With fatal food riots in poor nations, and with China rapidly approaching Western levels of consumption, we in the obese United States must redefine what constitutes, to borrow from McDonald's, a "happy meal." Scientists are concluding that along with more fuel-efficient cars and curbing industrial pollution, the simple act of eating less meat could help slow global warming.
"For the world's higher-income populations, greenhouse-gas emissions from meat eating warrant the same scrutiny as do those from driving and flying," according to the authors of a study last fall in the Lancet.
So eating meat, driving and flying "warrant scrutiny"? Be afraid. Be very afraid.
