Jim Robbins, "The Ecology of Disease," New York Times, July 15, 2012. The expansion of livestock farming into areas where wild animals are in close proximity has been implicated in the spreading of diseases from wildlife to domesticated animals and from there to people. The bird flu, for example, evolves in domesticated animals when it spreads from wild animals. HIV/AIDS spread to humans ninety years ago when African hunters killed chimpanzees and sold the meat for human consumption. The extremely deadly Ebola virus, first identified in the border regions of western South Sudan and northeastern Democratic Republic of the Congo in 1976, originated in chimpanzees, gorillas, monkeys, forest antelope, and fruit bats.
