That's scary. I guess we all ought to go vegetarian, and protest those coal power plants.
Luckily I live in Europe where some people (of the governement) care about this.
Vegetarian Cooking for Everyone by Deborah Madison is a great way to start down this path.
I eat meat once a week or so, and would have a hard time passing on some of the cultural norms around meat (Thanksgiving turkey, etc.) but eating 90% less meat means 90% lower meat-related emissions.
Of course, if your reason for being vegetarian is animal welfare and ethics, then this rings hollow ("I commit 90% fewer murders!")
