Is it better for the planet than the cattle feed on the grass? Let’s see what the latest study says

Grass may be green for cattle feeding in the field instead of sebtareos, but Carbon emission They are not. A study published on Monday in the ‘National Science Academy’ concludes, even in the most confident hypotheses, the beef offered by grass does not create low carbon emissions Industrial beef.

Results in question of frequent encouragement of meat Beef As an environmental respectable option. However, some scientists confirm that other factors are imposed on other factors such as grass -fetched meat Animal welfare Or local environmental pollution, which complicates the choice of consciousness.

Is there a consumer about beef about beef?

“I think a large part of the population is really Purchase results reflect their values“Kidan Eshel, a professor of Environmental Physics at Bart College and one of the authors of the study.”

As for food, beef is so far, Something that causes excessive emission in climate change And one of the most resources and lands consuming. However, the demand for beef is expected to increase worldwide.

Land deforestation for cattle exploitation

And it is important to carefully weight the benefits of beef feeding with grass, because in most of the world that grows beef production, like South America, you Wilderness Richard Wait of the World Resources Organization said otherwise they would save carbon.

Experts say that the results of this study are meaningful because the production of grass feed is less effective than their industrial peers. Animals fed in the field They grow so slowly and don’t grow so muchSo there is more livestock to produce the same amount of meat.

Carbon storage is triggered by grass cattle?

Researchers used the number of emissions produced throughout Beef They then simulated many industrial cattle herds with grass. The amount of foods they consume, compared to the differences in size, Methane and carbon dioxide It is emitting and the amount of meat they produce.

These differences reflect real -life scenes; The cattle of the entire New Mexico and the livestock of a enthusiastic North Michigan have different entries and releases. Essel and his crew analyzed previous studies, which extent did they explore Livestock is favorable for grazing carbon savingsBut even in the best situations, they discovered that the amount of carbon that transmits pastures did not compensate for livestock emission.

The environmental impact of eating beef

Professor Randy Jackson, a lawn ecology of the University of Wisconsin-Matison University, who did not participate in the study, said that he had seen similar results in his own research, accordingly beef. Basto Fed has high emissions Assumed the same request. In fact, Ezal’s team quoted his work.

But he worrys that the study is more focused on reducing emissions, “without worrying about the environmental impacts beyond the GHG charge to the atmosphere.” The quality of the toothache and the soil And water, written in an email. The American Bullfet Association, a non -profit association that merges with livestock feed manufacturers, did not immediately pronounce the study.

We do not turn beef into a habit

Jennifer Schmid, reading Stability He believes that the Agricola D USA and the study at the University of Minnesota do not participate in the study, “It helps us be a little closer with the answer to the question of how much beef we should have on the horizon in front of plant proteins.”

According to Schmitt, if the amount of beef is reduced adequately and farmers can Devote more cultivated land to other foods In human consumption, the localized environmental benefits of grass feed can compensate for greater emission.

However, it can be difficult to convince Ishal. In his opinion, Climate change is “the second of world issues”So this should be a priority. “I am difficult to imagine a situation that is very sensible and beneficial to the environment to grow beef,” says Eshel. For consumers who want to be a vigilant about the environment, he added, “Don’t turn beef into a habit.”
