Had It up to Here with Climate Change? Eat Beans Instead of Beef
A new study shows how one dietary change in the U.S. could make a 46%-plus dent in greenhouse gas reductions.
One of the most effective things Americans can do to curb greenhouse gas emissions is surprisingly simple: eat beans instead of beef.
A recent study showed that if every American made the switch, the U.S. could achieve between 46 and 74 percent of the reductions necessary to meet its emissions goals for 2020 that were pledged by former President Barack Obama. That considered, imagine the difference a reducetarian approach could have too, for those who can't go cold turkey—er, beefy—on their steaks.
“I think there’s genuinely a lack of awareness about how much impact this sort of change can have,” said study author Helen Harwatt to The Atlantic.
Climate change policy in the U.S. focuses mainly on reducing carbon dioxide (CO2) emissions by curbing or modifying energy production and usage. However, climate change is also driven by non-CO2 emissions — namely, methane (CH4) and nitrous oxide (N2O). More than half of these non-CO2 emissions come from livestock farming.
Globally, livestock farming accounts for 15 percent of human-caused greenhouse gas emissions. The effects, however, are disproportionately destructive: methane and nitrous oxide warm the planet significantly more than carbon dioxide.
The massive scale of livestock farming puts the problem into focus. According to the United Nations, one third of Earth’s arable land is used to grow feed for livestock, and in total, about a third of all land on the planet is used to produce animal products.
Feeding cows is also an especially inefficient process. During their lifetimes, cows will consume far more calories from food like beans than they’ll ever yield in meat. Growing that food takes up a lot of land. The study notes that the U.S. could free up 42 percent of its cropland if Americans gave up beef — that's more than the size of California.
Making the dietary switch would be an effective way for individuals to fight climate change without having to rely on lawmakers or private interests.
“The real beauty of this kind of thing is that climate impact doesn’t have to be policy-driven,” said Harwatt. “It can just be a positive, empowering thing for consumers to see that they can make a significant impact by doing something as simple as eating beans instead of beef.”
Obama pledged that U.S. greenhouse gas emissions would be roughly 17 percent lower in 2020 than they were in 2005. Making this dietary shift could be one of the easiest ways to reach that goal.
“Given the scale of greenhouse gas reductions needed to avoid the worst impacts of climate change, are we prepared to eat beef analogs that look and taste like beef, but have a much lower climate impact?” Harwatt asks. “It looks like we'll need to do this. The scale of the reductions in greenhouse gas emissions needed doesn't allow us the luxury of 'business as usual' eating patterns.”
Meteorologists propose a stunning new explanation for the mysterious events in the Bermuda Triangle.
One of life's great mysteries, the Bermuda Triangle might have finally found an explanation. This strange region, that lies in the North Atlantic Ocean between Bermuda, Miami and San Juan, Puerto Rico, has been the presumed cause of dozens and dozens of mind-boggling disappearances of ships and planes.
Nazi supporters held huge rallies and summer camps for kids throughout the United States in the 1930s.
- During the 1930s, thousands of Americans sympathized with the Nazis, holding huge rallies.
- The rallies were organized by the American German Bund, which wanted to spread Nazi ideology.
- Nazi supporters also organized summer camps for kids to teach them their values.

- A new study finds drinking large amounts of coffee and tea lowers the risk of death in some adults by nearly two thirds.
- This is the first study to suggest the known benefits of these drinks are additive.
- The findings are great, but only directly apply to certain people.
