A colleague suggested the Industrial Designers Society of America Ecodesign Section site as a source of extensive information on materials and curricula and links relevant to eco literacy [thanks Heather!]. It is a site that will take a while to explore since it is extremely rich.

The links section alone is worth the visit!
