I have been following the many articles on air-pollution and related articles for more than 2 years. It is not only informative but written by people with passion for the earth and conviction. Someone once told me how far can you go with one lone voice but my response to that person was together, we can make a difference. Dr. Margaret Mead (1901-1978) world renown anthropologist said: "Never doubt that a small group of thoughtful committed citizens can change the world: Indeed it's the only thing that ever has." I have always quoted her whenever I was posed with the same question.
