Znastvenici istražuju smanjivanje kravljih plinova

Argentinski znanstvenici istražuju kako smanjiti emisiju štetnih plinova jer u zemlji s 55 milijuna krava čak 30 posto zagađenja dolazi upravo od goveda.

A lone cow grazing through lush green grass...it looks like a typical scene on Argentina's Pampas .

...except this cow is sporting a red tank on its back...with a tube leading to one of its four stomachs.

The bovine backpacker is part of a study designed to track and reduce the amount of the digestive gas methane that cows emit into the atmosphere.

With 55 million cows in Argentina, institute researcher Doctor Guillermo Berra says it's a stinky situation in more ways than one.

SOUNDBITE: Doctor Guillermo Berra, Argentina's National Institute of Agrarian Technology, saying (Spanish):

"Thirty percent of national emissions comes from emissions generated by cows."

The plan is to cut down on the contaminating gas by changing the animal's diet and lifestyle.

Still, even with all those cows...um, digesting...Argentina contributes only about half a percent of the world's total greenhouse gases.
