Beginning about 1000 ce, the use of coal for fuel caused considerable air pollution, and the conversion of coal to coke for iron smelting beginning in the 17th century exacerbated the problem. Although urban areas are usually more polluted than the countryside, pollution can spread to remote places where no people live. A lack of sanitation and sanitary waste management systems can reduce a community's access to clean water, and lack of access to clean water can allow diseases to run rampant, sometimes creating epidemics of water-borne infectious agents.
