Quammen (2012) examines quite a few these zoonoses – disorders arising every time a pathogen leaps from a nonhuman animal to a person and sickens or kills that human being – and highlights the elaborate connections involving biodiversity and new zoonotic disorders.

Occasionally their Increased talents to help make a living outstripped their neighborhood environment’s capacity to provide that living, and so they disrupted regional ecological programs.
