A two-part visit to "Antarctica: The End of the Earth." Part 1 examines how the continent has been shaped by its prevailing wind, "The Katabatic." Narrator Joseph Campanella describes it as "the Antarctic's overlord---a ruler so merciless that nothing escapes its reach." Animals that must cope with the 200-mph winds include seals (Antarctica's only full-time residents, one of which is seen giving birth) and snow petrels, sea birds that "commute" 500 miles to inland nests. Also: scientists find disturbing evidence of global warming.
