Global Warming researchers in Argentina are equipping cows with backpacks designed to trap the cows' methane emissions. Check out the link for an awesome cow pic...

Wild Facts:

With over 55 million cows, Argentina is among the top beef producers in the world.

The average cow produces 800-1000 liters of "emissions" PER DAY (mixed gasses, not just methane).

Methane is 23 times more effective than carbon dioxide at trapping heat in the atmosphere.

Initial results indicate that 30% of Argentina's green house gas production could be from cattle.
