Article Summary of articles on Cows and Methane Gas Summary: Imagine a cow polluting our atmosphere all the time? It is a very real possibility. According to the article, “Methane emissions from cattle”, cows produce anywhere from 250 to 500 liters of Methane per day. Although they aren’t currently polluting as much as cars, that doesn’t mean they won’t eventually. Many might think that cows emit more methane gas from flatulence (or farting) but they actually emit more from belching. (1) This problem is an important issue around the world. In 2003 New Zealand even tried to put a tax on cow flatulence. In New Zealand cows and other livestock produce 34% of their greenhouse gasses. It is said that by 2030, the percentage of gas created by cows could be up by 60%. A cow is a type of animal called a ruminant. Ruminants eat their food and throw it up as cud. After they have thrown it up as cud they eat it again. Cows have four stomachs that they use for digestion and they digest similarly to humans. The stomach of a cow is filled with bacteria that helps them digest foods. Those bacteria also create massive amounts of methane. (1) Scientists are searching hard to find a way to stop or reduce the gases cows give out. The Carbon Farming Initiative even offers farmers money and other incentives if they feed their cattle a certain way. They want cows to be eating more tannins or oil. Tannins help lower the amount of methane significantly. Cows have an easier time with fiber
The author states that cows are responsible of at least 18% of methane that is in our atmosphere. Methane is a greenhouse gas that is odorless and colorless. The author also states that carbon dioxide is cleaner than methane. Methane released right into the atmosphere will be a thing of the past, because the National Institute For Agricultural Technology of Argentina has created a backpack that can be placed on cows. That bag has tubes that go into the digestive tract of the cow and collects 300 liters of methane. That is enough energy to be used to power a car for 24 hours instead of being released into the atmosphere. While each bag collects only 300 liters, one adult cow will produce 1000 liters of methane in one day. One day of methane collection can power a car for more than 72 hours or 3 cars for more than 24 hours. Methane can also be used for generating electricity by burning it to produce heat. While methane is harmful, there are still ways to reduce the output of it in the atmosphere by putting it to good
In the science article, “Beef and Climate Change Collide”, Los Angeles Times argues that beef is unhealthy for planet Earth due to the released gases that contribute to climate change. They claim that the U.S. beef production uses twenty eight times for land and eleven times more water than any other types of meets. Beef production pumps up five times more planet warming gases into our atmosphere than chicken, or pork. Furthermore, developing nations raising cattle have significantly increased the amounts of gases they produce. These developing countries have increased fifty one percent from 1961-2010. Although gases from cattle have been increasing, U.S. beef industry claims that the U.S. create the least amount of greenhouse gases being
Introduction (Attention Step): What do you think is the greatest cause of emission pollution? What do you believe is harming our planet? Well if you guessed that fossil fuel emissions are the biggest emission polluters, then you are completely wrong (attention getter). Animal Agriculture is actually the number one Greenhouse Gas emitter in the planet. Yes, cow farts are destroying the environment. It sounds crazy, but ever since the mid 60’s, agriculture associations have been spreading across the Americas and dominated the industry. The most destructive of all Ag corps are Livestock Corporation. These associations include IBP, Conagra, Perdue, Farmland National Beef, Cargill, etc … Animal Agriculture is effecting every single person in this room because we all breathe in the same air, drink the same water, and eat the same (credibility). The buildup of Animal Agriculture is a great destruction to our planet and our species because it is creating
One of the biggest controversies with livestock production is that the amount of greenhouse gas emissions that get released into the atmosphere. Its assumed that cars produce most if not all the greenhouse gas emissions however livestock has a big say in air pollution. According to Cassandra Brooks, writer for the Stanford Woods Institute for the Environment, 18 percent of all global greenhouse gas emissions are due to livestock production. This is nearly 20% and can be greatly reduced if people reduced their demand for meat. The Environmental Working Group used a tangible variable for Americans stating “if everyone in the U.S. ate no meat or cheese just one day a week, it would be like not driving 91 billion miles – or taking 7.6 million
It’s often argued that cows are the main source of our Methane emission, giving a strong argument to reduce, or even stop, our consumption of meat. In all actuality, only about six percent to seven percent of all greenhouse
Manufacture of meat - laden co2 and methane, and requires alot water. Farm animals such as cow or goats is the largest producer of methane. When they digest their food, the FAO of the UN mentioned the meat production accounts for 18 global warming, bigger than on the contributions of the entire world's
It won’t come as a surprise to anyone that Americans like their meat. In fact, America produced 93 billion pounds of meat and poultry in 2012, which included some 32 million cattle. As many of us already know, agriculture has a significant impact on our environment in a variety of ways. In order to successfully rear livestock, slaughterhouses require large quantities of water, and emit plenty of greenhouse gases – methane and CO2 specially – during production.
