It's hard to ignore the evidence mounting against factory-farmed meat: Raising livestock for food is one of the largest contributors to global warming, accounting for 20 percent of man-made greenhouse gases emitted each year. If all Americans skipped their daily eight ounces of meat one day per week, we could save more emissions over the course of a year than if we gave up traveling by cars, trains, planes, and ships combined.
There are the health benefits to eating less meat, as well. People who consume a plant-based diet weigh less, have lower incidence of heart disease, diabetes, and many cancers, and on average live longer than meat eaters.
So why aren't we all vegetarians? Are we really that attached to meat?
