This Agence France-Presse article reports the "culling" of kangaroos in Australia as though this was something new. It is not new and I'm not sure why it is being reported as such.
The other DrC and I were in Oz (aka Australia) last October and were served kangaroo steak on The Ghan, Australia's north-south cross-country passenger train. I didn't much care for it, because it was gamy, as venison often is. We were also served a sort of kangaroo-based salami that was quite good.
The folks who run Australia's huge sheep stations (i.e., ranches) have been killing kangaroos forever, as the roos compete with the sheep for scarce grass. We were also in Oz in 1985, riding the east-west cross-country passenger train called the Indian Pacific from Sydney to Perth. Somewhere in the countryside not far from Broken Hill the train passed a truckload of dead kangaroos, stacked like cord wood, headed for a knacker or pet food plant.
