Deforestation
Deforestation is changing the global climate.

 
The Scale of Deforestation: Original vs Remaining Forest

From World Resources Institute: The Last Frontier Forests: Ecosystems and Economies on the Edge Major Findings (via Eric Bettelheim, SFM)

Global Figures:

Original Forest (000Km2): 62,203
 
Total Remaining Forest (000 Km2): 33,363

Total Remaining as a % of Original Forest: 54%,

  • Almost half of Earth's original forest cover is gone, much of it destroyed within the past three decades.
  • Today, just one fifth of the world's original forest cover remains in large tracts of relatively undisturbed forest -- what WRI calls frontier forest.
  • Three countries -- Russia, Canada, and Brazil -- house almost 70 percent of the world's remaining frontier forest.
  • 40 percent of forest on Earth today qualifies as frontier forest.
  • Seventy-six countries assessed in this study have lost all of their frontier forest.
  • 39 percent of Earth's remaining frontier forest is threatened by logging, agricultural clearing, and other human activity.
  • Eleven countries -- including Finland, Sweden, Vietnam, Guatemala and Thailand -- are on the verge of losing their frontier forest. These countries maintain less than 5 percent of their original forest as frontier, and all of it is threatened.
