Sickness in Australia
From ANIMAL PEOPLE, November 1996:
SYDNEY, LONDON– – Intro-
ducing a pest to control a pest, against
much scientific and humane advice,
Australian agriculture and wildlife authorities
in mid-October released millions of calicivirus-carrying
Spanish rabbit fleas at 280
sites, expecting to kill up to 120 million of
the nation’s estimated 170 million rabbits.
The rabbits are accused of outcompeting
endangered native marsupial species
for habitat––though they also draw predation
by feral foxes and cats away from marsupials––and
of costing farmers $23 million
to $60 million a year, chiefly by eating fodder
that would otherwise go to sheep.
Calicivirus induces internal hemorrhage,
killing about 90% of the rabbits
who contract it within 30 to 40 hours. It
spreads at about 25 miles per day.
