Change in the Distribution of Wilderness and Globally Significant Wilderness Areas since the Early 1990s
Globally significant wilderness areas are defined as wilderness areas >10,000 km2. The insets are focused on the Amazon (A), the western Sahara (B), the West Siberian taiga (C), and Borneo (D).
We've lost roughly 1.2 million square miles of wilderness since the early 1990s, leaving 12 million square miles still intact.
