The use of fire for heating and cooking came with exposure to smoke outdoors and indoors, an exposure that persists today for the billions who use biomass fuels for cooking and heating. The rise of cities concentrated the emissions of pollutants from dwellings and industry and led to air pollution that received comment and was considered a danger to health. The problem of air pollution received attention centuries ago in London, polluted by widespread coal burning.2 However, regulation was resisted even then.
