Why is animal agriculture bad for the environment?
Animal agriculture puts a heavy strain on many of the Earth’s finite land, water and energy resources. In order to accommodate the 70 billion animals raised annually for human consumption, a third of the planet’s ice-free land surface, as well as nearly sixteen percent of global freshwater, is devoted to growing livestock.
What is factory farming and how does it affect animals?
Animals that are bred into existence on factory farms are never allowed the chance to live a normal life. From the moment they are born, they are living in conditions that are unnatural in every sense of the word. The animals are fed diets that they would never consume in nature.
How is agriculture impacting the atmosphere?
Forests have fallen and grasslands trampled in favor of crops and pastureland. Now, however, this sector’s impacts are being felt in the atmosphere – carrying troubling implications for every living thing on the planet. The agriculture sector is one of the biggest drivers of anthropogenic – meaning human-caused – climate change.
What are the biggest sources of emissions from animal agriculture?
Cattle are by far the biggest source of emissions from animal agriculture, with one recent study showing that in an average American diet, beef consumption creates 1,984 pounds of CO2e annually. Replacing beef with plants would reduce that figure 96 percent, bringing it down to just 73 pounds of CO2e.
How animal agriculture affects our planet?
Animal agriculture produces 65% of the world’s nitrous oxide emissions which has a global warming impact 296 times greater than carbon dioxide. Raising livestock for human consumption generates nearly 15% of total global greenhouse gas emissions, which is greater than all the transportation emissions combined.
How does animal production affect the environment?
Livestock emit almost 64% of total ammonia emissions, contributing significantly to acid rain and to acidification of ecosystems. Livestock are also a highly significant source of methane emissions, contributing 35–40% of methane emissions worldwide.
Is animal agriculture harmful to the environment?
Although often overlooked in conversations about climate change, animal agriculture is a major driver of global warming and biodiversity loss. As we will see below, the industry destroys ecosystems, releases huge quantities of greenhouse gases, wastes vast amounts of water, and is a major source of pollutants.
How does agriculture impact the environment?
Agriculture is the leading source of pollution in many countries. Pesticides, fertilizers and other toxic farm chemicals can poison fresh water, marine ecosystems, air and soil. They also can remain in the environment for generations.
How does animal agriculture help the environment?
Livestock production can be an important component of a sustainable agricultural system because it can provide an quality source of plant nutrients, be an income generator, and provide a an environmentally sound use of certain lands.

Meat consumption is responsible for releasing greenhouse gases such as methane, CO2, and nitrous oxide. These gases contribute to climate change, such as global warming. Livestock farming contributes to these greenhouse gases in several ways: The destruction of forest ecosystems.
What are the environmental factors that affect agriculture?
Environmental factors that influence the extent of crop agriculture are terrain, climate, soil properties, and soil water. It is the combination of these four factors that allow specific crops to be grown in certain areas.
How does agriculture affect global warming?
Agriculture is a major part of the climate problem. It currently generates 19–29% of total greenhouse gas (GHG) emissions. Without action, that percentage could rise substantially as other sectors reduce their emissions. Additionally, 1/3 of food produced globally is either lost or wasted.
How does agriculture affect biodiversity?
Biodiversity generally decreases when the intensity of farming increases11. Farming has become ever more industrial, and farmers are tending to specialise, focusing on a few or even single high-output species or varieties.
How much carbon dioxide is wasted in the world?
Moreover, approximately one gigaton of carbon dioxide equivalent worth of animal-based foods is wasted globally every year. If global consumption of meat and dairy continues to grow at the current pace, the agriculture sector could consume about 70 percent of the allowable budget for all GHG emissions by mid-century.
What is the biggest contributor to global water pollution?
Furthermore, air and water pollution can be directly attributed to the livestock sector, which is the largest contributor to global water pollution. The livestock sector is also one of the leading drivers of global deforestation, and is linked to 75 percent of historic deforestation in the Brazilian Amazon rainforest.
How does animal agriculture affect the Earth?
Animal agriculture puts a heavy strain on many of the Earth’s finite land, water and energy resources. In order to accommodate the 70 billion animals raised annually for human consumption, a third of the planet’s ice-free land surface, as well as nearly sixteen percent of global freshwater, is devoted to growing livestock. Furthermore, a third of worldwide grain production is used to feed livestock. By 2050, consumption of meat and dairy products is expected to rise 76 and 64 percent respectively, which will increase the resource burden from the industry. Cattle are by far the biggest source of emissions from animal agriculture, with one recent study showing that in an average American diet, beef consumption creates 1,984 pounds of CO2e annually. Replacing beef with plants would reduce that figure 96 percent, bringing it down to just 73 pounds of CO2e.

