| The vast majority of trees which are cut for paper pulp are
| quick-growing loblolly pines which will be re-planted almost
| immediately, larger, older, nicer trees are usually cut for

| Here's a page which indicates most CO_2 production is for
| energy: http://www.eia.doe.gov/oiaf/1605/ggrpt/carbon.html
|
| And here's a page which indicates that CO_2 production is a
| much larger problem for the manufacturing of electronics:
| http://www.energybulletin.net/node/49730 w/ a ratio of 12 to
| 1 for energy usage to weight, so my PRS-505 weighs roughly 9
| ozs., so presumably required 108 ounces of fuel to
| manufacture (on-going energy usage is not considered)
| http://www.epa.gov/oms/climate/420f05001.htm gives us a
| figure of 19.4 pounds of CO_2 per gallon of gasoline which
| equals roughly 16.36875 pounds of CO_2 to make the ebook
| reader.
|
| So getting two books for the Sony should make it roughly
| break even, and each printed book beyond that which is not
| purchased should result in a net reduction of CO_2 emissions,
| since the energybulletin.net page indicates that the embodied
| energy usage for electronics is much greater than the
| lifetime usage
