Thoughts on reducing one's ecological footprint

Today we visited the library.

Our books are slowly starting to take over the house... and when I think of all the paper that is needed to print a book and the trees that are felled to make that paper... I just say to myself that I should first borrow the book, and then decide whether it's worth buying for posterity (i.e. the munchkin).

I'm currently reading 'Brideshead Revisited' by Evelyn Waugh, a suggestion prompted by the Mitford reading that I've been doing lately.
What's more, the library even has the dvd of the series.

Hours of enjoyment guaranteed.

Next stop, a Toyota Prius or solar panels? I'm fed up of being the equivalent of an ecological Bigfoot...
