Human behavior through habitat modification has led to the emergence of infectious diseases “Modification of natural habitats by humans is a leading cause of emerging zoonoses” (Battle, 2009, P 32). Humans contribute to this modification through urbanization, agricultural development, manufacturing, recreation, and transportation.…show more content…

This transmission of diseases between humans and animals has accounted for 75% of worldwide emergence of infectious diseases (Battle, 2009).
