What caused the recent population spike of rabbits in Australia?
A weather pattern called El Nino, the warming of ocean surface waters which blow warm air over the continent.
A weather pattern called La Nina, lots of warm wind and rain made temperatures ideal for reproduction
An increase in global warming makes it warm all year so the rabbits can reproduce
at a faster rate.
Introduction of European rabbits in Australia by early settlers, leading to a lack of natural predators and allowing the rabbit population to thrive.
Lack of effective control measures, such as hunting or sterilization programs, to keep the rabbit population in check.
