In the finale, wonders created by life itself are examined. Included: boys in the Amazon face fierce animals in a rite of passage; and a Bangladeshi man and his son face killer bees and man-eating tigers in a quest for honey.
Part 1 of 3. A look at life amidst the world's extraordinary wonders starts on Mount Everest, where the Kumba Icefall presents a danger to sherpas. Also: conservationists at the Grand Canyon try to help a condor chick survive; and farmers battle elephants on the slopes of Mount Kilimanjaro.
