Unnatural Histories was a series with a message, and in the case of one of the episodes it even seemed to have some subliminal messaging going on (and perhaps the other two and we just didn't spot it). The basic premise was that the series was looking at three great "wildernesses" which have been made national parks and investigating whether or not it's really true that these are the last great spaces untouched by the hand of man.
Pocahontas only lived for around 22 years, but her short life became an integral part of America's national mythology. A lot of the things we "all know" about her are wrong, or misleading. Even the name we know her by wasn't her real name - more of a nickname, meaning "naughty child" or something of that sort.
