Detailed explanation-1: -Their numbers became so large that they destroyed crops and land, leading to soil erosion. They also negatively affected agriculture and plants by overgrazing.
Detailed explanation-2: -Rabbits were introduced to Australia in the 18th century and, lacking natural predators, their population exploded. A virus called myxoma was introduced in the 1950s, and caused a population crash, but the survivors have developed immunity and the population has rebounded.
Detailed explanation-3: -The population is currently estimated to be 200 million. Those rabbits inhabit 70% of Australia’s landmass (5.3 million km2) and are generally widespread wherever they are found.
Detailed explanation-4: -Feral rabbits may have caused the extinction of several small (up to 5.5 kilograms) ground-dwelling mammals of Australia’s arid lands, and have contributed to the decline in numbers of many native plants and animals.
Detailed explanation-5: -Biological Methods In 1950, mosquitoes and fleas carrying the myxoma virus were released into the wild. This virus, found in South America, only affects rabbits. The release was highly successful, as an estimated 90–99 percent of the rabbit population in Australia was wiped out.
