These are called sentinel animals or indicator species. A dog barking at noises that people cannot hear is an obvious example. More interesting are certain species in a marine environment that are sensitive to low levels of pollution. For more than a century canaries were used in coal mines to detect toxic gases.
Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity.It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel …
