Sir David Attenborough narrates this BBC time lapse clip on YouTube. If you do not have the BBC Planet Earth series, and you are concerned with all things related to nature and our planet, I recommend that you get it if you can. The quality and flow are better than with YouTube.
Watching the polar bears as they struggle with a disappearing habitat was heartbreaking for me. (In order to see that, you will need to watch the next one-minute clip in the series, called Polar Bears on Thin Ice)
If you are not in a nature mood today, but you enjoy creativity, take a look at this 4 minute short film, called Table 7. A couple in a restaurant is unaware that they are being monitored and recorded. But why are they being recorded? What will happen to them?
