Researchers in Argentina are currently studying the effect of methane produced by livestock on global warming, and to measure the amount of gas produced by cows, they outfitted the animals with pink tanks to collect their farts. No, I’m not kidding:

The Argentine researchers discovered methane from cows accounts for more than 30 per cent of the country’s total greenhouse emissions.

As one of the world’s biggest beef producers, Argentina has more than 55 million cows grazing in its famed Pampas grasslands.
