Cows and carbon emissions….

The simplicity is this namely....

1. Grass absorbs carbon (CO2) from the atmosphere.

2. Cows eat grass and belch, returning carbon to the atmosphere as methane (CH4).

3. As a greenhouse gas, methane is massively worse than CO2.

4. Methane survives a very short time, on a global warming timescale.

5. Methane rapidly breaks down and reverts back to the CO2 we started with.

Effect of a million cows on global warming?
NIL.
Effect on global warming of reducing the herd by a million cows?
NIL

More if you need it.
