Vanishing forest: a northern forest is disappearing at a rapid pace--that spells trouble for billions of animals.(LIFE: BIOMES)

Science World | March 27, 2006| | Copyright

A long the rim of Earth's northernmost land-masses sits an ancient forest. Its mix of pine, spruce, and other hardy trees encircles the globe like a giant green halo (see map, p. 19). This interconnected web of trees, mosses, birds, and other organisms is called the boreal forest. It is the world's largest intact forest ecosystem--It's even bigger than Earth's tropical rain forests.

But many regions in the boreal forest (see Nuts & Bolts, p. 20) are under assault. According to scientists, logging, mining, and oil and gas companies are yelling "timber," leveling ...
