Yet another clown gaining the ear of the media. How much noxious emission did the 150,000 kilometre epic journey create. To use the words "expansion of kangaroo farming" indicates that we have kangaroo farms in Australia. Will one of these so called Drs please explain where one can view a productive kangaroo farming enterprise in Australia?

Quick! Somebody call in theRSPCA and/or the WWF to preserve the roos from this devastating rise in temperature. Otherwise, how are we to make a quid out of roo meat?

Another tax-payer funded junket all in the name of the great global warming scam.

I have never heard so much rubbish in all my life!! Who is paying these idiots?

The only "Kangaroo Farming" that I am aware of are shooters with spotlights.

Kangaroos are wildlife and cannot be "farmed". They are "harvested" (massacred) for their little meat, and skins. Millions are killed each year. They don't need climate change to kill them! Kangaroos are small and grow slowly, and their meat could never replace the amount of red meat we eat and export. The fences would cost too much and they cannot be transported or handled. The blood-lust of this industry has not considered these factors, but only see profits from these maligned and beautiful fauna.

If the world's climate changes and apparently it is doing so, then the Roo population will change with it. When life first began on earth evolution was the making of all of what we have on earth today, you do not think that this is going to stop. If the temperature is warming then their inbuilt genetic make up will keep abreast of this. Nature will not stop just because the World is getting warmer. Man may feel the heat ........ and obvioulsy some people are feeling the heat and it is not hot yet!

If 'Steffi' or your journalists would like to actually read the paper referred to by Prof Garnaut it can be downloaded at www.awt.com.au . It describes how trials are underway to enable landholders to become involved in kangaroo use and benefit from it. It does NOT advocate keeping kangaroos behind wire but collaboration between landholders in regional management of kangaroos the same as is done for other wildlife species overseas. Pastoralists already carry 30 million kangaroos - surely it is time for them to benefit from their contribution to conservation. In regard to Dr Ritchie's study, your journalist does not seem to have read that paper either. He has missed that the study was in the tropics and has not bearing on the reference by Garnaut. The Ritchie report does not say that the very abundant grey kangaroo is threatened by climate change so why does the Land article say that?

While it is great to have such lively debate regarding this issue, it is a shame that some media outlets and individuals have distorted the facts and only reported part of the story. The full article will be available publicly soon and I encourage you to read it to find out what our research actually found. Our article does not say that kangaroos will go extinct, merely that there is potential for change in distribution, in particular for a northern species, the antilopine wallaroo, which is not currently harvested. Like anything regarding the future it is only a prediction and should therefore be treated with caution as we make clear in our paper. Again please note, we are only talking about Northern Australia, not all of Australia as some media articles have reported. Further, it is regrettable that the issue is being painted as beef versus kangaroo. There is no doubt that in many parts of Australia, livestock grazing represents the best sustainable use of the landscape, and if graziers can supplement their incomes with kangaroo meat (in some areas), as many have told me they'd like to, then surely this is of benefit to everybody? Finally, if it eases anyone's conscience, this research was not funded by taxpayers.

In response to the Editor's note: your article opened with a reference to roo harvesting replacing lamb production. This implies that the results of this study apply to southern Australia, and implicates grey kangaroos. Your article does mention that field work was undertaken across northern Australia, but does not make it clear that the predictions on distribution change were limited to the tropics.
