I've read that the belching of methane by livestock contributes far more to atmospheric changes than does CO2.
Three links to relevant information about CO2 vs. methane:

Methane’s GWP [global warming potential] is 21 times higher than that of carbon dioxide:

While atmospheric concentrations of CO2 have risen by about 31% since pre-industrial times, methane concentrations have more than doubled. ...the primary sources of these [CO2] emissions—cars and power plants—also produce aerosols. Aerosols actually have a cooling effect on global temperatures, and the magnitude of this cooling approximately cancels out the warming effect of CO2.
