Cow's burp reduce global warming.

This is absolutely bewildering-isn't it?

But you can't reprimand the cows that burp as bad manners.

Using modern plant-breeding methods to find new diets for cows that make them belch less is a way to reduce greenhouse gas emissions, scientists said on Monday.

The key is developing new varieties of food that are easier for cattle to digest and also provide a proper balance of fiber, protein and sugar, said Michael Abberton, a scientist at the UK-based Institute of Grassland and Environmental Research.

He noted the average dairy cow belches out about 100 to 200 liters of methane each day, making diet changes a key potential factor in reducing this greenhouse gas.

"There is a common misperception about how methane gets into the atmosphere," he said. "It is actually through belching rather than the other end."

We know that green houses gas is responsible for global warming.

Abberton said introducing easier-to-digest legumes that tend to reduce methane emissions is an example of an approach scientists are beginning to explore. Legumes such as clover and alfalfa are commonly used for animal fodder.
