Asking Americans to give up their hamburgers, hot dogs, and Thanksgiving turkey might be a tall order. But I think there would be a fair number of people willing to try to cut down on their meat consumption if they thought it would be beneficial to the environment. The bigger obstacle may be the reputation of organizations, like PETA, who are touting the virtues of vegetarianism. To many, these groups have extreme views and perform media-grabbing stunts like tossing paint on fur coats (while people are wearing them) and offering to prepare faux "fried chicken" for Al Gore if he goes veggie.
However, the UN is held in high esteem by people around the globe. The last paragraph of that report includes suggestions for how to change the farming process that, along with lowered meat and dairy consumption, could work towards easing greenhouse gas emissions. If the connection between meat-eating and global warming were made more loudly by the UN, it would probably convince more people. For Alex Bruell's take, click here.
