Interesting, but I'm having trouble grasping how grazing cattle could have a net positive impact on carbon emissions...

Cows are not very efficient in terms of converting cellulosic material into useable energy and about 30% of the biomass they consume will be released into the atmosphere as methane and other gases, however, while 100% of that biomass the cow ate was growing from the ground, it was converting CO2 and H20 (two potent greenhouse gases) into sugar and O2 at 100% efficiency and, furthermore, the grass that replaces it will do the same. How is it that cows are actually adding carbon to the atmosphere?

I'm not a climatologist, but it isn't making sense and I hope someone can explain that to me...

add in the fact that rainforests are cut down for land to have cows graze and you get even more of an impact.

Ok, it makes sense that re-purposing areas of dense, old-growth foliage as grazing pasture would be bad, but I wish Mr. Guretzky had quantified the information in the Noble Foundation brief. Just a touch underwhelmed.

I feel better about all the venison and waterfowl in my freezer, though.

The research on the Inuit diet directly contradicts that, showing a high fat, high meat diet can be quite healthy.

Rainforests are also being cut to grow sugarcane, soybeans and fruits too.

To show how absurd that argument can get...it leaves out all the wild animals.

Because we aren't just feeding them grass. If they were free grazed cattle, then they wouldn't be putting out that much in harmful gas. However, we feed them, genetically engineered corn, left over cow, and steroids that increase their growth rate, increase their output of methane gas, and harm the environment even more then they would have naturally.

For me, I sometimes eat meat. There isn't anything I would not eat if it was put on my plate. I might not like the texture, but since I have no taste buds, it has nothing to do with the taste. Probably because I was basically starved as a child, so I never want to pass up food. The only thing that keeps me from buying meat or fresh vegetables is the COST. Too expensive, really, to eat as an every day thing.
I eat meat because I like it.
I have no desire to debate my way of life regarding what I eat. If someone else feels the need to be a vegetarian, then have at it. Why should I care about their choice and why should they care about mine?
