Second Nature is a nonprofit organization designed to help colleges and universities make environmental sustainability a "foundation of learning and practice." A basic premise of Second Nature is that "moving society on a sustainable path will require major changes in the process and content of higher education." The newly updated site offers current EFS (Education for Sustainability) resources for teachers and educators, including dozens of examples of teaching methods and techniques, a bibliography of over 1800 educational resources, examples of 250 course syllabi, and a collection of essays and publications. The site also allows users to communicate with educators via the bulletin board or browse upcoming events on the Calendar.
