There are countless examples of environmental effects on animals that later manifested in humans. The classic example is the „canary in the coal mine„. The idea of placing a canary or other warm blooded animal in a mine to detect carbon monoxide was first proposed by John Scott Haldane, in 1913 or later.^[2][3][4] Well into the 20th century, coal miners brought canaries into coal mines as an early-warning signal for toxic gases, primarily carbon monoxide.^[5] The birds, being more sensitive, would become sick before the miners, who would then have a chance to escape or put on protective respirators.
