"Your personal impact on global warming may be influenced as much by what you eat as by what you drive.
That surprising conclusion comes from a couple of scientists who have taken an unusual look at the production of greenhouse gases from an angle that not many folks have even thought about. Gidon Eshel and Pamela Martin, assistant professors of geophysics at the University of Chicago, have found that our consumption of red meat may be as bad for the planet as it is for our bodies. "
Um, this is not news. Frances Moore Lappe pointed this out in "Diet for a Small Planet", first published in 1971. The amount of energy used in producing and "harvesting" beef is just insane.
Also from the article above:
"Energy used in agriculture has grown substantially in recent years, he says, and now stands at around 18 percent or 19 percent of the nation's energy use.
The researchers say their findings show that at least 6 percent of that use comes from the production of foods that are not energy efficient, like cattle and the food to feed them.
Considering that the "mean American diet is responsible for an additional ton-and-a-half of greenhouse gas emissions a year from each of us," the savings could be substantial."
