Greater Baltimore Group

Welcome to the Greater Baltimore Group of the national Sierra Club. The Greater Baltimore Group includes Baltimore City, Baltimore County, and Harford County. This page contains local events, outings, and any information dealing with local Sierra Club causes. We focus on local issues, however we do get involved in national campaigns using the information supplied to us by our national organization in San Francisco.

Want to learn more? The Sierra Club is most effective when our members show up at community meetings or hearings or contact their elected officials to voice their opinions and advocate for the environment. We can use email to contact you more than the four times a year the newsletter affords us, in order to let you know about upcoming meetings, important legislation, etc. If you want to join this environmental hot-mail, give your email address to Seth Bush at seth.bush[@]

An important paper by Tom Horton, The Baltimore Sun’s long-time environmental reporter and author of several books about the Chesapeake Bay, questions whether Smart Growth, whatever its potential, can restore the Bay to health while the Bay area population continues to grow. Mr. Horton says the investment of 25 years and billions of dollars in Bay cleanup has been “a failure,” neither reducing the most important pollutant nor increasing the numbers of the most valued marine life. He provides evidence linking that failure to continued massive growth of the Bay area population. 

Mr. Horton's paper, entitled "Growing! Growing! Gone! The Chesapeake Bay and the Myth of Endless Growth" and dated August 2008, is on the website of Baltimore’s Abell Foundation in two versions. The full version is at A condensed version of only 7 pages is at
