Nearly all farm animals — 99 percent — are raised on one of the 20,000 factory farms located in the United States. That includes an estimated 42 million cows that go through the factory farm system every single year. These “factory farms” or “CAFO”s (Concentrated Animal Feeding Operations) are minimally regulated due to ag-gag laws, which has led to a whole host of health and environmental problems. Sadly, this contamination of our air is destroying our planet and making us sick.

1. Animal Waste Causes Harmful Air Pollution

Animal farms may produce food, but they also produce massive amounts of animal waste like urine and manure that emit around 400 different harmful gases into the atmosphere. Some of these gases include nitrous oxide, ammonia, particulate matter, endotoxins, and hydrogen sulfide. Because thousands of animals are kept together in factory farms, the concentration of the gases produced can be extremely dangerous to the local community. For example, roughly 80 percent of ammonia emissions in the U.S. comes from animal waste.

Additionally, when factory farm waste decomposes, it releases airborne particulate matter along with the harmful gases. These particulates can include dry manure, feathers, bits of feed, and animal dander. They can travel through the air for miles and turn the sky hazy near the factory farm. The antibiotics that livestock are given to protect them while living in a high stress, filthy environment are also potent airborne matter.

In one experiment, researchers from Texas Tech placed air samplers 10 to 30 yards both upwind and downwind from beef and dairy feedlots throughout the fall and winter months. A stunning 100 percent of the samples tested positive for Monenisin, an antibiotic that is commonly used in human medicine. While this antibiotic is not thought to contribute to a surge antibiotic resistant bacteria; tetracycline antibiotics, that do contribute to bacteria resistance, were found in 60 percent of the downwind samples and 30 percent of the upwind. Tetracycline antibiotics are used to treat pink eye and urinary tract infections, both of which are becoming more difficult to treat as bacteria develop resistance.

2. Animal Agriculture Releases Almost One-Fifth Of The World’s Greenhouse Gas Emissions

The United Nations Food and Agriculture Organization (FAO) estimates that livestock production is responsible for 14.5 percent of global greenhouse gas emissions, while other organizations like the Worldwatch Institute have estimated it could be as much as 51 percent. Even in the more modest estimate, this is more than all the cars, trucks, planes, and ships in the world!

One reason for this is that more than a third of all raw materials and fossil fuels consumed in the U.S. are used in animal production. Specifically, livestock accounts for an estimated nine percent of global carbon dioxide emissions, 35 to 40 percent of global methane emissions, and 65 percent of nitrous oxide emissions.

In fact, methane gas is one of the largest contributors to global warming and can trap up to 100 times more heat in the atmosphere than carbon dioxide over a five-year period. Most of the methane comes from cows on factory farms that are fed low-quality grains that their bodies were not made to digest, resulting in high levels of indigestion and flatulence. All of this gas then enters our atmosphere.

In addition, meat and other animal products have a huge carbon footprint due to the deforestation needed to grow feed and graze animals, as well as all the transportation involved in both feeding the animals and distributing the products to consumers. That ends up being a lot of travel and tons of carbon output.

3. Factory Farms Produce An Unbearable Smell For Local Residents

Living by an animal farm can be quite uncomfortable. Livestock in the U.S. produce 500 million tons of excrement every year. This is way more waste than factory farms could ever redistribute as fertilizer, so the majority of waste is left to fester in massive, open-air waste lagoons. When these cesspools get full, factory farms will frequently get around water pollution limits by spraying liquid manure into the air, creating mists of pollutants carried away by the wind.

Having to live with the awful smell and harmful gases released by farm waste can ruin people’s health and quality of life. The CDC has even reported that mental health deterioration and increased sensitization to smells can occur in people who live near factory farms. Sadly, many communities located near factory farms fall below the poverty level so they do not have the option to relocate to a place with cleaner air.

4. Animal Agriculture Increases Acid Rain

Another problem with the animal waste collecting in the massive lagoons is that the waste breaks down and forms ammonia gas. This then breeds bacteria, which combines with other pollutants in the air to form nitric acid. The nitric acid builds up in the atmosphere and then returns to the surface of the earth as acid rain, harming soil, forest habitats, and water ecosystems.

