The following refers to how mention of animal farming as a direct cause of climate change is constantly avoided. Indeed, this is demonstrated by the supposedly four "despairing" and hand-wringing articles in the May 2024 Guardian, that all "overlooked" to mention animal farming even once...
"With a small group of officials, Steinfield, head of the UN Food and Agriculture Organization (FAO)’s livestock policy branch, had been working for months on a report analysing the link between the six major species of livestock and climate change, which they all knew could be explosive. 'I was very frustrated by the fact that the livestock-environment issue hadn’t resonated even though people accepted in private that it was a big issue – for climate change, and also water and biodiversity,' he said. 'But no one was interested in getting into it because I think they were afraid of what it could mean...'
But although the link between climate change and fossil fuels was accepted and widely discussed, somehow the farming sector had managed to dodge the spotlight. Scientists were aware that the methane produced by grazing cattle – around two-thirds of livestock emissions come from cows – was a significant chunk of the anthropogenic greenhouse gases that were heating the planet’s atmosphere. Still, there had been no attempt to quantify how large a chunk it might be; the scientific community was largely focused elsewhere,..
Steinfeld remembered hearing complaints that 'the FAO has fallen into the hands of vegan activists' and personal threats such as 'the anti-livestock people are a pest that needs to be eradicated.' Pressure came from all sides. The big meat-producing countries – Brazil, Argentina, Uruguay and Paraguay, Australia and the US – all complained to the FAO’s higher echelons, according to Steinfeld, while protests also flooded in from 'the private sector, the large-scale meat, feed and dairy producers.'"

Veganism and the Environment
"Three in four of the world’s new or emerging infectious diseases come from animals. Responsible for three million deaths a year, these diseases are largely transmitted through
trading wildlife (legally and illegally) and factory farming."
Viva! 'Zoonotic diseases – 3 in 4'.
"The animal agriculture industry is the leading cause of most environmental degradation that is currently occurring. These detrimental effects happen as a result of overgrazing, habitat loss, overfishing and more. We are currently in the next mass extinction and animal agriculture is only fueling this catastrophe. Waste in the meat industry, too, is a major problem as well.
Animal agriculture’s impact...
- Processing one pound of beef uses 2,500 gallons of water, while it takes 477 gallons of water for eggs and nearly 900 gallons for cheese. Burning fossil fuels is the leading cause of climate change and the greenhouse effect has led to an unprecedented warming of the earth's temperature. Meanwhile, 82% of the world's underfed children live in countries where food is fed to livestock, and then sold to wealthier and developed countries. Animal agriculture produces 65% of the world's nitrous oxide emissions which has a global warming impact 296 times greater than carbon dioxide.
- Raising livestock for human consumption generates nearly 15% of total global greenhouse gas emissions, which is greater than all the transportation emissions combined. It also uses nearly 70% of agricultural land, contributing to deforestation, biodiversity loss and water pollution.
Ending our meat and dairy production could pause the increase of greenhouse gas emissions for 30 years, a new study suggests. All we need to do is adapt to a plant-based food system."

"U.S. farms cost the economy more in health and environmental damage than they contribute to the economy, according to a recent study in the Proceedings of the National Academy of the Sciences (PNAS). For 20 economic sectors, the study compares the cost of premature deaths from particulate air pollution to the value added to the economy. Farms performed worst, driven down by animal agriculture.
'At the margin, we're seeing that the damages from air pollution provided by farms are larger than the marginal value that the farms provide in economic terms,” said co-author Inês M.L. Azevedo, an associate professor in Stanford University.'"

The US government irresponsibly promotes animal abuse and environmental damage:
"The current Farm Bill allocates a staggering amount of taxpayer money to support animal agriculture. According to the Environmental Working Group, since 1995, $59 billion has been funneled into the meat, dairy, egg and seafood industries, while only a mere $124 million has gone to support alternative plant-based proteins...Animal agriculture is a leading cause of climate change, responsible for significant greenhouse gas emissions, deforestation, wildlife extinction and water pollution. Yet, instead of reducing subsidies to these harmful industries, the Farm Bill continues to prop them up, perpetuating a cycle of destruction."

