I want to encourage participation in this National Resources Defense Council action alert. Follow this link to send an email voicing your support for the New York City Green Buildings Bill. Though many readers do not live in New York City or the region, I believe all comments are significant, especially since NYC fancies itself the country's cultural leader.
Also, Sustainablog has been on a roll lately, offering some informative tidbits for folks interested in sustainable development and environmentalism. Initially, I responded well to the information communicated on Sustainablog, but didn't take to the "blurb" approach. Over time, however, I've realized that it one of the best sources for links and updates pertaining to the field.
Jeff, Sustainablog's founder, also has a post up about the work of Edward Burtynsky, one of my favorite contemporary photographers. Visit Burtynsky's site.
