The Week:

I’m here to tell you, downtrodden countrymen (and women), that there is a remedy for our particular affliction. It can be found in the flutter of a hummingbird’s wings, or the determined eyes of a crouching snow leopard. It’s in the gallop of a giraffe as it’s pursued across the tundra, and the heroic leap of a penguin from razor-sharp cliffs. Mix in a cinematic score by Hans Zimmer and the soothing sounds of David Attenborough’s voice, and the formula is complete. Lift your eyes to the TV screen, my weary friends. What we need now, perhaps more than ever, is a hefty dose of Planet Earth.

I don’t think you need a scientific reason. Watch it just because it’s good TV.
