“Canary in the coal mine” is not just an expression referring to an early and often lone warning of danger. The true story of canaries in coal mines offers many lessons for designing environments fit for humans.

On sentinels and sensitivity

Sentinel species are animals or other organisms sensitive to environmental threats and able to react before humans. At different points in history, birds, guinea pigs, mice, rabbits, horses, and other animals had served as sentinels of toxins and other dangers. Canaries were the original carbon monoxide detectors in mines. In the presence of toxic air, birds would show distress before miners were significantly affected. This gave the miners time to evacuate safely and to revive the canary using oxygen from a bird-sized oxygen tank. In the UK, canary birds went underground with the miners until 1986, when........
