If any of you remember Friday I was talking about how burping or the appearance of burping cows cause a lot of Greenhouse Gas Emissions and even though I was making it a little light story for Friday the more I read the more interesting it became!
As I read more I found out that 65% of the methane in the atmosphere is attributable to agriculture, with a significant portion arising from dairy cows. Methane is about 23 times more potent as a greenhouse gas than CO2.
Greenhouse gases, (water vapor, carbon dioxide, methane, nitrous oxide, and ozone), are components of the atmosphere that contribute to the greenhouse effect. Some greenhouse gases occur naturally in the atmosphere, while others result from human activities such as burning of fossil fuels such as coal.
The Greenhouse Effect is when sunlight reaches the surface of the Earth, some of it is absorbed and warms the Earth. Greenhouse gases naturally blanket the Earth and keep it about 33 degrees Celsius warmer than it would be without these gases in the atmosphere. This is know as global warming.
Methane is a colorless, odorless, flammable gas. Cows, sheep, goats, buffalo, termites, and camels produce & release methane naturally. When these animals burp, methane is released and in one day, a cow can emit ½ pound of methane into the air. Now multiply that by 1.3 billion cattle each burping methane several times per minute, I don’t have to tell you that is an incredible amount of methane released into the atmosphere every day!
In the UK the Department for the Environment, Food and Rural Affairs, (DEFRA), has begun a $1.5 million study examining how to curb methane emissions from cows, pigs and sheep.
They are not only trying to develop a new diet, as I mentioned Friday, but also investigating cows that are bred to live longer and thus reduce the number that are needed to produce the same amount of milk as before.
Sheep will be used in some studies because their digestive systems are similar to cows and they are considered more manageable.
As far as animal manure goes the project will look into breeding cows with more efficient stomachs, which then produce less waste. (Inventing a new cow and then cloning it, sort of)?
In Germany they are working on a pill which would trap more energy in the first of a cow’s four stomachs, thus cutting down on emissions.
In 2003, New Zealand went as far as proposing a “flatulence tax” on the large diary industry but was forced to back down because of a popular outcry. (How this is suppose to make the cows stop flatulating,(?), is way beyond me)!!
As you can see, in the past few years an international campaign has been waged against cow flatulence and how to solve the problem!
Whether or not any of these ideas will work…who knows, but certainly many different avenues are being investigated!
That’s all for me today, I hope to see you back again tomorrow for some more…
