Infectious disease and biosecurity are two of the most pressing scientific issues facing society. Global change is a driving force for emerging infectious diseases. A growing human population, increased global connectivity, urbanization, climate change, and intensive farming practices are examples of changes that create a greater connection between people, animals, plants and the disease agents each carry. These connections create opportunities for the emergence of infectious disease. Biosecurity is how we prevent and control for emerging infectious disease, and is a means of protecting the planet’s resources.
