As noted in the previous Managing Editor s Comment (MEC), the theme of the ACS Spring 2010 National Meeting concerns sustainability. We continue to have a healthy stream of research content and front matter addressing quantitative and qualitative sustainable practices. For example, the previous MEC spoke to determination of boundaries in life cycle assessment(s) (LCA). Another example appears herein with Huijbregts et al. (Environ. Sci. Technol. DOI 10.1021/es902870s) investigating the energy demand in commodity production. Also noted was streambed management, especially given that issue's Feature by Hester and Gooseff (Environ. Sci. Technol. DOI 10.1021/es902988n). In this March 15, 2010 issue, Roth et al. (Environ. Sci. Technol. DOI 10.1021/es902654f) present the use of riparian vegetation to cool streams and thus mitigate fish kills-certainly a more sustainable approach to ecosystem management than built structures?
