simplicity and sustainability - suggestions?

In two weeks, Taylor University will hold its annual honors conference.  This year, the theme is

Simplicity & Sustainability: Flourishing in an Age of Excess

The conference will feature keynote speakers Dr. Read Shuchardt of Wheaton College and poet and author Kathleen Norris (be still my heart; this woman has been like a mentor to me through her books for the last decade, and I can't wait to meet her).

We'll also have breakout sessions:

Brent Aldrich, on art and communities designed for sustainability and flourishing

Ragan Sutterfield, on “Feasting and Fasting: Disciplines of Simplicity and Sustainability”

Dr. Michael Guebert, on “Sustainability and Stewardship: Cultural Cliché or Christian Calling?”

Panel: Jane Cramer, Karen Crandall, Megan Miller, Amy Peterson, & Michelle Welker “Simplicity and Sustainability: Practical Solutions for Everyday Life”

  

I'm so excited about this conference.  As a companion to our panel discussion, I'm putting together a resource sheet for attendees, and I'd love your input.  What books, films, websites, apps, etc have helped you make steps towards simplicity and sustainability in your everyday life? (Here's what I have so far.)

Leave ideas in the comments!  Thanks.
