Air Pollution's Deadly Impact On Livestock

Air pollution is a pressing issue that affects both humans and animals. While there have been studies on the impact of air pollution on human health, there is limited research on its effects on livestock. However, it is known that air pollution from farms and the raising of livestock contributes to thousands of deaths each year. This raises the question: could air pollution be a direct cause of death in livestock?

Air pollution from raising livestock accounts for most of the 16,000 US deaths each year

Air pollution from raising livestock is a major cause of death in the United States, with around 16,000 deaths a year attributed to poor air quality caused by the livestock industry. This figure is roughly the same as the number of deaths caused by other sources of air pollution, such as transportation and electricity generation. The impact of the livestock industry on air quality is particularly notable in areas with high concentrations of livestock production and concentrated animal feeding operations (CAFOs), including North Carolina and the Upper Midwestern Corn Belt.

The study that revealed these findings, published in the journal Proceedings of the National Academies of Sciences, is the first of its kind to examine the air quality impacts of specific foods and production systems. Led by Professor Jason Hill of the University of Minnesota, the research tracked how different agricultural products increased levels of fine particulate matter, or PM 2.5, in the air. PM 2.5 exposure has been linked to serious health issues, including heart disease, cancer, stroke, and respiratory illnesses.

The livestock industry has disputed the findings of the study, claiming that it is based on "faulty assumptions and riddled with data gaps". However, the study adds to a growing body of evidence on the negative health impacts of air pollution, both for humans and animals. Previous studies have investigated the effects of toxic gases, dust, and endotoxins inside farm facilities on livestock health, as well as the impact of urban air pollution on pet animals.

While the exact number of deaths attributable to air pollution from raising livestock may be debated, it is clear that the livestock industry contributes significantly to poor air quality, with potential consequences for the health of both humans and animals. Further research and regulation are needed to address these concerns and mitigate the impact of the livestock industry on air quality and public health.

Air pollution from farms leads to 17,900 US deaths per year

The study also found that "primary" PM 2.5 is associated with about 4,800 premature deaths per year. PM 2.5 exposure can lead to heart disease, cancer, stroke and respiratory illnesses. These particles are directly produced when farmers till fields or burn crops before harvest. They can also come in the form of dust kicked up by livestock in large animal feeding operations.

The impact of air pollution from farms is not limited to human health. A study on dairy cattle adds to the epidemiologic findings in humans and reinforces the evidence on the plausibility of causal effects. The study found that air pollution associations go beyond short-term mortality displacement. Other studies have investigated the effects of toxic gases, dusts and endotoxins inside farm facilities on livestock health.

The negative impact of air quality due to the production of livestock and the crops they require is significant. When the study's authors calculated the air quality-related deaths caused by producing livestock and the crops they require, they found that beef alone corresponded with 4,000 air pollution-related deaths every year. When pork and dairy production were added to the calculation, such production contributed to 9,100 deaths annually.

Air pollution from beef production alone corresponds with 4,000 deaths every year

The study, published in the journal Proceedings of the National Academies of Sciences, is the first to examine the air quality impacts of specific foods and production systems. It found that 80% of the 16,000 deaths are related to producing animal products such as meat, dairy and eggs. When pork and dairy production are added to the calculation, such production contributes to 9,100 deaths annually.

The negative impact of air quality due to corn grown to feed livestock is also significant, with 3,700 deaths every year as a result of toxic air. This is in contrast to vegetables, which contribute to 100 deaths annually.

There have been few studies investigating the effects of air pollution on animal health in an epidemiologic context. However, there are reports of pet and farm animal deaths during historic air pollution episodes.

Air pollution from pork and dairy production contributes to 9,100 deaths annually

The study also found that beef production alone corresponds with 4,000 air pollution-related deaths every year. When pork and dairy production are added to the calculation, the number of deaths increases to 9,100. This is in contrast to vegetables, which contribute to only 100 deaths annually.

The negative impact of air quality due to the raising of livestock has been largely overlooked until recently. While there has been a lot of focus on the climate change impacts of food production, water quality, water use, land footprints, and biodiversity impacts, the air quality impacts have often been missing from the discussion.

Fine particulate matter, or PM 2.5, is one of the main contributors to poor air quality in areas where livestock is raised. PM 2.5 exposure can lead to serious health issues, including heart disease, cancer, stroke, and respiratory illnesses.

Few studies have investigated the effects of air pollution on animal health

One study has found that air pollution from farms leads to 17,900 US deaths per year. This includes the impact of dust kicked up by livestock in large animal feeding operations. Another study found that the raising of livestock causes poor air quality that is responsible for about 16,000 deaths a year in the United States.

When the study's authors calculated the air quality-related deaths caused by producing livestock and the crops they require, they found that beef alone corresponded with 4,000 air pollution-related deaths every year. When pork and dairy production were added to the calculation, such production contributed to 9,100 deaths annually.

There have been some reports of pet and farm animal deaths during historic air pollution episodes, but these are limited.