5. Animal Agriculture Causes Several Serious Health Concerns

Given all of this air pollution, it is not surprising that animal farming causes several serious health problems for farm workers and local residents. People tend to suffer from respiratory irritation, bronchitis, lung inflammation, dust toxic syndrome, asthma, and possibly cardiac arrest. Ammonia emissions can cause a variety of harmful health effects like dizziness, eye irritation, respiratory illness, and nausea. Releases of dangerous levels of hydrogen sulfide can cause sore throats, seizures, comas, and even death.

Asthma can be a real concern, especially for children living near these farms. According to the Centers for Disease Control (CDC), children raised in communities near factory farms are more likely to develop asthma or bronchitis.

Finally, the unsanitary conditions on factory farms, poor quality of animal feed, and overuse of antibiotics in livestock have resulted in diseases that are not always easy to manage. Swine Flu and Avian Flu, for example, can be distributed through the air, causing local residents to get sick.

What You Can Do

They say once you know truth, it’s your job to spread it. So in this case, it is up to you to share this article and educate others about the dangers of animal agriculture air pollution – and to look to solutions. The best way to lower the amount of air pollution caused by animal agriculture is to go to the source. If we all take action to lower our consumption of meat and dairy, we can help lessen the demand for these products and slowly stymie the industry.  By simply choosing more plant-based foods, you can effectively halve your personal carbon footprint and help mitigate some of the other negative impacts imbued by animal agriculture.

Sorry but I will argue! The author writes that "Most of the methane comes from cows on factory farms that are fed low-quality grains that their bodies were not made to digest, resulting in high levels of indigestion and flatulence". I fact, most studies show that grass-fed cows, and generally cattle kept in more extensive (rather than intensive) production units, produce more rather than less methane per animal. I am certainly not advocating factory farming, but in terms of the methane exhaled by cows, extensive farming tends to be much worse, even when you take into account the emissions produced from the feed. Firstly, what the author calls \'flatulence\' - methane exhalation - is a totally natural and healthy process for ruminants. So in fact a diet of grain - poor or high quality - reduces this process (i.e. less methane is produced), which for cattle is not healthy - though it\'s better for the climate. Secondly, factory farming is designed to fatten the animals (or make them produce milk) in the fastest possible way. It\'s terrible for the animals and generally for the environment, but in terms of the methane produced it\'s actually better for the climate. Thirdly, factory farming overall tends to require a lot less land per animal - which in turn tends to translate into less emissions. Grass-fed cows require a lot of grazing land, which could otherwise be reforested and thus store carbon. Finally, on CAFOs there is the possibility of using cattle manure to create fuel via a biodigester - which is not possible (or much harder to do) in the case of grass-fed production. Again, I am in no way saying that CAFOs are a good idea - far from it - just stressing the fact that grass-fed cattle - beef and/or dairy - is equally bad - better for the animals but worse overall for the climate. If you do more research you will find evidence of this.
Thus in \'Livestock\'s Long Shadow\' the FAO writes that “The principal means of limiting livestock’s impact on the environment must be intensification”.
For instance, the Centre for Biological Diversity writes that \'While “grass-fed” beef is arguably more humane for the livestock animals and doesn’t produce the concentrated manure and runoff found at factory farms, it isn’t as sustainable for wildlife or the planet as many people believe, especially in the context of a human population of billions that needs to be fed. By destroying vegetation, damaging wildlife habitats and disrupting natural processes, livestock grazing wreaks ecological havoc on riparian areas, rivers, deserts, grasslands and forests alike — causing significant harm to species and the ecosystems on which they depend.
In addition, the diets of many “grass-fed” herds are often supplemented with water-intensive crops like alfalfa. Studies have also shown that grass-fed cattle are responsible for more greenhouse gas emissions than those raised on grain feed — as much as 500 percent more — in addition to requiring more land and water per pound of beef. And while there are a lot of important reasons to support local agriculture, replacing meat one day per week with a plant-based meal saves more greenhouse gas emissions than eating an entirely local diet\'.
I can provide more evidence if anyone wants me too.
