We already discussed that cows belch also accelerate global warming. And many sectors of livestock also contribute to carbon dioxide.
Below are the facts from the FAO: 1. Carbon emissions from making cattle feed a. Use of fossil fuels in the making of fertilizers accounts for 41 million tons of CO2 each year

b. Use of fossil fuels in the farm accounts for 90 million tons of CO2 per year (eg, diesel or LPG) c. Function over land used for livestock contributes 2.4 billion tons of CO2 per year, including here in the land converted to cattle sod, which changed the land to plant soya beans as cattle feed, or clearing land for livestock d. Carbon released from the processing of agricultural land for cattle feed (eg maize, wheat, or soybean) can reach 28 million per year of CO2. You need to know, at least 80% soybean harvest and 50% of the world's corn crops used as food ternak.7 e. Carbon released from the pasture into desert because terkikis contribute 100 million tons of CO2 per year

2. Carbon emissions from the animals digestive system a. Metana were released in the digestive process of animals can reach 86 million tons per year. b. Metana irrespective of the animal manure sewage can reach 18 million tons per year. 3. Carbon emissions from transportation and processing livestock meat to consumers a. CO2 emissions from the processing of meat can reach tens of million ton per year. b. CO2 emissions from transporting livestock products can reach more than 0.8 million tons per year. From the description above, you can see the scale of emissions of greenhouse gases produced from the livestock sector of each component. In Australia, greenhouse gas emissions from the livestock sector are greater than the power of coal. In the period of 20 years, Australia's farm sector accounts for 3 million tons metana each year (equivalent to 216 million tons of CO2), while the power sector coal accounted for 180 million tons of CO2 per year.

Years ago, investigators from the Ministry of Science Geophysics (Department of Geophysical Sciences) University of Chicago, Gidon Eshel and Pamela Martin, also disclose the relationship between food production and environmental problems. They measure the amount of greenhouse gases caused by red meat, fish, poultry, milk, and eggs, and compare that number with a berdiet vegan. They found that if the standard American diet to switch to diet plants, then will be able to prevent one and a half tons of greenhouse gas emissions ektra per person per year. Kontrasnya, switching from a standard sedan such as the Toyota Camry to a hybrid Toyota Prius saves about one ton CO2 emissions. * source wikipedia in Indonesia.
