Dunno About This

Scientists are examining cow farts and burps in a novel bid to combat global warming.

Argentine scientists are strapping plastic tanks to the backs of cows

Experts said the slow digestive system of cows makes them a key producer of methane, a potent greenhouse gas that gets far less public attention than carbon dioxide.

In a bid to understand the impact of the wind produced by cows on global warming, scientists collected gas from their stomachs in plastic tanks attached to their backs.

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.

Guillermo Berra, a researcher at the National Institute of Agricultural Technology, said every cow produces between 8000 to 1,000 litres of emissions every day.

Methane, which is also released from landfills, coal mines and leaking gas pipes, is 23 times more effective at trapping heat in the atmosphere than carbon dioxide.

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".

JOKE: Three Young Native Americans

LOL

When the new school year started the history teacher was so excited because there were three little Indian boys in her class. She was beside herself with excitement. So she asks the first little Indian boy to stand up and tell the class what tribe he was from and how he knows this.

The little boy stands up and proudly throws out his chest & takes his fist and hits it on his chest. He says in a booming voice " I am a Cherokee. My Father and I walked for many moons and one day my Father says son, you see all this land. This is Cherokee land. So, I know I am a Cherokee."

The teacher says very good and asks the next little Indian boy to stand.
The little boy stands up and proudly throws out his chest & takes his fist and hits it on his chest. He says in a booming voice " I am a Comanche. My Father and I walked for many moons and one day my Father says son, you see all this land. This is Comanche land. So, I know I am a Comanche."

The teacher is growing more excited by the moment and asks the last little Indian boy to stand up.
The little boy stands up and proudly throws out his chest & takes his fist and hits it on his chest. He says in a booming voice " I am a Fuckawee".
The teacher looks dumb founded & says "I don't think there is any such tribe as the Fuckawee."

The little boy says, "My Father & I walked for many days and many nights, and many nights and many days. We ran out of water, but we kept walking. With no rest, we were getting weary. Finally, one day my Father stops and with his hand to shield the sun from his eyes, looks around.
"He said hummmm, where the Fuckawee"

JOKE: A little girl was out with her Grandmother

Photobucket

A little girl was out with her Grandmother when they came across a couple of dogs mating on the sidewalk.

"What are they doing, Grandma?" asked the little girl.

The grandmother was embarrassed, so she said, "The dog on top has hurt his paw, and the one underneath is carrying him to the doctor."

"They're just like people, aren't they Grandma?"

"How do you mean?" asked the Grandmother.

"Offer someone a helping hand," said the little girl, "...and they screw you everytime!"
