This button likely refers to and promotes clean air and air pollution control. When the air changes to the color gray, it is referred to as smog. In the United States, smog was brought to attention in 1933 after the publication of the book “Stop That Smoke,” by Henry Obermeyer. The United States later enacted the Clean Air Act in 1963 to control air pollution on a national level. Throughout history there have been major air pollution events, such as the event on November 24, 1966 in New York City, when smog killed at least 169 people.
