So Vegetarians Aren't Weak?: Arnold Schwarzenegger isn't exactly known for embracing a plant-only diet. (There's a scene in Escape Plan where his character taunts Sly Stallone's character by saying "you hit like a vegetarian!"). But the former California governor is changing with the times, and he made waves by suggesting that people go meat-free a few days a week to help reduce the effects of cattle-raising on climate change. "It's a very big challenge but it doesn't mean it shouldn't be done," he told the BBC from Paris. "I have seen many body-builders and (weight) lifters that are vegetarians." [BBC News]
Breathe Easy: The newly released worldwide air map, created by Plume Labs, shows you where air pollution is minimal (looking good, Kansas City!) and downright hazardous (yikes, New Delhi).

Chan School of Public Health. [Harvard Gazette]
Organic vs. Non-GMO: Food companies are jockeying for control of the booming health food industry, especially now that foods labeled as "non-GMO" are flying off store shelves, even though "organic" foods are held to a non-GMO standard as well as other stringent production standards.
