Air Pollution: A Lethal Threat To Livestock?

Air pollution is a serious issue that affects both humans and animals. While the impact of air pollution on human health has been extensively studied, less is known about its effects on livestock. However, there is growing evidence that air pollution could be a contributing factor to the death of livestock. For example, in the 1870s, a dense industrial fog was linked to the death of cattle in England, and similar incidents occurred in Belgium in 1911 and during the Meuse valley air pollution episode in 1930. More recently, studies have found that food production, particularly livestock farming, is a significant source of air pollution, leading to thousands of deaths each year.

Air pollution from raising livestock causes poor air quality that leads to about 16,000 deaths a year in the US

The impact of air pollution from raising livestock on human health has been studied by researchers at the University of Minnesota. They found that 80% of the 16,000 deaths attributable to poor air quality from farming were linked to animal-based foods. This is roughly the same number of deaths caused by other sources of air pollution, including transportation and electricity generation.

The livestock industry has criticised these findings, calling the study "misleading" and arguing that there are no "federal methodologies for agriculture" to support the conclusions. However, the study is significant as it is the first of its kind to examine the air quality impacts of specific foods and production systems. Previous studies have focused on the climate change impacts of food production, water quality, water use, land footprints, and biodiversity impacts, but air quality impacts have received less attention.

In addition to the human health impacts, air pollution from livestock farming can also harm the animals themselves. There have been reports of pet and farm animal deaths during historic air pollution episodes, such as the dense industrial fog in England in the 1870s and the fog in Belgium in 1911.

Growing corn for livestock feed corresponds to 3,700 deaths every year

Air pollution from farms leads to thousands of deaths every year. In the United States, food production, primarily the raising of livestock, causes poor air quality that is responsible for about 16,000 deaths a year. Many of these deaths were in areas with high concentrations of livestock production and concentrated animal feeding operations (CAFOs).

Growing corn for food, fuel, and livestock feed corresponds to 3,700 deaths every year as a result of toxic air. Corn is a major component of livestock feed, and its production for this purpose has expanded to non-traditional growing areas, especially in the north. 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.

The impact of air quality due to corn grown to feed people is almost imperceptible in comparison. However, it is important to note that the impact of air pollution on livestock health is not well studied. There are reports of pet and farm animal deaths during historic air pollution episodes, such as the dense industrial fog in England in the 1870s and the Meuse valley air pollution episode in Belgium in 1930.

To reduce air pollution from agriculture, better management of waste from livestock and more efficient application of fertilizer are recommended. If all the suggested changes were applied to farms, scientists estimate that 7,900 lives could be saved every year. Additionally, a national dietary shift away from red meat could prevent 6,300 deaths.

Beef alone corresponds with 4,000 air pollution-related deaths every year

Air pollution from farms leads to thousands of deaths per year. In the United States, poor air quality from beef production alone is connected to about 4,000 deaths annually. When the authors of a study 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.

The raising of livestock causes poor air quality that is responsible for about 16,000 deaths a year in the United States. This is roughly the same number from other sources of air pollution, including transportation and electricity generation. Many of those deaths were in areas with high concentrations of livestock production and concentrated animal feeding operations (CAFOs).

In addition, dust kicked up by livestock in large animal feeding operations is associated with about 4,800 premature deaths per year. However, "secondary" particulate matter, which is generated when emissions from farms interact with other gases in the atmosphere, is even more problematic. This is especially true for ammonia, a highly reactive molecule released by manure and fertilizer, which can combine with other pollutants such as nitrogen and sulfur compounds to create small, hazardous particles.

Dust kicked up by livestock in large animal feeding operations is associated with about 4,800 premature deaths per year

Air pollution is a significant cause of death for both humans and animals. According to a study, air pollution from farms leads to 17,900 deaths in the US per year. This includes 98 premature deaths per year from air pollution in Duplin County, 89 of which are linked to emissions caused by hogs.

The raising of livestock, particularly in concentrated animal feeding operations (CAFOs), is a major source of air pollution. These operations are often located in areas with high concentrations of livestock production, such as North Carolina and the Upper Midwestern Corn Belt. The dust and emissions from these operations can lead to poor air quality and increased health risks for nearby populations.

In addition to the direct impact on human health, air pollution from livestock operations can also affect the animals themselves. Studies have investigated the effects of toxic gases, dusts, and endotoxins inside farm facilities on livestock health. While there is limited research on the association between ambient air pollution and animal mortality, there have been reports of pet and farm animal deaths during historic air pollution episodes.

The impact of air pollution from livestock operations extends beyond the immediate vicinity of the farms. Gases and particles released into the atmosphere can drift over long distances, affecting communities far from the source of pollution. This highlights the far-reaching consequences of air pollution from animal agriculture and the need for effective measures to mitigate its impact on human and animal health.

Manure and fertiliser released by farms can combine with other pollutants to create small, hazardous particles

Air pollution from farms is a leading cause of death for humans and animals. In the United States, it is responsible for 16,000 deaths a year, with many of these occurring in areas with high concentrations of livestock production.

The impact of air pollution from farms is not limited to human health. In the 1870s, the death of cattle during a livestock show in England was associated with a dense industrial fog. Similar incidents occurred in Belgium in 1911 and during the Meuse valley air pollution episode in 1930.

The widespread use of antibiotics in meat production is also contributing to the public health crisis of antibiotic resistance. Additionally, nutrients and other pollutants associated with animal manures and commercial fertilisers can negatively impact plant and animal life if not properly managed. This can lead to algae blooms, pathogens and nitrates in drinking water, and the emission of odours and gases into the air.
