Book Description

An investigation into what it means to eat meat in the modern world.

If You Just Remember One Thing

The low price of meat hides its true societal costs in environmental damage, health risks, and extensive animal s... More

Bullet Point Summary and Quotes

  1. Food choices are deeply intertwined with personal values, family narratives, and our past.
    1. Foer's grandmother refused non-kosher pork even when starving, because "If nothing matters, there's nothing to save."
  2. Foer went from disliking animals to deeply loving his adopted dog. This prompts him to question the inconsistent ways humans relate to different animal species.
  3. The societal taboo against eating dogs is illogical and hypocritical when compared to the widespread consumption of other intelligent animals like pigs.
  4. Modern industrial animal agriculture, including factory farming and industrial fishing is characterized by cruelty at immense scale, and a reliance on consumer ignorance of these practices.
  5. We are complicit in animal suffering when we ignore the harsh realities, but personal encounters with it can force a moral reckoning.
  6. “It's always possible to wake someone from sleep, but no amount of noise will wake someone who is pretending to be asleep.”
  7. Foer investigates a turkey farm with an activist. They found tens of thousands of small turkey chicks densely packed under heat lamps in a wholly artificial, windowless environment. They saw many dead, dying, or deformed chicks scattered throughout, with others showing physical alterations like sores and blackened beaks and toes.
  8. A factory farmer defends the industry, citing the need to feed billions affordably and efficiently, and that consumer demand for cheap food drives current practices.
  9. The price of meat is artificially low because it fails to reflect its true production costs, which are largely borne by society. These hidden costs include environmental damage, health risks from antibiotic overuse, and primarily, animal suffering.
  10. “These factory farmers calculate how close to death they can keep the animals without killing them. That's the business model. How quickly can they be made to grow, how tightly can they be packed, how much or little can they eat, how sick can they get without dying.”
  11. The factory farming industry is very secretive, exemplified by locked farm doors, unanswered letters, and efforts to thwart independent research.
  12. Factory farming has bred chickens into highly specialized "broilers" for meat and "layers" for eggs. The chickens live their entire lives in artificial systems.
  13. Chickens in factory farms endure immense suffering from cramped, unsanitary conditions, painful mutilations like beak trimming, and inhumane slaughter. The resulting meat is often then artificially plumped and contaminated in "fecal soup" (a large tank of water full of chicken) to increase weight and profit.
    1. "The next stop on the line for the immobile-but-conscious bird will be an automated throat slitter... about 180 million chickens are improperly slaughtered each year... I spoke to numerous catchers, live hangers, and kill men who described birds going alive and conscious into the scalding tank."
  14. Modern industrial animal agriculture, particularly poultry and pig farming, creates ideal conditions (overcrowding, stress, genetic uniformity, fecal contamination) for viruses to emerge, mutate, and jump to humans, catapulting the risk of new pandemics like the bird flu (H5N1) or swine flu (H1N1).
  15. The routine non-therapeutic use of antibiotics in factory-farmed animals contributes significantly to the rise of antimicrobial-resistant pathogens that threaten human health.
  16. The powerful meat, dairy, and egg industries exert considerable influence over government nutritional guidelines (e.g., via the USDA) and public health information, often downplaying the health risks associated with their products and resisting beneficial regulations.
  17. Factory farming giants like Smithfield generate enormous quantities of toxic animal waste, causing severe environmental pollution (water, air, land) and significant health risks for nearby communities.
  18. Industrial pig farming genetically modifies pigs for traits like leanness and rapid growth, which leads to increased stress and health problems.
  19. Pigs on factory farms endure immense suffering, partly because their natural social behaviors are suppressed in cramped environments. Breeding sows are confined to tiny gestation crates during constant pregnancies, while their piglets face painful mutilations like tail docking and castration without anesthesia. These piglets are then forced into severely overcrowded pens, where unprofitable ones are brutally killed.
    1. “Thumping” is a common practice where slow-growing piglets are inhumanely killed by slamming their heads into the ground.
    2. “These cages are stacked one on top of the other, and feces and urine fall from higher cages onto the animals below. Growers will keep piglets in these cages as long as possible before moving them to their final destination: cramped pens. The pens are deliberately overcrowded because, as one industry magazine says, 'overcrowding pigs pays.' Without much room to move, the animals burn fewer calories and get fatter on less feed.”
  20. Aquaculture (industrial fish farming) shares similar problems as land industrial farming, including extreme overcrowding, rampant disease (like sea lice), and inhumane slaughter methods.
    1. “A major source of suffering for salmon and other farmed fish is the abundant presence of sea lice, which thrive in the filthy water. These lice create open lesions and sometimes eat down to the bones on a fish's face -- a phenomenon common enough that it is known as the “death crown” in the industry. A single salmon farm generates swarming clouds of sea lice in numbers thirty thousand times higher than naturally occur.”
    2. "Many scientists predict the total collapse of all fished species in less than fifty years -- and intense efforts are under way to catch, kill, and eat even more sea animals. Our situation is so extreme that research scientists at the Fisheries Centre of the University of British Columbia argue that 'our interactions with fisheries resources [also known as fish] have come to resemble ... wars of extermination.'"
  21. Factory farms have largely replaced traditional farmers, leaving remaining workers in stressful, dehumanizing, low-paying roles like slaughter. These poor conditions lead them to commit sadistic acts of deliberate cruelty against animals. The perpetrators are rarely punished.
    1. "...workers have been documented using poles like baseball bats to hit baby turkeys, stomping on chickens to watch them 'pop,' beating lame pigs with metal pipes, and knowingly dismembering fully conscious cattle."
    2. "When Temple Grandin first began to quantify the scale of abuse in slaughterhouses, she reported witnessing 'deliberate acts of cruelty occurring on a regular basis' at 32 percent of the plants she surveyed during announced visits in the United States."
  22. The UN states livestock causes 18% of greenhouse gas emissions (40% more than all transportation wastes combined). Animal agriculture is a primary source of potent anthropogenic methane (37%, 23x CO2's warming potential) and nitrous oxide (65%, 296x CO2's potential). Omnivorous diets produce seven times the greenhouse gases of vegan diets.
  23. “Today, animal products still account for only 16 percent of the Chinese diet, but farmed animals account for more than 50 percent of China's water consumption.”
  24. “Less than 1% of the animals killed for meat in America come from family farms.”
  25. “Just how destructive does a culinary preference have to be before we decide to eat something else? If contributing to the suffering of billions of animals that live miserable lives and (quite often) die in horrific ways isn't motivating, what would be? If being the number one contributor to the most serious threat facing the planet (global warming) isn't enough, what is? And if you are tempted to put off these questions of conscience, to say not now, then when?”
  26. “It shouldn't be the consumer's responsibility to figure out what's cruel and what's kind, what's environmentally destructive and what's sustainable. Cruel and destructive food products should be illegal.”
