That study was so flawed, it's not even funny. It took one specific scenario in Australia, where farmers had to kill a lot of rodents (due to a seasonal plague) to protect their crop and compared that to a single animal slaughtered for a meat dish. They completely failed to mention that livestock are fed that exact same crop, that the farmers were killing the rodents for. IIRC there a couple such "studies", but all similarly flawed.
