In May 1889, Carpenter wrote a piece in the "Sheffield Independent" calling Sheffield the laughing-stock of the civilized world and said that the giant thick cloud of smog rising out of Sheffield was like the smoke arising from Judgment Day, and that it was the altar on which the lives of many thousands would be sacrificed. He said that 100,000 adults and children were struggling to find sunlight and air, enduring miserable lives, unable to breathe and dying of related illnesses.