Anti-vegans, in a futile attempt to justify their habit and deflect attention away from themselves, sometimes claim that even in Veganism, there is loss of life in the use of land.
Firstly, it’s impossible to live in this world without causing some harm and this is recognised in the definition of veganism. However, anyone concerned about “crop deaths” should be vegan.
Secondly, non-vegans are responsible for the deaths of those animals associated with the plant foods and plant products they eat (vegetables, fruits, beans, nuts, rice, pasta, bread etc.).
Thirdly, non-vegans are responsible for the deaths of those animals or those associated with the animals they consume. More crops are grown to feed farmed animals than humans.

Fourthly, in a vegan world, far less agricultural land would be required: "In the hypothetical scenario in which the entire world adopted a vegan diet the researchers estimate that our total agricultural land use would
shrink from 4.1 billion hectares to 1 billion hectares. A reduction of 75%. That’s equal to an area the size of North America and Brazil combined."
Source: https://ourworldindata.org/land-use-diets
Finally, in addition to the above, non-vegans are responsible for contributing to the annual needless suffering and death of an estimated 80 billion farmed animals and 2.5 trillion aquatic animals, together with the deaths associated with the devastating environmental and ecological impacts of animal agriculture and commercial fishing. Incidentally, one third of the annual global ocean fish catch is used to feed farmed animals.

In sum, non-vegans are demonstrably responsible for vastly more deaths than vegans.
Incredibly, some anti-vegans claim that more animals are killed through vegans pursuing their plant-based diets. They appear to simply repeat "what they've heard," or if they have
read it, it's from an article written by someone with no academic knowledge of the subject in some questionable libertarian periodical. An excellent article refuting this nonsense is 'Debunked: Do vegans kill more animals through crop deaths?'. Accessible here: https://www.surgeactivism.org/
A highly informative paper entitled 'How planting crops used to feed livestock is contributing to habitat destruction' states:
"Approximately 70 billion* farm animals are being raised for food annually. In 2015, people in the U.S. consumed 24.8 billion pounds of beef, with the majority of that cattle being raised in massive feedlots. Those cattle, in addition to other feedlot animals like chickens and pigs, are consuming 70 percent of the grain grown in the U.S.
According to the USDA’s website, corn, barley, oats, and sorghum are used as major feed grains in the U.S., with corn 'accounting for more than 95 percent of total feed grain and production use.' In the U.S., 36 percent of corn crops being used to feed livestock. Soy is also commonly used in feed, with 75 percent of global soybean crops being fed to livestock. To support these crops, one-third of arable land being used for feed production globally, using vast amounts of land and water resources."

"Livestock farming has a vast environmental footprint. It contributes to land and water degradation, biodiversity loss, acid rain, coral reef degeneration and deforestation.
Nowhere is this impact more apparent than climate change – livestock farming contributes 18% of human produced greenhouse gas emissions worldwide. This is more than all emissions from ships, planes, trucks, cars and all other transport put together.
Climate change alone poses multiple risks to health and well-being through increased risk of extreme weather events – such as floods, droughts and heatwaves – and has been described as the greatest threat to human health in the 21st century.
Meat production is highly inefficient – this is particularly true when it comes to red meat...The scale of the problem can also be seen in land use: around 30% of the earth’s land surface is currently used for livestock farming. Since food, water and land are scarce in many parts of the world, this represents an inefficient use of resources.
Feeding grain to livestock increases global demand and drives up grain prices, making it harder for the world’s poor to feed themselves. Grain could instead be used to feed people, and water used to irrigate crops. If all grain were fed to humans instead of animals, we could feed an extra 3.5 billion people. In short, industrial livestock farming is not only inefficient but also not equitable.
At the production level, industrial livestock farming relies heavily on antibiotic use to accelerate weight gain and control infection – in the US, 80% of all antibiotics are consumed by the livestock industry. This contributes to the growing public health problem of antibiotic resistance. Already, more than 23,000 people are estimated to die every year in the US alone from resistant bacteria. As this figure continues to rise, it becomes hard to overstate he threat of this emerging crisis."

