David Buccola asked:

If our current economy is at 140% of Earth's capacity, what does that mean? How is that even possible? I understand the basic problem of a finite planet coupled with an economic system based on infinite growth. I get that. But to say we are at 140% of the planet's capacity seems counter-intuitive, even impossible. Obviously they are still sucking minerals and resources out of the planet. Can someone explain this?

Cary Neeper Here's the answer from the populationinstiute.org
"Sustainability, or meeting the needs of the present without compromising the ability of future generations to meet their own needs, depends on making sure humanity does not use more ecological resources than nature can regenerate. The Global Footprint Network estimates that in the early 1960s, the human species consumed about 50% of the Earth's natural resource capacity. By the mid 1980s, the scale of human activity on the planet reached 100% of the Earth's capacity, and was trending steadily upward. Now, because of continued high global population growth rates and higher consumption patterns, the total anthropogenic (human species) demand on our planet is approximately 140% of its long term capacity."
