There are so many ways to gauge your own green, but one of the ways I think many of us conveniently “forget” is the impact our cool new gadgets have. The NYT gives us the stats on whether old-fashioned books are more environmentally sound that an iPad (or other forms of eBooks).
The short version: walk to the library. Books win, really. If you read at least 100 books on your eBook, you don’t suck entirely.