"Our current food system, and its future trajectory, is simply not sustainable, and we need to fundamentally change the way we produce food if we are to feed 9-10bn people in 2050 without wrecking the planet irreversibly.' Those words were written by Pete Smith, Professor of Soils and Global Change at the University of Aberdeen, but they could have been written by any of the hundreds of people who have been researching the sustainability of our food habits during the last 20 years...
If we continue to try to meet that demand for food from animals, the damage will be catastrophic. The root of the problem is the sheer inefficiency of pastoral farming. It takes between five and 10kgs of grain to produce one kilogram of beef. That inefficiency shows itself in the massive amounts of land given over to crops like soya, which is fed to cattle. It is estimated that animal farming is responsible for 80 per cent of global deforestation, and, a recent World Wildlife Report says, “60 per cent of global biodiversity loss is down to meat-based diets.” With regard to water, the Institution of Mechanical Engineers has calculated that it takes over 15,000 litres of water to produce 1kg of beef, while the relevant figure for 1kg of potatoes is 287."

"Research conducted since Livestock’s Long Shadow has found that of all the habitable land on the planet, 45% is used for factory farming and pastures (Animal Equality 2015); 15% more than originally reported by the UN. It has also been reported that the original GHGE statistic of 18% annually is far from accurate. Goodland and Anhang (2009) found “livestock and their byproducts actually account for at least […] 51% of annual worldwide GHG emissions” (p. 11). The low figure may have been generated because sources of GHGE in animal agriculture are “underestimated, some are simply overlooked” (Goodland and Anhang 2009, p. 11). It is also estimated that
70 billion* animals are produced for food annually (Compassion in World Faming 2013; Animal Equality 2015). Thus, animal agriculture, it would appear, “is fundamentally unsustainable” (Compassion in World Farming 2013, p. 5).

"In 2012, livestock and poultry on the largest concentrated animal feeding operations (CAFOs) produced 369 million tons of manure: this was almost 13 times more waste than that of the entire US population of 312 million. 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. The mixture in lagoons consists not only of animal excrement but of bedding waste, antibiotic residues, cleaning solutions and other chemicals, and sometimes dead animals...
In 2015, the dead zone in the Gulf of Mexico, created by runoff from manure and other agricultural fertilizer in the Mississippi floodplain, was more than 5,000 square miles...
Untreated waste at CAFOs also pollutes the air with odors and creates health problems, markedly decreasing the quality of life of workers, people nearby and neighboring communities and property values...The US Environmental Protection Agency (EPA) estimates that nearly three quarters of the country’s ammonia pollution comes from livestock facilities, and studies have found high levels of antibiotics and antibiotic-resistant genes in air samples downwind of feedlots."

In conclusion, a 100% plant-based diet (e.g., vegan) has the least environmental impact."

"The world now produces more than four times the quantity of meat it did fifty years ago. In the United States, it is estimated that 70% of cows, 98% of pigs, 99% of turkeys, and 98% of chickens and eggs come from factory farms, according to a 2017 USDA report. And all of these factory farms have a tremendously detrimental impact on both our land availability and soil health. Industrialized livestock production uses a significant amount of land surface – 26% of the Earth’s ice-free land is used for livestock grazing, and one-third of the planet’s arable (farmable) land is occupied by crops for livestock feed, according to the UN Food and Agriculture Organization.
When comparing global land use of a meat-based diet to a plant-based diet, industrialized livestock grazing and growing livestock feed (primarily corn, soy, and oats) uses two and a half times more land than a plant-based diet. In the U.S., more than 70% of soy, 80% of corn, and 95% of oats that are grown are fed to livestock. Consuming a plant-based diet isn’t just a more efficient use of limited land resources, but also reduces the numerous negative impacts industrialized livestock production has on soil health. We explore some of these negative effects below."

This plant protein, which could go to starving people around the world, is used to feed animals. These animals don’t produce as many calories as the original plant protein would have. It takes about 13 pounds of grain to create a pound of meat. A lot more people can be fed with 13 pounds of grain than one pound of meat. The more people who transition to a vegan diet, the more awareness is called to this issue."

