Answer :
Emissions are greatly decreased by raising cows more quickly. Because they generate more beef per animal and therefore less overall emissions, feedlot cows are often bigger than pasture-raised cows.
Methane emissions from greenhouse gases are most prevalent in beef. For every 3.5oz of protein consumed globally, 110lb (50kg) of greenhouse gases are released. Lamb has the second-highest environmental impact, yet its emissions are still 50% lower than those of beef. Around the world, one of the biggest causes of soil erosion is livestock raising. The significant loss of topsoil and organic matter that might result from converting forests into pasture, overgrazing, or exploiting marginal lands for feed production may require decades or centuries to replenish. both through changes in land usage and the agricultural production method. Scientists are investigating the sources of methane because of rising atmospheric amounts of the gas. 250–500 L of methane per day can be produced by ruminant animals. Methane emissions from ruminant livestock can be decreased by adding supplements or additives to feed. Methane is a gas that livestock normally create as a byproduct of digestion. Some feed additives have the ability to prevent certain rumen microbes from producing methane, hence lowering methane emissions. The annual methane gas production from a single cow ranges from 154 to 264 pounds.
