The record of natural history is full of wars between the exotic species of this earth and our planet's most voracious -- -- -- us humans. In a tragic number these cases our dominion over other species is meant their doom. But in a remote corner of Africa where the lines of both humans and animals are at stake each may be able. To save the other here's my co anchor. The -- It's this is. It's a shot guys like Bob pool -- for the kind of image it evokes the very name National Geographic. But few will ever fully appreciate the series of minor miracles this moment represents. First we have to find Bob. Deep in Mozambique. By trusting bush pilot who frankly looks like he should be behind us. The video game older you I'm talking ought to be exporting oil of the -- what we're gonna we're. President.
