Final answer:
Health hazards are subdivided into traditional hazards and modern hazards. Traditional hazards are related to poverty and lack of development, while modern hazards are caused by development without environmental safeguards.
Step-by-step explanation:
Under the new system, health hazards are subdivided into two broad categories: traditional hazards and modern hazards. Traditional hazards are related to poverty and lack of development, and they mostly affect developing countries and poor people. Modern hazards, on the other hand, are caused by development that lacks environmental safeguards and prevail in industrialized countries. These modern hazards include urban air pollution, exposure to agro-industrial chemicals and waste, and other risks associated with technological development.
