Do meat-free meals serve up a genuine low-carbon lifestyle?

Recently, I saw a slogan on a subway billboard: "A low-carbon life means eating no meat." And in the company canteen, when I asked a colleague why she picked out all the meat in her meal, she answered, "This is a low-carbon life. You're out."

"Low-carbon life" has become a popular catchphrase that reflects a pro-environment and prohealth lifestyle. Promoting the low-carbon lifestyle has become a social trend.

I reckon you have heard such views. However, I doubt if it is really all that bad and "high carbon" to eat meat.
