In addition to polluting ground and surface water, CAFOs also contribute to the reduction of air quality in areas surrounding industrial farms. Animal feeding operations produce several types of air emissions, including gaseous and particulate substances, and CAFOs produce even more emissions due to their size.

How are CAFOs bad for the environment?
CAFOs produce large amounts of greenhouse gas emissions that pollute the air and trap the sun's heat in our atmosphere. These gases are produced by degrading manure and the livestock's digestive processes. ... It is estimated that US livestock produces 3-20 times more manure than people in the US produce.
What are or might be some of the negative concerns with CAFOs?
Some of the negative concerns with CAFOs are that manure and wastewater from CAFOs have the potential to contribute pollutants such as nitrogen, phosphorus, organic matter, sediments, pathogens, heavy metals, hormones, antibiotics, and ammonia to the environment ("Animal feeding operations," 2013).
What are confined animal feeding operations and why are they controversial?
They are controversial because of the ethical issues over animal cruelty, and also because of the impact on human and animal health; unsanitary conditions brought about by the cramming of animals in close spaces offer a breeding ground for disease and bacteria, as well as the massive amount of biological waste that is ...
Why are CAFOs widely used and what are the major environmental problems associated with them?
Explanation: Concentrated animal feeding operations (CAFOs) are widely used because they lower costs. ... In terms of environmental problems, CAFOs produce a lot of animal waste that needs to be handled properly. Whereas human waste is treated, animal waste or manure is not.
What are the environmental impacts of concentrated animal feeding operations CAFOs )?
In addition to polluting ground and surface water, CAFOs also contribute to the reduction of air quality in areas surrounding industrial farms. Animal feeding operations produce several types of air emissions, including gaseous and particulate substances, and CAFOs produce even more emissions due to their size.
What is a disadvantage of a feedlot?
Disadvantage of feedlots is that cattle stand in small, crowded areas in their own feces and urine all the time. Another big concern and/or disadvantage of CAFO's is E. coli contamination. Cattle that are fed a high corn based diet can have increased amounts of E. coli in their digestive tract.
What is the major cause of pollution in CAFOs?
One of the main sources of CAFO-caused pollution in Michigan comes from discharges of manure and other wastes through the soil into field drainage tiles , which carry the wastes directly into county drains and streams.
What happens to the waste produced in a CAFO?
While human waste is treated in municipal sewer systems and subject to strict regulation, animal waste is stored in open ponds (called lagoons) or pits and is applied untreated as fertilizer to farm fields. ... Most lagoons are lined only with clay and can leak, allowing the waste to seep into groundwater.
What is meant by confined animal feeding operations?
The U.S. Environmental Protection Agency (EPA) defines AF. Os as agricultural enterprises where animals are kept and raised in confined situations. AFOs congregate animals, feed, manure and urine, dead animals, and production operations on a small land area.
How much pollution do animals produce?
Livestock and their byproducts account for at least 32,000 million tons of carbon dioxide (CO2) per year, or 51% of all worldwide greenhouse gas emissions.
How are animals treated in CAFOs?
CAFOs also increase the prevalence of antibiotic resistant diseases, due to the antibiotics regularly given to the animals. ... Concerns of this legislation included confinement standards, the treatment of nonambulatory animals, humane slaughter methods, the force-feeding of birds, and tail docking.
What is a CAFO and what are some of the environmental problems associated with CAFOs?
CAFOs are a major contributor to Harmful Algal Blooms (HABs) nationwide. HABs occur when an overgrowth of algae takes over a body of water and produce toxins that can threaten environmental and public health. So-called “nutrients” (phosphorous and nitrogen), major constituents of CAFO waste, fuel these algae outbreaks.
How are CAFOs regulated and permitted?
CAFOs are regulated by the federal Clean Water Act (CWA) under the National Pollution Discharge Elimination System (NPDES) permitting program2. ... State and local regulations vary5; some local governments have limited ability to enact regulations due to state preemption legislation6, 7.
What changes have occured in livestock production in recent years that have increased environmental problems?
A new report from FAO says livestock production contributes to the world's most pressing environmental problems, including global warming, land degradation, air and water pollution, and loss of biodiversity.
