Two-thirds population cut or four more planets needed

January 2006
Sustain' Magazine;2006, Vol. 7 Issue 1, p8
The article reports on the results of a study on the impact of world population on the prevention of climate change. Results indicated that more than twelve extra Earths would be required if the population of the world consumed fossil fuels at the rate the U.S. is now doing. According to the analysis of the carbon absorption capacity of the Earth and ecological footprinting techniques, replacing fossil fuels with renewable energy may not be sufficient to supply a rapidly growing population with its energy needs.
