And now for something completely different – did you know that cow burps are a big source of methane emissions, almost as much as from wetlands and more than from rice paddies, landfills and biomass burning?
One single cow can produce up to one hundred liters of methane in one day, due to its slow digestive system.
The problem is so great that scientists in Argentina are studying it by strapping plastic tanks on the backs of cows to collect the methane gas. The tank is placed on the back of the cow and connected to the cow's stomach through a tube. Click here for a video of the cow with its tank.
I kid you not.
