There are some valid points there Charm, I have to admit - unfortuantely knowing the publishing industry like I do though most books are not printed on recycled paper (although more are than used to be), and neither are they printed locally. They are printed, like the E-reader in the Far East, using chemical laden inks. It is also common place to print far too many of them - so vast amounts end up being pulped. I realise it is difficult to know how many should be printed, but there are alternatives to lithographic printing, which are similarly priced - print on demand for one. There are many advantages to this method, for both author and publisher - ease of making changes, faster turnaround - no warehousing fees to worry about either.
Cynic as I am, I still think that this is the main reason for hostility towards POD - and E-books by the industry - they fear (and quite rightly so) that it will lead to job losses - for the middle men will no longer be needed. That though is a few years down the line.
Although I find the idea of helping charity appealing by giving old books to charity shops etc, authors also have to live. I would love to be able to write full time, but it is very hard to live on that, so I have to work elsewhere. Personally then I quite like the idea of people not being able to pass my books around - if they want one, let them buy it - it is good to help charity, but authors are not charities themselves ... It is very easy after all to lend books to friends, but would you lend them your E-reader?
The industry needs to put safeguards in place to make sure that authors are adequately compensated for their work when it is downloaded and formatted as E-books. If they don't then we may see a repeat of the Writers Guilds strike, not by Hollywood, but by authors.
