UNNATURAL CAUSES is a four-hour series that, for the first time on television, sounds the alarm about glaring socio-economic and racial inequities in health and searches for their causes. UNNATURAL CAUSES looks at what's making us sick in the first place, investigating startling new findings that suggest there is much more to poor health than bad habits, inadequate health care or unlucky genes. The series circles in on a slow killer in plain view: the social circumstances in which we are born, live and work that can affect our risk for disease as surely as germs and viruses.
