Five stunningly large forests remain on Earth: the Taiga, extending from the Pacific Ocean across all of Russia and far-northern Europe; the North American boreal, ranging from Alaska's Bering seacoast to Canada's Atlantic shore; the Amazon, covering almost the entirety of South America's bulge; the Congo, occupying parts of six nations in Africa's wet equatorial middle; and the island forest of New Guinea, twice the size of California. These megaforests are vital to preserving global biodiversity, thousands of cultures, and a stable climate-and saving them is the most immediate and affordable large-scale solution to our planet's most formidable ongoing crisis. Clear, provocative, and persuasive, economist John W. Reid and celebrated biologist Thomas E. Lovejoy's Ever Green is an inspiring call to action to conserve Earth's irreplaceable wild woods.
