Lesson 17-2 A man-made disease
It effectively spread the disease all over the continent and drastically reduced the
rabbit population. It later became apparent that rabbits were developing a degree of
resistance to this disease, so that the rabbit population was unlikely to be completely
exterminated. There were hopes, however, that the problem of the rabbit would become
manageable.
Ironically, Europe, which had bequeathed the rabbit as a pest to Australia, acquired
this man-made disease as a pestilence. A French physician decided to get rid of the wild
rabbits on his own estate and introduced myxomatosis. It did not, however, remain
within the confines of his estate. It spread through France, Where wild rabbits are not
generally regarded as a pest but as sport and a useful food supply, and it spread to
Britain where wild rabbits are regarded as a pest but where domesticated rabbits,
equally susceptible to the disease, are the basis of a profitable fur industry. The question
became one of whether Man could control the disease he had invented.
