We tend to overlook how changes we bring to environments affect us in turn. As Christine Kreuder Johnson from the Epicenter for Disease Dynamics notes, «spillover of viruses from animals is a direct result of our actions involving wildlife and their habitat. The consequence is they’re sharing their viruses with us.» ln the late 1960s zoologist Desmond Morris wrote The Naked Ape and The Human Zoo, comparing human and animal behavior. For Morris,
The zoo animal in a cage exhibits all these abnormalities that we know so well from our human companions. Cleary, then, the city is not a concrete jungle, it is a human zoo. The comparison we must make is not between the city-dweller and the wild animal, but between the city-dweller and the captive animal.
