NASA | Human Consumption of NPP

On Dec. 14, 2010 NASA Goddard researchers will conduct a press briefing at the American Geophysical Union Fall 2010 meeting, entitled, "Satellite Supported Estimates of Human Rate of NPP carbon Use on Land: Challenges Ahead." In the first measurement of this trend, the research showed humans are using an increasing amount of Earth's annual production of photosynthetic land plants and that consumption rose from 20 to 25 percent from 1995 to 2005.
