Scientists are collecting cow farts and cow burps in plastic tanks to study the effects of the cow farts and cow burps, on global warming.
The Argentine researchers discovered methane from cows accounts for more than 30 per cent of the country's total greenhouse emissions.
[...]
Scientists are now carrying out trials of new diets designed to improve cows's digestion and hopefully reduce global warming. Silvia Valtorta, of the National Council of Scientific and Technical Investigations, said that by feeding cows clover and alfalfa instead of grain "you can reduce methane emissions by 25 percent".
Like I said, some things just have to be seen or in this case "smelled" to be believed.
Still waiting for Al Gore to comment.
