Planet Earth is a worthy documentary series that looks not just at the animals and plants in remote areas, but at the ever-changing ecosystems that look prone to collapse in the near future. This is the sort of programme that the BBC excels at and makes better than anyone else.
The camera-work is fantastic and the sections at the end of each programme where they look at how certain parts were filmed is interesting as you see the dedication of the crew who go out to these desolate spots for months to film sections that will last only a couple of minutes on screen. Much of the wildlife has barely been filmed and some such as the wonderfully agile Wild Amur leopard have probably only been seen by very few living people in the flesh.
It is narrated by David Attenborough who has the perfect voice for wildlife documentaries and his presence is almost a guarantee of quality in itself. His record speaks for itself.
Some of the sequences shown are very brave, most notably the struggles of the polar bear to find food on the ever-decreasing Arctic ice. Too many nature documentaries succumb to "niceness" and show only cute animals looking sweet. To understand how Man is changing the planet it is crucial to show how wasting energy may be affecting wildlife in distant lands (or seas). Sadly it is also important as it seems all too likely that much of the footage will become museum property in the near future, showing subsequent generations the marvellous diversity of life Earth used to enjoy.
Overall it has some good educational value as it can be enjoyed both by young children and was recommended by my tutors during a conservation module of my degree.
