Well, I already mentioned The Earthling's Handbook as something you
could link to, but I don't see it on your links page...
This page has a lot of specific ideas for reducing your personal
environmental impact: http://www.earthlingshandbook.org/dolist
We also have this page with ideas for celebrating Earth Day:
http://www.earthlingshandbook.org/earthday
and several other environmental articles.
The links you have up are a good start! And thanks for mentioning the
discount on EcoFluxx; I still have not had a chance to play it, so I'll
take this opportunity to get my own deck!
