Each time a cow lets out a burp, more methane gets added to the air. Researchers also say, these belches account for 3% of Britain's greenhouse gases, which in turn, adds to global warming. Now, scientists are exploring ways to deal with this latest environmental hazard -- "burping bovines."

Each cow emits 500 liters of methane a day; leaving researchers trying to figure out ways to reduce this gas-effect from Britain's two million cows.

A possible remedy would be to change food intake so that the cows consume more chewy foods. A change in diet would facilitate digestion and reduce gas. Other solutions include injections, microbes or maybe garlic extracts.

Nutrition expert, Professor David Beever tells the BBC, "It's like adjusting the carburetor."

As far as damage to the atmosphere is concerned, methane is 23 times stronger than carbon dioxide.
