Can you provide a link supporting your claim that animal agriculture has >50% of the CO2 footprint or that the American continents produce much more CO2 than China?
I couldn't find the links for the second claim (its somewhere out there) but the ones provided don't account for animals, land use and rainforest elimination. All three are major factors of the animal agriculture.
Note that these links are talking about total greenhouse gas production, not just CO2 as was originally stated in pitchka's comment and questioned in mine. Pitchka's "18%/51%" estimates are not actually talking about literal CO2 output, but rather about general "GHG" (greenhouse gas) emissions, including gases like methane.
Based on these links which we traded, while you appear to be incorrect in your claims about literal CO2 emissions (which was what I originally commented on), perhaps what is more important is that you are correctly alluding to the effect of greenhouse gases besides CO2, such as methane.
The first claim seems to be incorrect at least based on simple googling to obtain the following link: https://www3.epa.gov/climatechange/ghgemissions/global.html
According to that link agriculture/land-use appears to have about 1/6 the impact of industrial processes/fossil fuel.
The second claim appears to be incorrect for "human produced" CO2 at least, using standard numbers. Perhaps there is another source?

Summing up the numbers there, I get the following results:
Annual CO2 Emissions:
(China): 10,540,000 kt
(USA + Canada + Mexico + Brazil + Argentina + Venezuala): 7,245,000 kt
