This heartbreaking documentary puts a face on the sad statistics of global warming--and though it's not a human face it's the perhaps even more effective face of an adorable polar bear cub Nanu along with her mother her brother and her natural enemy the equally heart-melting Seela the walrus. With breathtaking footage of life on the arctic tundra the directors spin a highly emotional tale of the melting ice caps and the effect of their disappearance on every species in the ecosystem.Since the film is essentially aimed at children the cuteness factor is off the charts aided by the slightly grating use of sound effects a slangy voiceover by Queen Latifah and a kid-friendly pop/folk soundtrack. And as in a National Geographic special viewers learn some interesting and neutral facts about polar bears walruses narwhals foxes and other northern creatures. The narrative however returns repeatedly to the grim conditions that are killing off our planet's wildlife one family at a time. The directors take pains to create a hopeful ending with a sweet pair of life-goes-on epilogues and a closing credit sequence featuring conservation tips but the message of the film is sobering and hits its mark with kids and adults alike.

National Geographic provides a whole new perspective on the extraordinary processes involved in human life with this primarily internal look at the human life cycle from conception through old age. Thanks to amazing technological advances like camera pills and high-definition endoscopes, physicians and scientists can now obtain actual camera footage and images of body processes as well as create elaborate computer simulations to aid in the research and understanding of how the human body works. This 95-minute exploration of the human body and its processes follows human life from fetal development through the amazing changes demanded of virtually every organ in the hours after birth, childhood, adolescence, adulthood, and old age. It explores the senses and how they work, brain development, digestion, blood circulation, cell division, the hardening and replenishing of bone, puberty, sexuality, childbirth, changes inherent in the aging process, the virtual shutting down of the body at death, and much more. The fascinating camera footage includes everything from the digestive process of food from the mouth through the esophagus, stomach, small intestines, large intestines, and then to excretion; to blood flow through the heart, veins, and capillaries; and the accumulation of fat in the abdomen and intestines.