Coupled with horrifically high livestock mortality rates caused by poor standards of animal husbandry, among other factors, this waste represents not only a moral catastrophe but an environmental disaster...Currently, more than one-third of the calories produced by the world’s crops are being used for animal feed, and only 12 percent of those feed calories ultimately contribute to the human diet (as meat and other animal products). Producing 1kg of beef, for example, requires roughly 8kg of feed. With such low returns, does it still make sense for humanity to invest in livestock production?

"Current trends in food production and consumption are considered unsustainable. The world’s population is expected to increase by two billion people in the next 30 years; from 7.7 billion currently, to 9.7 billion in 2050, according to the United Nations. Just satisfying the expected human food and animal feed demands would require increasing global food production by 70% Intensification with increased resource use simply will not produce enough to meet the huge demand. We need to find a different way to achieve global food security without expanding crop and pastureland and without increasing greenhouse gas emissions.
A study evaluating the environmental impact of various diets found that 5-13% of the environmental impact of diet is due to land use changes. This includes deforestation as well as desertification arising from agricultural expansion for products not used to feed the local human population, but instead exported to developed countries as cattle feed. This makes no sense as increasing populations are placing unprecedented demands on agriculture and natural resources. Around a billion people are currently chronically malnourished while our agricultural systems continue to degrade land, water, biodiversity and climate on a global scale. Europe can grow enough vegetable protein to feed all its people, but not all its farmed animals too. Only 20% of the protein fed to animals in Europe originates in Europe, the rest is imported from other countries, including developing ones, which plays an important role in the further impoverishment of these countries and the exploitation of their environmental resources. Not to mention the malnourishment of their populations.
Changing land use for livestock production is directly linked to deforestation. For the UK, when land use change emissions are considered, about a half the food chain emissions arise outside the UK. So, where your food comes from matters. Land use changes (mainly deforestation) driven by agricultural expansion is a major source of emissions attributable to global food production and the UK plays an important part. In a study conducted for the conducted for WWF-UK and the Food Climate Research Network, it was estimated that global land use change emissions account for 40% of the emissions embedded in food consumed in the UK. Deforestation is a large source of emissions and expansion of agriculture is the biggest driver. The world’s limited resources simply cannot keep pace with our hunger for animal-based foods."

Around a third of food produced globally ends up going to waste, either during production, transport, or by households and retailers. Researchers from Leiden University have calculated for the first time the animal cost embodied in waste across the whole food supply chain...The researchers calculate that cutting meat loss and waste to the lowest levels across the food supply chain globally could spare 7.9 billion animal lives. This would not affect how much meat humans consume. “The number of animal lives lost or wasted is huge but not surprising,” Laura Scherer, Assistant Professor of Environmental Sciences and one of the study’s authors, told
Plant Based News. “It is a result of the about 75 billion animals used for the production of the six meat types we considered.”...
Globally, food loss and waste accounts for 10 percent of all greenhouse gas (GHG) emissions. But the study points out that wasted meat has a relatively bigger environmental impact than wasted plant-based foods. Wasted beef has a particularly big impact; it takes 100 times more land to produce a gram of protein from cows compared to peas or tofu. All animal products also use more of other resources like water and emit more GHGs than almost all plant foods. But when the number of animal lives lost through wastage are invisible, so too are their associated environmental costs, according to the researchers."

In 2021, research from Our World In Data suggested that if we collectively shifted to a reliance on plant-based agriculture instead of animal agriculture, we could reduce land use by 75 percent, which would help to mitigate issues like deforestation and biodiversity loss. And in 2022, researchers from Stanford University and the University of California suggested that phasing out animal agriculture and switching to a global plant-based diet, would “effectively halt the increase of atmospheric greenhouse gases” for a period of 30 years. This, in turn, would allow humans the time to figure out a transition away from fossil fuels."

