The comments are already frustrating. I could boil the whole being vegan argument down to "less cattle in the world would be a quick and easy CO2 reduction win", and receive mind bogglingly silly arguments in return totally missing the point. Better not go there.
Quick and easy in the sense that the overall impact to society would be minimal. Contrast that to giving up fossile fuels in large scale for example. Or any other change that would have similar impact.
The whole point of making the argument for veganism is to make people understand that they can, and indeed should, make this change. Even if in small steps.
I don't understand the thought process here on HN when people start punching the flagged button the second a controversial subject comes up. I would think the large portion of scientific minded people here would be thrilled to toss around different ideas, but it seems egos and hurt feeling take over and the thread is ultimately killed.

Take a look at comments on more controversial threads, I think you overestimate the userbase.
