New research shows that at pounds of pounds, grazing cows produce at least as much hot closed gas as those grown in feedlots.
studyIt is published in Proceedings of the National Academy of Sciencesmodelling the emissions from grazing and fattening cows in the United States, finding that even in the best scenarios, grazing cows are superior to industrial counterparts.
This is because grazing cows grow more slowly and have less meat. To produce the same amount of beef as feedlot operations, ranchers need to raise more cows over the long term.
Grass may reduce some emissions, but it is too little absorbed to offset the effects of grazing. The study found that grass-fed beef emissions were 25% higher than feedlot beef and several times higher than eggs, milk, beans and nuts.
Some experts say In contrast to feedlots, raising cattle in the fields is more humane. Grazing cattle also produce less contamination than industrial cattle. It is produced in Fertilizers and pesticides to wash in rivers and lakes.
The best option is to simply avoid eating beef, according to Gidon Eshel, the lead author of Bard College. Talk to Associated PressEchel said, “Don’t make beef a habit” for diners who are trying to minimize the impact on the climate.
