WATCH: Could selective breeding be the key to reduce methane emissions?

Every 90 seconds, a cow burps.

If you do the maths, that’s roughly 1,000 burps a day.

The Australian Bureau of Statistics says there were roughly 4.1 million cows in Victoria last year.

At this point you’re probably wondering why I’m making a video about cows and their burps.

So, when a cow digests food, microbes in its stomach make methane, which is what it expels when it burps. Or yes, when it farts.

And while methane doesn’t stay in the atmosphere as long as carbon dioxide, typically only 12 years compared to hundreds to thousands of years for carbon, it traps about 120 times more heat in a shorter amount of time. 

But selective breeding could be the solution.
