Das Drei-Steine-Feuer wird von der Population der Entwicklungsländer dafür das Kochen abhängen; aber die Gesundheit der Umwelt und der Leuten werden von dem Drei-Steine-Feuer hindern.
A large population of people in developing nations depend on traditional three rock fires for cooking; this primitive form of cooking negatively impacts the health of people using the stove and the well being of the natural environment. Two billion people use biomass for cooking and heating worldwide. Traditional three rock fires are used inside the persons dwelling, usually located on a dirt floor. "Over the last 30 years awareness of the environmental and social costs of using traditional fuels and stoves has grown." <ref name="Bryden">Bryden, Mark., Dean Still., Damon Ogle., and Nordica MacCarty. 2001.

Traditional three rock fires pose major obstacles to the environment, social health and [[sustainability]] of society. The most important concern with traditional three rock fires is [[indoor air quality]]. Biomass fuels release large amounts of air pollutants when burned on traditional three rock fires. These pollutants become concentrated in inadequately ventilated homes and dwellings. "Several recent studies have identified prolonged exposure to biomass smoke as a significant cause of human health problems." <ref name="Barnes">Barnes, D.F., K. Openshaw., K.R. Smith., and R.V.
