The Effects Of Animal Agriculture On The Environment Essay

Anna Lappé’s book, Diet for a Hot Planet, discusses the impact that meat consumption has on the planet and our environment. It discusses how the global food system is a major contributor to climate change, producing as much as one-third of greenhouse gas emissions. She writes about how the way we farm, what we eat, and how our food gets to our tables all

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

Animal agriculture is one of the largest contributors to climate change; however, this fact goes unacknowledged by most people. Livestock and their byproducts produce monstrous amounts

The Omnivore’s Dilemma, written by Michael Pollan, gives light to the question, “What should we have for dinner?” that he thinks Americans today cannot answer simply due to the fact that there are too many food options. This book serves as an eye-opener to challenge readers to be more aware and accountable of what is consumed daily. In order to understand fully where our food comes from, we must follow it back to the very beginning. Pollan goes on to discuss three different modern food chains in which we get our food: the industrial, the organic, and the hunter-gatherer. By tracing our food back to the beginning, we can understand that most of the nutritional and health problems America is going through today can be found on the farms that make our food and the government that can decide what happens. America deals with many food related illness such as, heart disease, obesity, and type II diabetes. Majority of a human and animals diet consists of being corn-fed leading to a high cause of obesity in the United States these are just some of the many diseases that come with over processed foods and diets we are unaware of. In this study, we will highlight the environmental and health issues and impacts related with modern agriculture and how these systems can be made more sustainable.

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

In my first year of college I have been introduced to copious amounts of new information and topics that had never crossed my mind. Becoming familiar with new ideas, food production and it’s impacts of the environment both locally and globally became of interest to me. I have been a vegetarian for about four years and as I have attended college I have learned more about the state of the issue with food production and sustainability. When presented with the list of books for our independent project Omnivore 's Dilemma immediately jumped at me. When Pollan stated in the introduction, “Farming and food industry produces even more greenhouse gases than all forms of transportation put together; the way you eat affects the world more than anything else you do,” I was hooked.

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

All across america, cows are confined to crowded, almost prison-like cells, with little to no regard to their health. They are forced to eat food that includes such ingredients like manure, cement, or even cow brains. This is one side of farming, but there is another. This farming has cows and other animals living how they would in nature, across rolling hills and bright green grasses. This is the essence of Local Sustainable farming. As defined in Michael Pollan’s award-winning commentary about the food we eat, The Omnivore’s Dilemma, the Local Sustainable Food Chain, one of four possible food chains, is characterized by not using pesticides, treating animals humanely, and sustainably creating healthier organic food. Out of Michael Pollan’s food chains, the Local Sustainable Food Chain is the best for America as it is much less harmful to the environment and lets animals live in their natural states.

Brought up in the southern of China, I often heard about that people from there “eat anything with four limbs except tables, anything that flies except aero planes, and anything that swims except ships”. Nevertheless, I eat more fruit, vegetables, nuts, and whole grains but less meat to make careful choices for environmental protection. Similarly, Kathy Freston argues that animal agriculture is one of the top contributors to global warming. In her Huffington Post selection “Vegetarian Is the New Prius,” Freston lists how many emissions of greenhouse gases people make when they eat meat and illustrates the consumption of tree in animal agriculture. She effectively convinces her audiences that the livestock results in the most serious environmental problems and encourages people to lead a greener diet to protect our environment. However, ardent craving, poor health, and perpetual hassle and cost prevent all Americans from being vegetarian.

The excess of greenhouse gases in our atmosphere have led to a dramatic rise in the climate and the hottest recorded years the Earth has seen. To be specific, “the 25 warmest years on record have come since 1980 [and] the 10 warmest since global recordkeeping began in 1880 have come since 1996, (p 56)” which is nothing to boast about, seeing as this is also the largest population and most technology the Earth has ever seen. Moreover, in lecture, we went over the amount of greenhouse gases created solely by livestock and how being a society dependent of livestock for food is very negative. Livestock emit about 68% of all agriculturally produced methane(lecture) and methane counts for approximately 18% of greenhouse gases (p 57). That is not to say that livestock do not create a large amount; in fact, human-caused methane emissions are almost solely from agriculture. To combat this, Dr. Wailes proposed that instead of basing our diet on water-heavy crops and methane-emitting animals, we switch to much more sustainable foods. One example of this would be to eat bugs. Bugs contain much more protein by the pound and do not eat alfalfa, which is what causes cows and other livestock to emit greenhouse gases into our atmosphere. Dr. Wailes also displayed a chart with three different “meals” which

Relevance: We all share the same planet, therefore, I believe it is vital to know the ways animal agriculture shapes our environment.

While all of us relatively understand how driving cars, leaving the lights on, or using too much water can affect the environment, there is one massive human activity that is frequently overlooked—eating. From growing, to processing, to distributing, and finally consuming, our agricultural system uses an immense portion of our planet’s limited resources and emits large amounts of greenhouse gases that have drastic effects on the environment. Because of this, it is imperative to understand the environmental impacts of the type of foods that we choose to include in our diets. While much of today’s population is heavily reliant on animal products, it is evident that a meat-based diet is not environmentally sustainable; on the other hand, a plant-based diet is much more environmentally friendly in terms of the amount of grain, water, and

Diets that focus on animal products, like meat, dairy, and eggs, require disproportionate high amounts of resources like water and land. Additionally, animals produce huge amounts of greenhouse gas emissions that are responsible for climate change. Such diets are not great for the environment that surrounds us, but more and more studies also link them to chronic diseases and early deaths. If the way we eat is bad for us and for the environment, we should inform ourselves about the potential impact of changing our diets.

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).

     Agriculture has changed dramatically, especially since the end of World War II. Food and fibre productivity rose due to new technologies, mechanization, increased chemical use, specialization and government policies that favoured maximizing production. These changes allowed fewer farmers with reduced labour demands to produce the majority of the food and fibre.
