Ecotourism—seeing the world in all its fragile beauty while leaving the smallest footprint—is a major initiative for the Audubon Society. Spotlighting a dozen extraordinary destinations, each one rich in geographic and geologic wonders and teeming with flora and fauna, Audubon's Green World is a brand-new calendar that celebrates the joys of green travel. Journeying from the outback of Australia to Costa Rica's rain forests, from the geysers of Yellowstone to the volcanic islands of the Galapagos, from the rugged highlands of Peru to the pristine coral reefs of Belize, this calendar is utterly seductive. Each month features a large full-color photograph plus dozens of smaller photos in the grid below. And the accompanying text highlights the destination's distinctive features.
