So last night on the local news they had a report about some different ways of "going-green."

I try to do my part in helping the environment, although I know I'm coming up short in some areas, at least I'm retraining myself to think about the lasting effects of things, but one thing they mentioned on TV last night really caught me by surprise.

Using the local Library vs.purchasing books, DVD's, or other media.  By reducing the number of copies in circulation of books, we would be reducing the amount of paper needed to produce such books, print, etc.  This is a grand idea in theory, but most libraries struggle to keep up with new print and marketing tools.  Largely in part due to funding most likely, but how many REAL ESTATE topics could they carry?  There is a wide variety of ideas and theories, and so many are on-line or video or DVD, what is the chance the exact topic I'm looking for would even be at the library.  On top of having a fairly limited selection at my local library (I went and looked, pretty small amount of material to view), almost all of it was from the 1960's or earlier.  A lot of it didn't really apply to Real Estate anyways, more on sales in general, or retail sales. 

My question is, besides the idea of using the library, what other "green" ideas have you heard that either work or don't work.  I am curious to see some of the far-fetched and not so far-fetched ideas out there.
