Without repeating definitions, please describe a connection between environmental and occupational health in your own words.
Environmental health and Occupational health can both threaten an individual's life. Environmental health is a persons state of complete health and wellness in their personal day to day life. Occupational health is a person's state of complete health and wellness in the person's work place.

The same connection can happen the other way: a person's environmental health in their personal life affects their occupational health in the work place. Both environmental health and occupational health can overlap in this way.
