Birds perch on a cactus as a gray fox warily stands below in Chile's Atacama Desert. Rain rarely falls on the Atacama's coastline, but dense fog known as camanchaca is abundant. The fog nourishes plant communities from cactuses to ferns.

Mother Camel and Baby, Sahara, Chad, 1999
Photograph by George Steinmetz
A young dromedary camel peeks underneath its mother as she casually drinks in the Guelta Archeï, a steep canyon in the Chadian Sahara. But camels beware. These isolated waters hold a zoological surprise: Algae, fertilized by camel droppings, are eaten by fish that are preyed upon by a group of crocodiles.

Cranes, Bosque del Apache National Wildlife Refuge, 1995
Photograph by Joel Sartore
Silhouetted against the sun, sandhill cranes glide over the wetlands of Bosque del Apache National Wildlife Refuge in New Mexico. Every winter groups of sandhills migrate from Grays Lake National Wildlife Refuge in Idaho to the warmer climes of Bosque del Apache. Naturalists are concerned that diminishing wetlands are leading the water birds to overpopulate this refuge.

A blanket of clouds shrouds the Chicago skyline in the metropolis that poet Carl Sandburg dubbed "the city of the big shoulders."
The "stormy, husky, brawling" Chicago of Sandburg doubled and tripled in population after 1850. It saw the first skyscraper rise in 1885 and the tallest in 1974. Once known for its meatpacking industry, the city today runs on finance, shipping, and iron and steelworks.

Crop Dusting, Brawley, California, 2005
Photograph by Gerd Ludwig
A setting sun casts a fiery glow over a crop duster spreading pesticides in a Brawley, California, field. In addition to controlling insects, bacterial diseases, and weeds, crop dusting can be used to apply fertilizers, delay fruit ripening, increase or decrease the number of fruit a plant produces, and defoliate plants to facilitate harvest. Biologists and farmers continue to weigh its costs and benefits.

Turtle, French Polynesia, 1997
Photograph by David Doubilet
Like a baby bird embarking on its first flight, a just-hatched turtle, flippers outspread and eyes wide, swims just below the ocean's surface in the waters of French Polynesia. In addition to a dazzling variety of wildlife, including several marine turtle species, the archipelago's rich lagoons spawn a treasure available in few other places: black pearls.
