The diversity, majesty, and beauty of the natural world, captured by Frans Lanting, Art Wolfe, and more of the world’s top nature photographers. A blue-tinged iceberg floating off the Antarctic. A pair of lionesses in profile. China’s ancient Dragon’s Backbone rice terraces. And a flock of red-and-green macaws in the Peruvian Amazon. From the organization synonymous with peaceful environmental activism, the Greenpeace: Standing Up for the Earth calendar is a poignant reminder of what is at stake. These images are spellbinding. As always, royalties from the sale of the calendar support the work of Greenpeace.
