Even as I accept the general scientific understanding of climate change, including the anthropogenic contribution, I'm not sure this march was the most effective way to go about the issue. That there were many non-climate-related messages only muddies the overall message on the scientific understanding of climate change. Attacks on nuclear power, capitalism, etc., may actually strengthen opposition to realistic climate change policy initiatives. If policy makers and the general public are presented with the position that one can only address climate change by abandoning market economics, that position will prove non-viable. Even as there are limitations e.g., externalities, associated with market economics, no better system has been devised and one cannot dismiss the enormous standard of living benefits that have been produced from a more market-oriented arrangement. Realistic and balanced policy approaches, not purist demands, offer the most promising prospect of moving away from "business as usual" in the longer-run. I don't believe this march contributed toward that end.
