This Is The #1 Cause of Human Induced Climate Change & Environmental Degradation & Nobody Knows About It
"In late November 2006, the U.N Food and Agriculture Organization issued a report stating that the livestock business generates more greenhouse gas emissions than all forms of transportation combined, and it’s true".(1)(2)(3)(4)]
Quote: “The billions of chickens, turkeys, pigs and cows who are raised for food each year in the U.S. produce a tremendous amount of excrement, releasing methane and other greenhouse gases into our atmosphere. Methane, which is at least 20 times more potent than carbon dioxide , accounts for 9 percent of the greenhouse-gas emissions in this country. And the 523 million chickens raised and killed each year in Delaware and Maryland alone generate enough waste to fill the dome of the U.S. Capitol about 50 times in a single year–or almost once a week. And each cow emits approximately 66 to 79 gallons of methane every single day. There are currently 88 million cattle in the United States. You do the math. Together, these cows reportedly produce more methane than landfills, natural gas leaks and fracking .”

Also this:
Historically(averaging over the past 400,000 years) CO2 is around 240ppmv, and now it is around 385ppmv(60% higher). Methane is historically(over past 1,000 years) around 700ppb and now at 1700ppb(140% higher). The % for CO2 is smaller if we start from the warm period average of around 280ppmv.
While the sheer volume of human released carbon dioxide and its warming affects probably are far greater than that of human released methane, humanity seems to have changed the concentration of atmospheric methane much more than that of carbon dioxide.
The fact is that changes in agriculture and diet are the easiest way for an individual to lesson his or her environmental impact. Local, organic, and vegetarian diets are a simple highly effective remediation strategy.
Disclosure: I am a vegetarian and so strongly biased on this particular issue, but this point cannot be ignored.

Methane intially reacts with ozone in a 'chain' reaction that ultimately produces CO2 and water vapour.
You could summarize the reactions into:
(3)CH4 + (4)O3 = (3)CO2 + (6)H2O
Oxidation of methane is the main source of water vapor in the upper stratosphere
