Who is legally responsible for deaths caused by air pollution?

A person's death is deemed unnatural when it is the result of an external force. This definition, however, does not apply when the cause of death is a respiratory or cardiovascular process triggered by a high concentration of an air pollutant, even if other deaths from toxicological causes (poisonings, overdoses, etc.) are. The distinction between natural and unnatural cause of death, although not internationally standardized, is critical in determining wrongfulness and liability, which in turn can have fin...
