The Human Impact
- In 1993, just 27 percent of the land had no measurable human footprint. By 2009, that had grown by 9.3 percent, or 23 million square kilometers.
- While population increased by 23 percent, the average score for the human footprint increased by just 9 percent.
- During that same 16-year period, the global economy has grown 153 percent, 16 times the rate of footprint growth.
- The footprint more than doubled in areas such as the New Guinea mangroves and the Purus Varzea rain forest in the Amazon, and it jumped more than 1,000 percent in the Baffin coastal tundra. The Torngat Mountain tundra saw an increase of more than 10,000 percent.
