That\u2019s possible because cattle have a multichambered stomach where microbes ferment grass and other tough fibrous vegetation, making it digestible.<\/p>\n<p class=\"css-158dogj evys1bk0\">\u201cThe way I look at it, I\u2019ve got 46,000 fermentation vats going out there,\u201d Mr. Shields said.<\/p>\n<p class=\"css-158dogj evys1bk0\">But this process, called enteric fermentation, also produces methane, a potent planet-warming gas that the cattle mostly belch into the air. And with about 95 million cattle in the United States, including more than 25 million that are fattened for slaughter each year at feedlots, the methane adds up.<\/p>\n<p class=\"css-158dogj evys1bk0\">Researchers within and outside the industry are working on ways to reduce emissions from fermentation, through feed supplements or dietary changes. Other efforts aim to lower emissions from the animals\u2019 waste \u2014 a source of methane as well as another powerful greenhouse gas, nitrous oxide \u2014 through improved manure storage and handling.<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"><\/aside>\n<\/div>\n<div class=\"css-1fanzo5 StoryBodyCompanionColumn\">\n<div class=\"css-53u6y8\">\n<p class=\"css-158dogj evys1bk0\">In the United States, cattle are far from the largest source of greenhouse gases, which include carbon dioxide, methane and others. Their total contribution is dwarfed by the burning of fossil fuels for electricity, transportation and industry. But livestock are among the largest sources of methane, which can have 80 times the heat-trapping power of carbon dioxide although it persists for less time.<\/p>\n<p class=\"css-158dogj evys1bk0\">Estimates vary, in part because animal emissions are more difficult to quantify than, say, flue gases at a power plant.

fossil-fuel burning, which adds to warming by putting ancient carbon back into the atmosphere as carbon dioxide \u2014 where it traps the sun\u2019s heat \u2014 cattle methane is part of a relatively short cycle. The methane results from eating vegetation that has grown by taking carbon dioxide from the atmosphere. After about a decade, the methane breaks down, forming carbon dioxide, which is used for more plant growth.<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"><\/aside>\n<\/div>\n<div class=\"css-1fanzo5 StoryBodyCompanionColumn\">\n<div class=\"css-53u6y8\">\n<p class=\"css-158dogj evys1bk0\">In effect, the animals are recycling carbon over a short time frame, so if the cattle population remains roughly the same, the contribution to warming remains about the same. \u201cIt\u2019s leaving the atmosphere as fast as it\u2019s coming,\u201d said Alan Rotz, a researcher with the U.S. Department of Agriculture who has studied emissions from beef production.<\/p>\n<p class=\"css-158dogj evys1bk0\">The beef industry points out that, rather than remaining the same or increasing, the overall cattle population in the United States has declined by more than 25 percent since peaking in the 1970s, mostly because of efficiency improvements. But cattle populations are growing overseas, as nations become more affluent and beef consumption increases.<\/p>\n<p class=\"css-158dogj evys1bk0\">\u201cFor the U.S., we\u2019re probably not adding methane to the atmosphere\u201d from livestock, Dr. Rotz said. \u201cBut you add more methane as you add more animals, as we are doing globally.\u201d<\/p>\n<p class=\"css-158dogj evys1bk0\">And even in the United States, with overall greenhouse gas emissions that are second only to China, making a dent in cattle emissions would have an effect.<\/p>\n<p class=\"css-158dogj evys1bk0\">Cargill Corporation, the food and agriculture giant that supplies feed to the beef industry, feedlots and others, is one of many companies doing research on substances that could be added to reduce methane emissions, said Heather Tansey, a director of sustainability at the company.<\/p>\n<p class=\"css-158dogj evys1bk0\">Cactus Feeders, which moves 1.1 million cattle a year through its 10 feedlots, designates about one-quarter of its pens at the Wrangler lot for studies on topics including the effects of dietary changes and ways to cut emissions from manure.<\/p>\n<\/div>\n<\/div>\n<div

\/><\/picture>Jim Friemel, who with his wife, Melanie, owns and runs an independent feedlot in Hereford, Texas, that is half the size of Wrangler, doesn\u2019t devote space to research. But he\u2019s heard about melting ice sheets, rising sea levels and other accelerating effects of climate change, and would feed his 20,000 head of cattle a dietary supplement to reduce methane emissions if one were available at reasonable cost.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"css-1fanzo5 StoryBodyCompanionColumn\">\n<div class=\"css-53u6y8\">\n<p class=\"css-158dogj evys1bk0\">\u201cSure, I\u2019d use it,\u201d Mr. Friemel said, \u201cif it would help stop the ice from melting.\u201d<\/p>\n<p class=\"css-158dogj evys1bk0\">The emissions efforts are part of a broader push to make beef production more sustainable, including issues of water and land use. The work has taken on more urgency as the industry has come under pressure from environmentalists and others who say that to help conserve resources, the world must eat less meat.<\/p>\n<p class=\"css-158dogj evys1bk0\">In a report last year, for example, <a href=\"https:\/\/www.thelancet.com\/journals\/lancet\/article\/PIIS0140-6736(18)31788-4\/fulltext?utm_campaign=tleat19&amp;utm_source=hub_page\" class=\"css-1g7m0tk\" title=\"\"  target=\"_blank\" rel=\"noopener noreferrer\">the EAT-Lancet Commission,<\/a> an international group of scientists, recommended a 50 percent reduction in global consumption of red meat and some other foods by 2050.<\/p>\n<\/div>\n<aside class=\"css-ew4tgv\" aria-label=\"companion column\"><\/aside>\n<\/div>\n<div class=\"css-1fanzo5 StoryBodyCompanionColumn\">\n<div class=\"css-53u6y8\">\n<p class=\"css-158dogj evys1bk0\">In the United States, emissions have been affected by a major dietary change introduced decades ago. Feedlot cattle eat a diet in which corn or other high-energy grains account for up to about half the feed. This, plus reduced movement in the pens, helps the cattle fatten, producing the kind of well-marbled beef that consumers like. Studies have shown that a high-grain diet produces less methane.<\/p>\n<p class=\"css-158dogj evys1bk0\">But the microbes that break down corn are different from those that work on grass, so cattle have to be monitored carefully for bloat or other health problems. And farming of corn uses a lot of water, adding to concerns about resources.<\/p>\n<\/div>\n<\/div>\n<section class=\"meteredContent css-1r7ky0e\">\n<div class=\"css-1fanzo5 StoryBodyCompanionColumn\">\n<div class=\"css-53u6y8\">\n<p><a target=\"_blank\" href=\"https:\/\/www.nytimes.com\/2020\/10\/21\/climate\/beef-cattle-methane.html\" >TO CONTINUE READING Go to Original &#8211; nytimes.com<\/a><\/p>\n<\/div>\n<p>_____________________________________________<\/p>\n<p style=\"padding-left: 40px;\"><em>Henry Fountain specializes in the science of climate change and its impacts.
