Also (and I'm not sure if the UK version does this as well), the Canadian books are printed on 100% post-consumer recycled paper so they are considered "ancient forest friendly". When you consider the huge numbers of sales this book generates, every little bit helps!
Apparently we're not quite so... enlightened
. What my copy says is:
The pages of this book are printed on 100% Ancient-forest friendly paper
(So far, so good.)
Then:
The papers on which this book is printed are manufactured from a composition of (c) 1996 Forest Stewardship Council A.C. (FSC) approved and post-consumer waste recycled materials. The FSC promotes environmentally appropriate, socially beneficial and economically viable management of the world's forests.
So, some of the UK edition's materials come from recycled materials... but only some.
Yay, the Canadians!