As we will see below, the industry destroys ecosystems, releases huge quantities of greenhouse gases, wastes vast amounts of water, and is a major source of pollutants.
How Much Land Is Used for Animal Agriculture?
Unsurprisingly, raising more than 70 billion land animals to kill each year for food requires vast areas of farmland. Although most of these animals are denied the opportunity to graze and are given so little space that they can barely turn around, arable land is needed to grow crops for them to eat.
Is Animal Agriculture Bad for Human Health?
Animal agriculture poses a number of serious threats to human health. Antibiotic resistance, which, as we have seen, is accelerated by the livestock industry’s abusive use of medication, already kills 35,000 people in the U.S. each year.
Conclusion
The environmental destruction caused by animal agriculture far outweighs any benefits, especially for those who live in developed nations with access to a wide variety of foods. With so many plant-based options available, there is no need to farm animals on such a massive scale.
Why do multinationals have complete control over their own production?
And because they are able to contract the dwindling number of farms to produce animal products their way , they have complete control.
How has animal agriculture made it possible for food corporations to turn farms into efficient factories?
The advent of industrial animal agriculture has made it possible for food corporations to turn farms into efficient factories, by doing so, disregarding the fact that they are dealing with sentient beings and forcing them to endure a lifetime of suffering and cruelty.
Why don’t humans need animals?
Humans don’t need to consume animals in order to be healthy and survive. And we certainly don’t need to treat animals like machinery or commodities. Industrial animal agriculture is responsible for the suffering and slaughter of trillions of animals each and every year around the globe. It is responsible for the degradation …
How does factory farming maximize profits?
Factory farming, from a business perspective, is a brilliant way to maximize profits by dramatically increasing the supply while at the same time bringing down production costs. And if factory farming was dealing with the production of cotton T-shirts or toys then it wouldn’t be as objectionable as it is.
What is factory farming?
Factory farming is the answer corporations found when the question was about turning animal agriculture into an industrial operation.
What would happen if people cared about animals?
If they care about animals, they wouldn’t breed them into existence for imminent slaughter in the first place.
Why do farmers treat animals the same as workers treat equipment or machinery in a factory?
By treating farm animals the same as workers treat equipment or machinery in a factory, farmers are able to raise and produce animals at extraordinary rates. Doing so makes it final product, clothing or food in most cases, significantly cheaper for the consumer.
How much carbon dioxide is produced by livestock?
Farmed animals – referred to as livestock – generate over 14 percent of all anthropogenic emissions, with estimated totals hovering around seven gigatonnes of carbon dioxide emitted every year. The bulk of these emissions are due to raising cattle for meat and dairy, contributing 60 percent of total livestock emissions. These emissions are thanks to the vast amounts of resources cows consume, the land they require for pasture (in the case of beef cattle), and other manure they produce. Cow manure contains nitrous oxide and methane, the latter being one of the most potent greenhouse gasses due to its outsized ability to absorb heat.
What gases are used to absorb heat?
Certain gases are more effective at absorbing heat than others; these include methane, nitrous oxide, and perhaps the most infamous, carbon dioxide. These three gasses are among the main culprits of climatic warming and change caused by human activities.
How much carbon dioxide is in a ton of nitrous oxide?
For example, one ton of nitrous oxide – emitted by agricultural processes including the use of nitrogen fertilizers in crop production – is equivalent to nearly 300 tons of carbon dioxide.
Why is agriculture the gravest mistake in the world?
Unless greenhouse gas emissions are seriously curbed, the world is going to be a far more difficult place to endure.
How much more potent is methane than carbon dioxide?
Methane is approximately 30 times more potent in its ability to absorb and trap heat in the atmosphere than carbon dioxide.
What are the environmental effects of monocrops?
Vast fields of monocrops also cause a host of environmental effects, including air pollution. Pesticides and herbicides are sprayed in liberal amounts, which can cause a host of debilitating illnesses, including cancers, for farmworkers and surrounding communities. Soil depletion is also a serious looming issue.
What percent of the world’s land is used for agriculture?
Land Use. A full 50 percent of the world’s livable land – meaning land that is ice-free and fertile – is being used for agriculture. No other human activity takes up more space. In contrast, all urban areas account for around one percent of livable land use.
Why does the EPA quote direct emissions?
The EPA quotes direct emissions for all sectors in order to quantify emissions from various sectors on a level playing field, as not every sector has completed Life Cycle Analyses regarding their emissions. In other words, using direct emissions when comparing other sectors is an apples-to-apples comparison, though it is not the most thorough.
How much does livestock contribute to the world’s emissions?
