The One Health Approach: Humans and the Environment


Admission requirements



This course explores the relationship people have with their environment, the risk management choices made, and the resulting associations that affect health and physical well-being for the individual, communities and susceptible populations. The course also emphasizes a “One Health” approach to environmental and occupational health issues that considers the ecological relationships between human, animal, and environmental health. The course examines a representative sample of environmental hazards and major environmental events and media, with comparative local and global case through problem solving approach. Course assignments stress developing basic literacy in environmental and occupational concepts and applying this knowledge to problem solving. As everyone is affected by environmental health principles and topical areas of concern every day; we all eat, drink, produce waste, and breathe air each day. This course delivers important information and resources for the students' own health and wellness advocacy as they move out beyond this institution.
