The Impact Of Animal Agriculture On The Environment

Better Essays
Register to read the introduction… If animal agriculture had this much of an impact over one hundred and seventy years ago, imagine the magnitude of impact it is having today. To provide land for the livestock, feed crops, slaughterhouses, and grazing fields, animal agriculture uses nearly seventeen million square miles of land. That’s about thirty percent of the earth’s land mass. Twenty-six percent of all ice-free land, seventy percent of all farming land, and thirty percent of all plant land surface is dedicated to animal agriculture. Vegetarian diets only require a portion of the thirty-three percent of farming land that animal agriculture uses, since one acre of plants can feed more humans than it can animals. Deforestation is a big result of animal agriculture since animals constantly need more food and areas to roam. Twenty-five million acres of rainforest in the Amazon was destroyed between 1996 and 2006, with nearly all of it going towards animal agriculture. Every minute over two-hundred sixty million acres of land are cleared for the purposes of animal agriculture. The land used then is degraded by overgrazing of livestock, compaction, and erosion from animal agriculture. The impact of animal agriculture on the environment is listed as one of the biggest sources of degradation which then decreases the amount of potential farming land. Worldwide twenty percent of pastures and seventy-three percent of dry pastures are degraded. Animal agriculture also uses large quantities of precious natural resources in addition to its massive land use. In the United States of America, it is estimated that one-third of all fossil fuels and raw materials are used for machinery and electricity in animal agriculture. There is a huge disparity between the cost of producing one pound of meat product versus …show more content…
Climate change, or global warming, is caused by trapped heat within our atmosphere by greenhouse gases. The three biggest greenhouse gases are carbon dioxide, methane, and nitrus oxide, which are all produced by animal agriculture. Carbon dioxide is one of the more common greenhouse gases, but methane is twenty times more powerful and nitrus oxide over three-hundred times more powerful. The United Nations have reported that animal agriculture is responsible for eighteen percent of all greenhouse gas emissions worldwide. Animal agriculture is the largest emitter of nitrous oxide, generating sixty-five percent of the world’s emissions. It is also the largest methane producer in America. When compared to veganism, the vegetarian practice of consuming no animal products at all, animal agriculture produces about seven times more greenhouse gases. Veganism has also been reported to save one-hundred and fifty percent as much carbon emissions as a Toyota Prius, one of the leading environmentally-friendly cars. A big percentage of animal greenhouse gases is produced from enteric fermentation, the scientific term for belching and farting. Waste from livestock also produces problems. Thirty percent of the greenhouse gases animal agriculture emits is from enteric fermentation and waste. The waste contains pathogens like E coli. The United States Department of Agriculture reports that livestock produce three times more waste than humans. For one pound of beef it requires forty-four pounds of livestock waste. All that waste pollutes, along with confined facilities, plowing, fertilizers, growth hormones, antibiotics, and pesticides. Animal agriculture uses fifty percent of antibiotics and thirty-seven percent of pesticide and in America. The Environmental Protection Agency reports that ninety-five percent of pesticide residue found in American diets comes from animal agriculture. Through greenhouse gases and

    A vegetarian diet take 3 times as much land which is 3/16 but to eat the way we do with meat,dairy and eggs it takes 18 times more land. This is because you can produce 37,000 lbs of vegetables on 1 1/2 acres, and only 375 lbs of meat on that same amount of land. If you switched to a complete vegan diet you could save 1100 gallons of water, 45lbs of grain, 30 sq. ft of forest, ten pounds of co2 and 1 animal’s life per…

    It’s time we phase out animal agriculture. Livestock alone uses nearly 50% of the United States mainland. There is such a high demand for meat that animal farmland has destroyed 80% of the Amazon rainforest. Annually, 160 million acres are cleared for the beef industry alone. We artificially bring life into this world only to end it at a tiny fraction of their natural life span, and use up major…

    James Owen writes in the National Geographic article, “40 percent of the Earth 's land is now given over to agriculture. “Raising animals for food requires massive amounts of land, food, energy and water. The byproducts of animal agriculture pollute our air and water systems. As the world’s appetite for meat increases, deforestation occurs to create pasture for animals and to grow crops to feed them. According to William Laurance of the Smithsonian Tropical Research Institute, forest destruction in Brazil between 1995 to 2000 was the “equivalent to seven football fields a minute.” This is a shocking statistic as the Amazon Rainforest is one of the planets most important carbon dioxide sinks.…

    Four-hundred and fourteen billion dollars are put towards the animal agriculture business today. While given the mindset that humans are omnivorous, a person who follows a vegan diet uses 1/11th oil, 1/13th water, 1/18th land, and produces fifty percent less carbon dioxide into the atmosphere. (Wilson, Lindsey. “The Carbon Footprint of 5 diets Compared.”) When making the switch to veganism, a person will save 1,100 gallon of water, forty-five pounds of grain, thirty square feet of land, twenty pounds of carbon dioxide, and one animal 's life per day. If the human population knew what was in the food that they were eating, they would think twice about putting it in their bodies.…

    The Amazon alone holds 20% of the world's oxygen. Cattle ranching is the biggest threat to the rainforests. Each cow has almost the size of a football field to graze. They leave some trees and bushes for shade. Brazil is the biggest meat exporter, so that's why they take so much land to keep up the demand.…

    “Research by Robert Goodland and Jeff Anhang, the authors of Livestock and Climate Change, indicates that raising animals for food produces 51 percent of global greenhouse gas emissions each year.” (Rajt) As you can see this amount is more than half of the amount of greenhouse gases. Climate change harms the planet we live and life it contains. So many animals are harmed because of climate change which is causing more and more animals to die off. By going vegetarian, we could reduce these emissions drastically. “Vast quantities of fresh produce grown in the US are left in the field to rot, fed to livestock or hauled directly from the field to landfill.” (Goldenberg) It is true that much of the produce grown is thrown away in landfills which can cause problems but food is the number one source of trash in landfills which includes meats as well.…

    Americans are the leading consumers of electricity per household. Today, a single household in America consumes 1.5 times as much as the French, 2.2 times as much as the Japanese, and 2.6 times as much as the German family (Before the Flood). These numbers are staggering when it takes into account how much coal it takes to power a single household in America and the amount of damage burning that coal has. Another factor in the production of carbon emissions into the atmosphere is the beef industry. Beef is the principal reason for deforestation in the current world, thousands of acres of forest are cut down daily to create grazing lands for cattle, this lowers the amount plant life to absorb carbon and fix back into organic matter.…

    Issues/Problem Identification Environmental Issues A purpose for housing animals in confined spaces in factory farming practices is so that less land is needed to handle and maintain animals. However, the mass production of animals for meat puts severe strain on natural resources such as land, water, and air, due to the amount of animal excrement that is produced by the large number of animals. Waste issues The EPA reports that “U.S. factory farms produce more than 500 million tons of manure every year…,” which is three times more than raw waste produced by Americans (The Humane Society of the United States, 2015). The concern is how the farms manage the large quantities of waste that is produced by the animals in such concentrated areas.…

    Most people don’t realize what we eat has such an impact on our Earth and the people in it. Two of the issues with livestock is that it takes 2,500 gallons of water and twelve pounds of grain to produce only one pound of beef. 80-90% of US water is used for agriculture and over half of the U.S. grain is being fed to livestock instead of being used for direct human consumption, and animal agriculture is one of the leading causes of world hunger. Animal agriculture is also responsible for 91% of amazon destruction and has an extremely negative impact on climate change. The documentary Cowspiracy says “Animal Agriculture is responsible for 18% of greenhouse gas emissions.…
