Climate change is a big problem, and in order to minimize its effects, big countries like the United States will have to dramatically reduce their greenhouse gas emissions. The common way to tackle this goal is to impose strict regulations on vehicle emissions and to increase renewable energy sources, but new research suggests there may be a cheaper—but probably not easier—way: replace beef with beans.
A group of researchers analyzed our food habits and the amount of greenhouse gases that are emitted when that food is produced and found that if Americans replaced all their beef with beans we would be for 2020.
That's easier said than done, though. The meat production industry is huge and employs thousands of people. Not to mention that many Americans would be reluctant to give up meat, even if it meant helping to save the planet. It's probably not necessary to give up meat entirely; even a small reduction in the amount of meat we eat per week would dramatically reduce greenhouse gas emissions.
So maybe think twice before eating that burger.
