Dazzling in its imagery and powerful in its message of conservation, "Greenpeace" features a dozen full-color portraits by the world's top nature photographers, including Art Wolfe and Frans Lanting: emperor penguins waddling across an ice floe. A manatee and her baby gliding through glassy Florida waters. Alaska's tundra turned into a tapestry of red, yellow, and orange fall foliage. From the expressive face of a Japanese macaque to a Scottish woodland abloom with bluebells, each picture is a poignant reminder of just what is at stake. As always, all royalties from the sale of this calendar go to support the work of Greenpeace.
