That article seems highly motivated to marginalize the effects of livestock. Quoting a section:
While methane is 28-times more heat-trapping than carbon dioxide, methane’s lifespan is just a decade, while CO2 — known as a long-life pollutant — remains in the atmosphere for 1000 years.
After ten years, methane is broken down in a process called hydroxyl oxidation into CO2, entering a carbon cycle which sees the gas absorbed by plants, converted into cellulose, and eaten by livestock.
In the first paragraph, it says methane isn't so bad because it lasts only 10 years, unlike CO2 which lasts 1000 years. In the very next paragraph it says the methane is broken down into CO2 which is then absorbed by plants and recycled. Wait, you just said it lasts 1000 years.
The next two paragraphs say that livestock accounts for 33% of the total methane released and blithely states that it all gets broken down and reused. If no additional animals are introduced, then net release equals net absorption. That is not very insightful -- eventually an equilibrium will be reached. This glosses over the real data that CO2 levels are rising, it is having measurable consequences, and is pushing control loops to new, worse states.
Citing one article written for the "Farm Business" trade publication isn't as conclusive as you seem to state.
