Davyd Madeley writes about vegetarianism for the environment  which is listed in Wikipedia as Environmental Vegetarianism . He links to an article on the Huffington Post . The Huffington Post article in turn links to an article on GoVeg.com about global warming .
Mass-produced meat is not only bad for the environment but there are also health issues related to meat consumption (due to bad practices in mass farming, combining the meat of thousands of animals into mince thus increasing the spread of bad meat, and the fact that most people in first-world countries consume significantly more meat than anyone did at any time in history).
One thing that doesn’t get mentioned in these posts is the fact that farming is not required to produce meat. In fact the meat that is most healthy (due to lack of carcinogenic chemicals and free-range feeding) and has the strongest flavour (which may be a good or bad thing depending on whether you actually like the flavour of meat) is from wild animals. If you don’t like the taste of meat (which seems to be the case when people don’t like game meat) then why eat it at all?
In Australia large numbers of kangaroos are killed because they eat grass more efficiently than cattle (they have evolved over tens of thousands of years to survive in Australian conditions unlike cattle). There are also a number of foreign animals that have run wild in Australia and are considered vermin, this includes rabbit, pig, buffalo, deer and camel (all of which are tasty).
Even among native animals there are often times when a cull is needed. If some good seasons allow the population to increase then when there is a bad season the population has to reduce and it’s often better for them to be culled (thus providing plenty of food for the surviving animals) than for all of them to starve.
There is a game meat wholesaler I’ve visited a few times that sells buffalo, rabbit, pig, camel, crocodile, possum, emu, kangaroo, and some other animals. All of the meat is from wild animals (apart from rabbit and pig none of those animals can be domesticated). I’m sure that every region has such a wholesaler that will sell to interested individuals if you know where to look (it seems impossible to buy any game meat other than kangaroo retail in Australia).
Finally one thing that offends me is people who eat meat but are not prepared to kill the animal. If you aren’t prepared to kill it then you shouldn’t pay someone else to do so on your behalf! Claiming that “the animal was going to be killed anyway” is a pitiful excuse that is only suitable for children. It’s acceptable for children to eat meat without thinking about where it came from. But adults should be able to deal with the fact that eating meat means killing animals – or become vegetarian if they can’t cope with it.
The book 3001 The Final Odyssey pioneered the term “corpse food” for eating meat. I believe that the term is accurate and should be used. If you can’t stomach eating corpses then there are many good vegetarian options available.
There are many vegetarians in the Linux community. As these issues are getting discussed a lot recently maybe it would be good to have the vegetarians choose some good vegetarian restaurants to have Linux meetings on occasion. Davyd got a bit of negative feedback on his post, maybe if he invited a bunch of his local Linux people to have dinner at a vegetarian restaurant and they enjoyed the food then the reaction to such ideas would be more positive.
