What disease was introduced to control rabbits in the 1950's?
Myxomatosis (sometimes shortened to "myxi" or "myxo") is a disease which affects rabbits. It is caused by the Myxoma virus. First observed in Uruguay in the late 1800s. It was introduced illegally to Egypt in 1842 and as a result spread to the rest of Africa. It was deliberately introduced into Australia in 1950 in an attempt to control rabbit infestation and population there; see rabbits in Australia. It was also deliberately introduced in the UK to try and reduce the rabbit population after World War II.
Why was myxomatosis designed to be deliberately disabling?
Myxomatosis was intentionally designed to disable rabbits as a way to control their population. The virus causes severe symptoms, such as swelling, blindness, and ultimately death. It was introduced as a biological control measure to reduce the number of rabbits, which were considered pests in certain regions.
How did the Rabbits in Australia upset the Balance of Nature?
In Australia in the 1950s, the rabbit population was so large that they ate the land bare and erosion set in, making the land infertile. The government attempted to reduce the rabbit population by introducing foxes, wire fences and poisons, but nothing worked. Finally, they intentionally infected rabbits in the most populated areas. The virus was transmitted from rabbit to rabbit by insects. Over the next three years rabbits died by the millions, agriculture rebounded and everybody was happy. Then, unfortunately, there was a sudden upset in the balance of nature. The Explorit Science Center reports that the virus had been successfully introduced into European rabbits too and, "with a scarcity of rabbits, foxes began eating poultry, rats and mice. The resulting reduction in the numbers of mice caused a decline in the numbers of owls whose normal diet (mice) became less abundant" - and this disruption continued down the food chain (explorit.org).
Why haven't viruses wiped out the human population?
Viruses haven't wiped out the human population due to many people being able to take enough precautions to avoid it all together. Other people are immune to certain viruses that might prove fatal to others. Also, vaccines have been created to reduce deaths among illneses such a the cold virus, flu, fever, etc. So: -taking precautions to avoid the virus -Being immune -Vaccines are just a few answers to why the human population hasn't been wiped out by viruses. Oh, and because we reproduce rather frequently.
