Thank you for supporting additional research to determine the best way to rid ourselves of the scourge of smog. After living with this smoky menace for decades, it is particularly distressing to realize that our efforts at eradication are based on such minute amounts of data.
Organizations such as the Coalition for Clear Air support the findings of the Air Resources Board and will continue to press for greater research into the causes of smog so that we may hasten its permanent departure. As The Times recognizes, these efforts are strongly supported by the vast majority of Californians still yearning to breath free.
