They target Methane for a reason, it’s produced naturally from various sources, at the surface, below surface and under water. Huge deposits of frozen Methane sit off the shore of California. When we sniff for gas leaks here in the oilfields of the Permian Basin and we sniff for Pentane and Ethane. If we sniffed for Methane our meters would be constantly going off due to naturally produced methane from the soil. Trying to blame cattle for this is a farce. Every living creature produces methane but nothing like the level produced naturally from the earth.
This is the composition of the average fart in humans.
Nitrogen: 20-90%
Hydrogen: 0-50% (flammable)
Carbon dioxide: 10-30%
Oxygen: 0-10%
Methane: 0-10% (flammable)
Which gas in that fart analysis is odiferous?
Looks like we are next.
