At this time of year it's important to pause, take stock, and cry like a little baby when you watch this clip narrated by Sir David Attenborough.

In a brilliant bit of promo, the BBC folks got Sir David to speak the words of Louis Armstrong's 1968 classic, 'What a Wonderful World', over video of the planet being frikking awesome.

We could go on about it forever, but it's better if you just watch the thing, left.
