In 1950, Australia released the Myxoma virus as biological warfare against its invasive rabbit population. The virus killed 99.8% of infected rabbits within two years

Australia grappled with a catastrophic rabbit overpopulation that put its ecosystem and economy at risk. To combat this, scientists unleashed the myxoma virus in 1950, which significantly curtailed rabbit populations. Over the years, the rabbits adapted alongside the virus, resulting in a new equilibrium. Subsequently, the introduction of Rabbit Calicivirus Disease further aided in managing their numbers, showcasing the complexities of invasive species, biological control, and evolutionary dynamics.
