Factory Farming Creates Noxious Odors and Dangerous Air Pollution
By Samantha Bell
Imagine driving through the rolling, green pastures of central Pennsylvania. Surrounded by wide open fields and mountains in the distance, you are taken in by the immense natural beauty. Then it hits you, like a thick wall of putrid bricks: the smell of manure. Next thing you know, you’re gasping for air and high-tailing your way out of there.
Something we haven’t all quite grasped yet is the real impact that all of these smelly farms are having on our air quality. Around 99 percent of all farm animals are raised in one of the 20,000 factory farms in the U.S, according to the National Trust for Historic Preservation. Concentrating millions of animals on to factory farms has a number of negative effects.
Crowded by the thousand into small sheds and stalls, these animals know nothing but fear and stress during their severely shortened lives. Starting with animal cruelty, the harmful repercussions of factory farms radiates to the surrounding environment.
Livestock in the U.S. produce 500 million tons of waste every year, according to the Pew Commission on Industrial Farm Animal Production. This amount is more than three times the sewage produced by the entire U.S. human population. This is also 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, according to the National Association of Local Boards of Health. In effect, this waste is a pollutant, not a productive farming tool as some might believe, according to New York University.
When you’re driving through the countryside and smell manure, it is likely coming from one of these lagoons, but the smell is really the least of our worries.
Toxic Gases from Factory Farm Waste
The mountains of manure from factory farms can release around 400 different harmful gases into the atmosphere, according to the Farm Safety Association. Some of these gases include nitrous oxide, methane, carbon dioxide, ammonia and hydrogen sulfide. Because animals are kept by the thousand, the concentration of these gases can be extremely dangerous to the local community. Many of these gases also influence greenhouse gases that contribute to environmental damage and climate change.
If you have ever used products containing ammonia, you know how overwhelming the smell can be. It is for this reason that opening windows and ensuring proper ventilation are always recommended when using anything ammonia-based. But when thousands of tons of ammonia are being released directly into outdoor air, how is one supposed to escape the irritating effects of this gas?
The sad answer is, you can’t. That is what it is like to live near a factory farm.
Around 80 percent of ammonia emission in the U.S. come from farm animal waste. This noxious gas can cause a variety of harmful health effects, including dizziness, eye irritation, respiratory illness and nausea, according to the Natural Resources Defense Council (NRDC).
In addition to ammonia, factory farm waste releases dangerous levels of hydrogen sulfide. Exposure to this gas, even in small doses can cause sore throats, but more troublingly, seizures, comas and even death, according to the NRDC.
While adults are highly susceptible to these gases, according to the Center for Disease Control (CDC), children, who take in 20-50 percent more air, are at extreme risk. As a result, children raised in communities near factory farms are more likely to develop asthma or bronchitis. Low air quality can stimulate asthma symptoms, making living near these farms even more dangerous.
The CDC also states that mental health deterioration and increased sensitivity to smells can occur in people who live near factory farms.
Having to live with the smell and the harmful gases released by farm waste can ruin not only people’s health, but their entire lives. Sadly, many communities located near factory farms fall below the poverty level, meaning people cannot afford to relocate – even if their family’s lives depend on it.
Factory farms emit greenhouse gases into the atmosphere just as readily as industrial smokestacks and tailpipes. Globally, 37 percent of methane emissions come from livestock production, according to EcoWatch.org. Methane can trap up to 100 times more heat in the atmosphere than carbon dioxide over a five-year period. But methane is hardly the only damaging gas released by farm waste.
Topping out methane’s powerful global warming potential is nitrous oxide. This gas is about 296 times more potent than carbon dioxide. When nitrous oxide mixes with ammonia, it creates nitric acid, which causes acid rain, according to the EPA. Acid rain not only causes statues to deteriorate, but it sucks minerals from soil, destroys forest ecosystems, and can cause massive fish kills.
What Can You Do?
Avoiding air pollution from factory farms is no easy task. While you could carry around protective facemasks with you everywhere, this hardly solves the root of the problem. One of the best things that you can do to help lower the amount of air pollution produced by factory farms is to stop supporting them.
Factory farms only exist to meet high demands for meat, dairy and eggs. When we lower demand for these products, factory farms begin to lose their value. Switching to a plant-based diet is a great way to achieve this, but even if you reduce your consumption of meat and other animal products, it will slowly make a difference.
