Meat turns up the heat as livestock emit greenhouse gases.

Studies by Carnegie institution shows that eating meat contributes to climate change, due to greenhouse gasses emitted by livestock. The research shows that livestock emissions are on the rise and that beef cattle are responsible for far more greenhouse gas emissions than other types of animals. The tasty hamburger has been fingered as a major culprit and It might be better for the environment if meat consumption is cut down. The effect of eating pork or chicken instead of beef has a much positive impact on environment . Carbon dioxide is the most-prevalent gas when it comes to climate change. It is released by vehicles, industry, and forest removal and also comprises the greatest portion of greenhouse gas . The methane and nitrous oxide are also greenhouse gasses and account for approximately 28 percent of global warming activity. Methane and nitrous oxide are released, in part, by livestock. Animals release methane as a result of microorganisms that are involved in their digestive processes and nitrous oxide from decomposing manure. These two gasses are responsible for a quarter of these non-carbon dioxide gas emissions and 9 percent of total greenhouse gas emissions overall. The researchers found a difference between livestock-related emissions in the developing world, which accounts for most of this increase, and that released by developed countries. This is expected to increase further going forward, as demand for meat, dairy products, and eggs is predicted by some scientists to double by 2050. By contrast, developed countries reached maximum livestock emissions in the 1970s and have been in decline since that time. Feeding manipulation and different management methods have demonstrated changes in levels of gas released.Cows fed on hay and pasture burp more due to ruminal activity on the feed thus releasing more methane than other cows on grains and corn where there is less emission.
