Greenhouse Gas Essay
The surface temperature of the earth is at a steady rise. The cause of this detrimental occurrence is attributed to the developing emission of greenhouse gases in the world’s atmosphere. Greenhouse gases (GAG) are the gases that trap heat in the atmosphere.
The four main gases that make up the GAG are carbon doodle, methane, nitrous oxide, and fluorinated gases. The largest reason for the rise of these gases Is the goings-on of human beings. The livestock Industry Is the largest of these actively.
An article In World Watch gained written by co-authors Goodling and Angina reports that livestock and its byproducts account for 32. 6 billion tons of carbon dioxide per year. This can also be figured as fifty-one percent of worldwide GAG emission.
The main sources of GAG from agriculture and livestock production are numerous. The deforestation of rainforest’s to grow feed for livestock is in constant rise. An estimated one and a half acres of rainforest’s is lost per second. The livestock industry’s growth has created a market of refrigerating and transporting the meat around the world.
The food sector is transport-intense; a lot of inputs to food production as well as food products themselves are transported in large volumes and sometimes long distances. This Is also a measurable source of GAG. Raising, processing and slaughtering the animal are ongoing contributors of GAG emissions. The methane from manure waste Is seven times more potent than carbon dioxide as a global warming gas. Animals including cattle, sheep, goats, pigs, horses and even poultry emit the methane gas through excretion after digestion.
In recent years methane gas from these ruminants is said to be of the world’s total production of Greenhouse gases. There are multiple factors that affect greenhouse gas emission as it pertains to the livestock industry. The feed level intake of the animal plays a part in greenhouse gas emission. The quality of the available forage plays a part in digestibility.
The process the feed itself goes through plays a part in the overall digestion and emission of the methane gas. Even the Individual animal’s genetics can affect the overall contribution the GAG In the atmosphere.
Lapels In the diet are a factor In GAG emission. The diet quality and efficiency goes along with digestibility, or passing of fed through the digestive tract. Stress levels of livestock Impact fed Intake and digestion. Feed intake determines nutrient concentration in the animal’s diet.
The Nutritional components such as carbohydrates, proteins and lipids in feedstuffs are broken down by microorganisms in the rumen and are converted into microbial cells. Rhea microbial cells include proteins and carbohydrates, and volatile fatty acids (Visas) and gases.
Volatile Fatty Acids are a major source energy for the cow. The amount each Volatile Fatty Acid produced is dependent on the diet. The diet fed to the animal contributes to the feed intake. A consistent ration of ingredients would help the diet.
Rhea feed intake can be affected by the environment’s temperature and humidity levels. Temperature can have an effect on the quality of the forage and its’ palatability. Microbial bacteria found in the rumen, called methanol’s, convert feed into a product that can be digested by the animal.
This process produces methane Inch is exhaled by the animal.
The growth and multiplication microbes depends on the rumens pH and the supply of energy and protein. The amount of methane produced by a ruminant can be compared to the greenhouse gas emissions of a car. Methane emissions from the digestion process in ruminant animals comprise 73% of the agriculture sector’s greenhouse gas emissions in New South Wales, Australia. Across Australia, ruminant animals alone contribute 13. 1% of Australia’s total national emissions.
Genetics in the animal can be of importance to the GAG mission as it affects the animal’s ability to produce quality goods.
Efficient animals require less feed than average. It is of great importance to select high producing animals, as this will reduce emissions/unit of product, referred to as emissions intensity. Efficient animals are already in all herds and flocks. Research must identify and remove inefficient individuals, while retaining and ensuring efficient ones.
The biggest benefits of reducing emissions and increasing production will be associated Ninth good animal management practice with efficient animals.
