Scientists and farmers around the world are debating a very serious subject at the moment. Cow farts. Yes, really, they're talking about farting cows. They're talking about cow burps as well, and sheep burps, and even sheep farts.

Farts and burps are basically pockets of gas that get released from human and animal bodies.

This gassy mixture isn't useful, so our bodies push it out and away as best they can... in burps and farts. Got it so far? Hope you're not giggling by the way, this is very serious science.

One of the gases found in farts and burps is called 'methane'. A certain amount of methane in the atmosphere is natural, and is a good thing. Along with other so-called 'greenhouse gases' methane collects in the sky and traps warm air around our planet.

A scientific report published in California recently claimed that dairy cows in the area were producing almost 20 pounds (in weight, that's almost 10 kg) of gas every year, each. That's a huge, huge amount.

If that figure is accurate, it could mean that cow farts were causing more global warming than pollution from cars in that region, as millions of cows live there.

There’s an “Inconvenient Truth” for you.
