it, either way, see this series!
