Yes, I agree, Lizbud...what animal will be next? And there ARE other humane ways of reducing numbers.
Presently, there are too many koalas on Kangaroo Island here in Australia. When culling was mentioned, there was much public opposition. And now the authorities have had to consider other acceptable methods.
If there are not enought people objecting to kangaroos being slaughtered, then it may become easy to slaughter koalas, too.
