Do cows produce more greenhouse gases than cars?

Cows contribute more to climate change in a year than cars do in the same amount of time. This is true, but that is because they each produce a different type of greenhouse gas. … Methane is a much more powerful and damaging greenhouse gas than carbon dioxide, although it stays in the atmosphere for less time.
