Changing Planet

In the final episode of the series, cameras in space show that the surface of the Earth is changing at a rapid pace as cities grow, forests disappear and glaciers melt. In ever growing grey of cities one man is feeding thousands of parakeets, while in Sumatra, a female orangutan and her daughter face life in a forest under threat. Elsewhere in Tanzania, local people use satellites to re-plant a forest, securing the future for a family of chimpanzees. Last in the series.
