Public health is important to every one, every day because it focuses on the prevention of disease, injury, and premature death.
Public health takes a population-based approach to addressing the root causes of health issues.
By addressing unhealthy behaviors and environmental threats to health, public health is able to make a greater impact on people's quality of life. Public health is widely credited with increasing the life span of Americans by 25 years this century, more than medical technology, genetic research, and other scientific developments.