"The Stern Report discussed the effect of global warming on the world economy. They said cutting greenhouse gas emissions would cost a lot of money (about 1% of the world’s GDP), but doing nothing will cost the world a lot more, anything from five-20 times more. They warned that we face losing up to a fifth of the world’s wealth from unmitigated climate change that if unchecked, will devastate the global economy on the scale of the Great Depression or the 20th century’s world wars. Written more than a decade ago, the report said: “So prompt and strong action is clearly warranted.”[1]
Climate change will have a devastating impact on food yields around the world. Many areas, for example, sub-Saharan Africa, are likely to be affected in terms of both nutrition and incomes.[2] Severe crop losses are predicted in areas that already struggle with poor food security, such as South Asia and southern Africa. Scientists predict that over just two decades, Southern Africa could lose more than 30% of its main crop, maize, by 2030 and in South Asia, losses of many regional staples, such as rice, millet and maize could be as high as 10%.[3]
These are just some of the reasons why climate change will affect the lives and safety of large numbers of people around the world.
The true cost of cheap meat is becoming more and more evident. Today, animal agriculture is one of the top contributors to serious environmental problems including the emission of greenhouse gases and global warming.
A 2017 landmark study found that the top three meat firms – JBS, Cargill and Tyson – emitted more greenhouse gases in 2016 than all of France, and the top 20 meat and dairy companies emitted more greenhouse gases in 2016 than all of Germany – Europe’s biggest climate polluter by far. It’s clear that that the world cannot avoid a climate catastrophe without addressing the staggering emissions from the meat and dairy industries.[4]
A central problem is the clear lack of transparency in the animal agriculture industries. In 2019, the FAIRR Protein Producer Index ranked 60 of the largest global meat, dairy and fish producers by looking at sustainability risk factors including greenhouse gas emissions, the use of antibiotics and deforestation. Their report said that in stark contrast to the transport sector, only one in four meat, fish and dairy producers even measure their greenhouse gas emissions, let alone act to reduce them.[5]
These 60 producers are the hidden suppliers to household names such as McDonald’s, Burger King and Marks & Spencer. Together, they make up around one-fifth of the global livestock and aquaculture market – that’s one in every five burgers, steaks or fish.
The FAIRR report says: “We now know processing 70 billion* animals for 7 billion humans every year produces more than 14% of the world’s greenhouse gas emissions – more than the whole transport sector. We know the livestock industry is the single largest driver of habitat loss worldwide. We also know that 73% of all antibiotics are used in factory farming, in many instances to help animals grow faster, accelerating the development of superbugs.”[5]

"'Climate change is a hunger risk multiplier, threatening to undermine hard-won gains in eradicating hunger and poverty. Current projections indicate that unless considerable efforts are made to improve vulnerable people’s resilience, 20 percent more people will be at risk of hunger by 2050 due to the changing climate.' But it’s not just via climate change that animal agriculture contributes to food insecurity. Farming animals is notoriously inefficient and wasteful when compared to growing plants to feed humans directly, with the end result that 'livestock' animals take drastically more food from the global food supply than they provide. This is because in order to eat farmed animals, we have to grow the crops necessary to feed them, which amounts to vastly more crops than it would take to feed humans directly. (In 2023, we feed and slaughter some 75+ billion land animals every year; there are 8+ billion humans on earth). To give one example, it takes 25 pounds of grain to yield just one pound of beef — while crops such as soy and lentils produce, pound for pound, as much protein as beef, and sometimes more.
Compounding this inefficiency is the fact that only a small fraction of the plant energy consumed by an animal is converted into edible protein. Most of the energy from crops fed to farmed animals is used to fuel their own metabolism, with only a fraction of those grains and other plants being turned into meat."

"The proportion of water used to produce animal products is not small. In fact, it’s estimated that meat and dairy are responsible for around a third to 40 per cent of agriculture’s water demands. Given that animal products only provide 18 per cent of the world’s calories this is an inefficient use of an extremely limited resource...
One acre of land can yield between 2-20 times more plant food than animal-based foods. Writes Richard Oppenlander, 'We are essentially using twenty times the amount of land and crops, and hundreds of times the water, as well as polluting our waterways and air and destroying rainforests, to produce animals to kill and eat … which is unhealthier than eating the plant products we could have produced.' In fact, analysis of global agricultural yields finds that better use of existing croplands could feed four billion more people simply by shifting away from growing crops for animal feed and fuel, and instead growing crops for direct human consumption. Reallocating croplands in this way could increase available global food calories by as much as 70 percent, according to researchers."

