PLOT
National Geographic Magazine photographer Joel Sartore shoots in some of the most exotic locales on earth, often in wretched conditions for weeks on end, and always under pressure to produce worthy pictures. A husband and father of three, he often wonders if it's the best job in the world or the worst. ""At Close Range"" reminds us of where we fit in the cosmos, and what we owe to the next generation of all the earth's inhabitants.
