Signs of change are appearing in the United States military as well.

The “Meatless Mondays” campaign was originally thought up to support the war effort during World War I, but now a modern army is using it to fight an even bigger battle—the one against climate change.
Last fall, the Norwegian army announced their plan to join the campaign by preparing their soldiers (both at home and overseas) a meat-free breakfast, lunch, and dinner once a week.
It's not just Norway where the military is concerned about climate change.
"It's not about saving money," said navy commander and nutritionist Pal Stenberg, who runs the catering department. "It's about being more concerned for our climate, more ecologically responsible, and also healthier."
According to the United Nations, the livestock industry contributes almost 15 percent to the total greenhouse gas emissions caused by humans. And a study released by the Proceedings of the National Academy of Sciences found that the global livestock business takes up 30 percent of the earth's ice-free land and 30 percent of fresh water.
