Isn't it funny that "Harry Potter's Lasting Legacy" is the amount of waste/pollution/clearcutting avoided?!  How silly.  So HP is efficient: who cares?  Reducing is not inherently good.  If you're driving 100 mph toward Canada, but suddenly realize that you should be going to Mexico, it's not going to help you to slow down to 20 mph.  Efficiency means nothing when HP is still responsible for the loss of a great number of trees (which should be sequestering carbon right now instead of sitting on bookshelves...).  

And, how long will the books she IS printing last, and what landfills will they go to when they are at their end?  How many millions of books are out there, waiting to be someday thrown away?

(By the way, I'm a Harry Potter fanatic.  I'm buying the book instead of waiting for a library copy to free up, even though I don't approve of it.  There.  Now you can't call me a hypocrite because I just did!  Expelliarmus!)

It turns out the greenest book of all time was written by myself.  It has not been published, nor will it ever be - in fact, it only exists in electronic form.  By keeping it from being published, I've essentially  saved an infinite amount of resources that could've been used to print and distribute it.  So there.  I win.  Greenest book of all time.

The last couple Canadian editions were published on recycled paper, but the US ones weren't. So do we still have to invade Canada to get this eco-friendlier paper?

Read again more carefully, and it does say it's the U.S. too. Okay, I'm back in line, not walking to Canada.
