We do not have a "companion earth" to test this against.
We have to get it right the first time.

Animal Industry contribution to Global Warming

Feedlot near Bakersfield, California, United States (36°19’N, 120°16’ W).

The USA produces and consumes the most beef in the world. This livestock farming brings together the Western regions of the United States specialized in reproduction and the great plains of the Midwest’s fattening regions where corn and soybeans are produced and where livestock farms called “feedlots” have been developed. The number of cattle herds in the world is now over one billion. Livestock farming has a disastrous effect on the environment and contributes to global warming more than the transport sector. This activity causes 65% of the hemioxide nitrate emissions, a gas which has 296 times more global warming potential than CO2, mainly because of manure. It also produces 37% methane emissions. Methane has 23 times more global warming potential than CO2. The 9% of carbon dioxide emissions are linked to human activities. But all around the world, the increase in standard of living comes with higher meat and dairy product consumption. World meat production should still increase 64% by 2050, going from 296 to 465 million tons.
