Motor vehicles powered by the internal combustion engines are responsible for over 80 percent of the deadly carbon monoxide as well as the cancer-causing substances in the air. Eighty-nine percent of the vehicles on the road in Massachusetts are privately owned and are often operated with only one person in the car. If people would use public transportation instead of their cars, air pollution levels could be significantly lowered. Thirty percent of the land in downtown Boston is devoted to cars. Where there are garages, there could be gardens. Where there are highways, there should be homes and places to work and play. Studies show that people today show a greater hearing loss with age than ever before. Much of this is due to car-horns, loud engines and general traffic noise.
