Being vegetarian is easy and healthy. I recommend it. If nothing else, buy a nice cookbook and make it a habit to cook nice non-meat food one night a week. Make it a date with your partner!
It's worth reiterating that there's a whole continuum between eating meat and eating no meat called "eating less meat". Always amazes me how people overlook this when writing off reduced meat consumption as not for them.
Vegetarian Cooking for Everyone by Deborah Madison is a great way to start down this path.
Thanks for pointing that out. I'm not a vegetarian, but when I order a veggie burger I'm often asked if I am.
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!")
