Calories, carbon dioxide could save lives
America’s obesity epidemic and global warming might not seem to have much in common. But public health experts suggest people can attack them both by cutting calories and carbon dioxide at the same time. How? They advise that people get out of their cars and walk or bike half an hour a day instead of driving. And also they suggest eating less red meat.
That’s how Americans can simultaneously save the planet and their health, say doctors and climate scientists. One numbers-crunching scientist calculates that if all Americans between 10 and 74 walked just half an hour a day instead of driving, they would cut the annual US emissions of carbon dioxide by 64 million tons.