Have you ever thought of a cricket entering your mouth while asleep what if you were awake? Cow emissions are really bad for the environment. They use a lot of produce such as water and food. We waste most of the cow cause only 40% is edible. Eating bugs is a lot better for the environment, humans, and it can help stop global warming.
Attention getter: According to the Food and Agriculture Organization of the United States, animal agriculture is a leading source of carbon dioxide, nitrous oxide, and methane emissions, the top three greenhouse gasses (FAO, 2006).
Cows are herbivores, born to graze on grasses, clover, and whatever other delicious treats sprout from fertile fields. But grasses are neither rich in nutrients nor easy to digest. This is where the cow’s famous four stomachs and chewing the cud come into play. The physical breakdown of grasses by the teeth, followed by the bacterial breakdown in the rumen, eventually makes the nutrients available for absorption later down the line.
Where do happy cows actually come from? Most of our minds create an image of large fields where cows and other animals are free to roam and graze. In reality, however, most farms today are actually large corporate factories, not the vast fields and red barns that most Americans imagine. These consolidated operations known as CAFOs (Concentrated Animal Feeding Operations) are able to produce meats in high volume but have little to no regard for animal or human welfare, the environment, or food safety. CAFOs in the United States are able to produce and process these large amounts of meat year-round by providing sheltered farms for a range of livestock such as cattle, swine, and sheep. However, within these farms animals are
In addition to contaminating ground and surface water, CAFOs also make contributions to the reduction of air quality in regions surrounding commercial farms. Animal feeding operations produce many sorts of air emissions, with gaseous and particulate substances, and CAFOs produce even more emissions due to their size. The primary source of gaseous emissions is the decomposition of animal manure, while particulate materials are due to the movement of animals. The type, quantity, and rate of emissions created relys on what state the manure is in (solid, slurry, or liquid), and the way it is handled or contained after it is expelled. Occasionally manure is “stabilized” in anaerobic lagoons, which decreases volatile solids and controls smell before
“Methane has been identified as a significant contributor to global warming. It is second to carbon dioxide in contribution to global warming and is said to be 15-20% of all greenhouse gas emissions.” (Yusuf, Noor, Abba, A. Hassan, & Din., 2012, p. 1). The majority of the greenhouse gases emitted in the agricultural sector came from livestock (Yusuf et al., 2012, p. 2). Studies have shown that “cows produce more greenhouse gases than the entire
Cows are ruminants, a group of animals with a special adaptation that allows them to process the cellulose in grasses. This adaptation comes in the form of a “second stomach,” called a rumen where foliage goes to ruminant, or be broken down by the bacteria housed there. When rumination occurs it produces copious amounts of gas which is expelled through burping. Cows that are put on a corn based diet and are ingesting large amounts of starch and almost no roughage, have basically no activity in the rumen. This leads to a slimy build up causing gas to accumulate. The rumen expands and begins putting pressure on the lungs and can cause the animal to suffocate if the build up is not manually removed (Pollan 2006).
The impacts of livestock on global climate change are important to the health of the ecosystem because it causes the average global temperature to increase. Livestock contributes to the majority of methane emitted into the atmosphere because of the feces it produces. The growing population increase is not helpful to this matter because as a result, a demand of food arises. This demand for food also includes the demand for livestock because it is appropriate for the human diet. “Meat production is to double from 229 million tonnes in [2000] to 465 million tonnes in 2050” (McMichael et al. 1259). The methane emission rate is bound to increase because it is “dependent upon the population size of the [livestock], their productivity, and [handling system]” (Jose et al. 3).
