Humans contribute to this modification through urbanization, agricultural development, manufacturing, recreation, and transportation. These leads to increased risk of transmission of infectious agents due to our close proximity to the natural habitats of these agents “Expanding population centers and rapid growth in animal agriculture are increasing the contact between people and animals, both wildlife and domestic, thereby increasing the risk of transmission of new and resurging infectious diseases” (USGS, 2010).