"Billions of animals are raised for food around the world. With so many individuals being born, living, and then being killed in a constant cycle that is kept as short as possible to maximize profits, it comes as no surprise that the impact of animal agriculture on water is considerable. Factory farms’ contributions to water pollution stem from the animals and their waste, the operations of the farms, and the production of food for the animals. The pollution caused by these facilities has far-reaching impacts, contributing to disease outbreaks, driving algal blooms, and negatively impacting economies that depend on clean water...
Agriculture contributes to the presence of heavy metals in water. Though there are many industrial sources of such contamination, fertilizer, pesticides, manure, and irrigation play significant roles. Heavy metal exposure has been linked to a number of health conditions including weakened bones, liver and lung damage, and cancer...A variety of zoonotic diseases can be spread from animals being raised for food to humans and other animal populations via water. One of the major ways that such diseases are introduced to water is through the fecal matter of an infected animal. Diseases that can be transmitted this way include E. coli and Cryptosporidium.
Conclusion: Water pollution is a serious problem not only because it compromises the integrity of the environment, but also because it causes health problems, and potentially death, for a wide range of animals, while also allowing the spread of zoonotic disease. In order to prevent the further degradation of water systems, we must change the way that we eat, by focusing more on eating, and producing, plant-based foods instead of continuing to farm animals en masse on factory farms."

"Globally, 26 per cent of all the world’s ice-free land surface is given to grazing animals and in total animal agriculture uses 83 per cent of all agricultural land, yet it provides less than 20 per cent of the calories consumed and less than 40 per cent of the protein that is consumed.
In the UK, it is estimated that 85 per cent of the land that is used for agriculture is just for animals, which is almost 50 per cent of the entire landmass of the UK. And in the US, 41 per cent of the entire landmass is for animal farming compared to four per cent which is used to grow plants directly for humans, with half of all agricultural land in the US being used specifically for beef production even though it makes up only three per cent of dietary calories."

"All farming requires the use of resources, but ‘livestock’ farming tends to be more resource-intensive than alternatives. Two key farming resources are land and water. In terms of land, ‘livestock’ farming accounts for 70 per cent of all agricultural land worldwide. It also uses a third of all arable land, to provide crops to feed ‘livestock’. Providing this land exacerbates deforestation (Kemmerer, 2015), in turn eroding planetary capacity to absorb carbon dioxide (CO2). CO2 is a key greenhouse gas (GHG) responsible for anthropogenic climate change (that is, caused by human activity) (Garnett, 2013). By contrast, a recent research review concluded that plant-based diets could sustain the global human population from half the agricultural land currently in use (Chai et al., 2019). In terms of water, ‘livestock’ farming often depends on irrigation using finite fresh water supplies. Animal-protein production has been calculated to use more than four times as much water as the most intensively-irrigated plant-based protein production (Reynolds et al., 2014). Globally, ‘livestock’ farming is responsible for 29 per cent of agricultural fresh water use (Chai et al., 2019)."

(i)Anti-vegans will sometimes claim that vegans, in using soy, are causing extensive environmental damage. In reality, the facts show a very different picture...
"More than three-quarters (77%) of global soy is fed to livestock for meat and dairy production. Most of the rest is used for biofuels, industry or vegetable oils. Just 7% of soy is used directly for human food products such as tofu, soy milk, edamame beans, and tempeh. The idea that foods often promoted as substitutes for meat and dairy – such as tofu and soy milk – are driving deforestation is a common misconception...
When someone mentions soy we often think about foods such as tofu, soy milk, tempeh or edamame beans. This feeds into the argument that meat and dairy substitutes – such as switching from meat to high-protein tofu, or from dairy to soy milk – is in fact worse for the environment. But, only a small percentage of global soy is used for these products. More than three-quarters (77%) of soy is used as feed for livestock.
One-fifth of the world’s soy is used for direct (i.e. not from meat and dairy) human consumption. Most of this is first processed into soybean oil. Typical soy products such as tofu, soy milk, tempeh and edamame beans account for just 7% of global demand. Soy can also be used for industrial purposes. Around 4% is used for biofuels, lubricants and other industrial processes. Biodiesel alone accounts for 2.8%."
