Canaries were used in mines from the late 1800s to detect gases, such as carbon monoxide. The gas is deadly to humans – and canaries alike – in large quantities, but canaries are much more sensitive to small amounts of the gas, and so will react more quickly than humans. This was discovered by John Haldane, who was asked to help
