We have all heard the warning that frogs put in a pan of water will remain there so long as the water is brought to a boil very slowly. The analogy is often used to call people to action in slowly developing crises such as climate change. Fortunately or unfortunately, the analogy is a wive’s tale according to Snopes (see link below). Frogs will not sit while their environment slowly becomes lethal. Apparently human beings are the only species that will do that.
