Sometimes you have to leave this world to get a good look at yourself. That's the lesson of "Earth From Space" (9 p.m., PBS), a "NOVA" special. During the last five-plusdecades, satellite
imagery has revolutionized our view of the planet. "Earth From Space" offers remarkable animation that makes use of more than 125,000 images taken from space.
The perspectives offered show how desert winds from the Sahara send dust across the Atlantic and help fertilize the Amazon, and how water from the Arctic region creates the ocean currents that affect climate the world over. From tiny plankton to the birth of vast storm systems, "Earth From Space" offers a gorgeous lesson about the interconnected nature of life.
---For something less cosmic, but just as beautiful and often moving, "Nature" (8 p.m., PBS) presents "Cold Warri ors: Wolves and Buffalo." Wildlife filmmaker Jeff Turner spent several seasons documenting both species in Wood Buffalo National Park. Straddling the border of Alberta and the Northwest Territories, Wood Buffalo is five times the size of Yellowstone National Park and was created in 1922 specific-
ally to protect the free-roaming buffalo herds that were hunted to near extinction in the 19th century.
Those who always wanted to see buffalo in the wild should not miss this. It's hard to describe just how big they are -- or how powerful. Buffalo can weigh up to 2 tons, yet gallop for hours at a time. And that's a good thing, because wolves, the "co-stars" of this production, are just as hardy and much more cunning. That helps when you're chasing something 10 times your size.
---Speaking of remote splendor, the Philippine island of Caramoan is the setting for the latest incarnation of "Survivor: Fans vs. Favorites" (8 p.m., CBS).

I'm forming the KudKareLess Tribe for the millions who've grown bored with this.
