Why Vegan?

1. Animal liberation is a moral imperative akin to other civil rights movements

The struggle against this tyranny is a struggle as important as any of the moral and social issues that have been fought over in recent years.

Expanding moral circles. Throughout history, humanity has gradually expanded its circle of moral consideration to include previously marginalized groups. The animal liberation movement seeks to extend this circle further to include non-human animals. This expansion is based on the recognition that animals, like humans, can suffer and have interests that deserve consideration.

Philosophical foundations. The case for animal liberation rests on fundamental ethical principles, such as the equal consideration of interests. Philosophers like Peter Singer argue that the capacity to suffer is the key criterion for moral status, not arbitrary characteristics like species membership. This view challenges traditional anthropocentric ethics and calls for a radical reassessment of our treatment of animals.

Practical implications. Accepting animal liberation as a moral imperative requires significant changes in various aspects of human society, including:

• Diet: Shifting away from animal products
• Entertainment: Eliminating animals in circuses, zoos, and sports
• Fashion: Banning fur and leather
• Research: Finding alternatives to animal testing
• Law: Extending legal protections to animals

2. Factory farming inflicts immense suffering on billions of animals annually

Under such crowded conditions, the more aggressive birds peck at the weaker hens in the cage, who are unable to escape. To prevent this pecking leading to fatalities, producers sear off all the birds' beaks with a hot blade.

Scale of the problem. Factory farming is responsible for the suffering of billions of animals each year. In the United States alone, nearly 10 billion land animals are raised and slaughtered for food annually. This industrial-scale production prioritizes efficiency and profit over animal welfare, resulting in severe physical and psychological distress for the animals involved.

Cruel practices. Common practices in factory farming include:

• Extreme confinement: Pigs in gestation crates, hens in battery cages
• Painful procedures: Debeaking, tail docking, castration without anesthesia
• Unnatural growth: Selective breeding and hormones for rapid weight gain
• Separation of mothers and offspring: Early weaning of calves and piglets
• Inhumane slaughter: High-speed killing lines, improper stunning

Hidden from view. Most consumers are unaware of the realities of factory farming, as the industry keeps these practices hidden from public view. Increased transparency and education about these conditions are crucial for driving change in animal agriculture.

3. Speciesism: The unjustified prejudice against non-human animals

If possessing greater intelligence does not entitle one human to exploit another, why should it entitle humans to exploit nonhumans?

Defining speciesism. Speciesism is the unjustified discrimination against individuals based solely on their species membership. It is analogous to other forms of prejudice like racism or sexism, where morally irrelevant characteristics are used to deny equal consideration to certain groups.

Challenging assumptions. The concept of speciesism challenges deeply ingrained societal beliefs about human superiority and the right to use animals for human purposes. It calls into question:

• The idea that animals exist for human use
• The belief that human interests always trump animal interests
• The assumption that animals lack cognitive or emotional complexity

Implications of rejecting speciesism. Abandoning speciesist attitudes requires a fundamental shift in how we view and treat animals:

• Recognizing animal sentience and individuality
• Considering animal interests in moral decision-making
• Reevaluating practices that harm animals for human benefit
• Extending legal and ethical protections to non-human animals

4. Animal experimentation often involves cruel practices with questionable benefits

Ryder gives a selection of experiments, taken from recent scientific journals. I will quote two, not for the sake of indulging in gory details, but in order to give an idea of what normal researchers think they may legitimately do to other species.

Ethical concerns. Animal experimentation raises serious ethical issues due to the suffering inflicted on sentient beings. Many experiments involve subjecting animals to pain, distress, and death, often without adequate pain relief or humane endpoints. The justification that these practices benefit humans is questionable, as many experiments have limited applicability to human health.

Questionable scientific value. Critics argue that animal experiments often have limited predictive value for human outcomes due to:

• Physiological differences between species
• Artificial nature of induced diseases in animals
• Poor reproducibility of many animal studies
• Publication bias favoring positive results

Alternatives to animal testing. Advances in technology are providing increasingly sophisticated alternatives to animal experimentation:

• In vitro cell and tissue cultures
• Human organ-on-a-chip models
• Computer simulations and AI-driven predictive models
• Human volunteer studies and epidemiological research

5. The environmental impact of meat production is severe and unsustainable

To convert eight or nine kilos of grain protein into a single kilo of animal protein wastes land, energy, and water. On a crowded planet with a growing human population, that is a luxury that we are becoming increasingly unable to afford.

Resource intensity. Animal agriculture is an incredibly inefficient way to produce food. It requires vast amounts of land, water, and energy to grow crops for animal feed, which is then converted into a much smaller amount of meat, dairy, or eggs. This process wastes valuable resources that could be used more efficiently to feed people directly.

Environmental degradation. The meat industry contributes significantly to various forms of environmental damage:

• Deforestation: Clearing land for grazing and feed crops
• Water pollution: Runoff from animal waste and agricultural chemicals
• Air pollution: Methane emissions from livestock
• Biodiversity loss: Habitat destruction and ecosystem disruption

Climate change impact. Animal agriculture is a major contributor to greenhouse gas emissions, responsible for approximately 15% of global emissions. This is comparable to the entire transportation sector. Reducing meat consumption is therefore one of the most effective individual actions for combating climate change.

6. Vegetarianism and veganism are ethical choices with significant positive impacts

Going vegan is a simpler choice that sets a clearcut example for others to follow.

Ethical considerations. Adopting a vegetarian or vegan diet is a powerful way to align one's actions with ethical beliefs about animal welfare and environmental protection. It reduces direct participation in systems that cause animal suffering and environmental degradation.

Health benefits. Plant-based diets, when well-planned, can provide all necessary nutrients and offer several health advantages:

• Lower risk of heart disease, type 2 diabetes, and certain cancers
• Improved weight management
• Reduced exposure to antibiotics and hormones used in animal agriculture

Environmental impact. Choosing plant-based foods can significantly reduce an individual's environmental footprint:

• Lower greenhouse gas emissions
• Reduced water consumption
• Less land use and deforestation
• Decreased pollution from animal waste and agricultural runoff

7. Fish feel pain and suffer in commercial fishing practices

Victoria Braithwaite, a professor of fisheries and biology at Pennsylvania State University, has probably spent more time investigating this issue than any other scientist. Her recent book Do Fish Feel Pain? shows that fish are not only capable of feeling pain, but also are a lot smarter than most people believe.

Scientific evidence. Recent research has demonstrated that fish possess the neurological structures necessary to experience pain and show behavioral and physiological responses consistent with pain perception. This challenges the long-held belief that fish are incapable of suffering.

Commercial fishing practices. Many common fishing methods inflict significant suffering on fish:

• Suffocation on deck after being caught in nets
• Crushing under the weight of other fish in trawl nets
• Decompression injuries when pulled from deep waters
• Impalement on hooks for extended periods in longline fishing

Ethical implications. Recognizing fish sentience and capacity for suffering necessitates a reevaluation of fishing practices and fish consumption. It calls for:

• Development of more humane fishing and aquaculture methods
• Consideration of fish welfare in fisheries management
• Reduction in fish consumption or adoption of plant-based alternatives

8. Cultured meat technology offers a potential solution to animal suffering and environmental concerns

Can we therefore all breathe a sigh of relief, because technology will save us from catastrophic climate change? Not yet. Even if the world were to move to an entirely clean power supply, and use that clean power to charge up an all-electric fleet of cars, buses and trucks, one major source of greenhouse gas emissions would continue to grow: meat.

Technological innovation. Cultured meat, also known as lab-grown or cell-based meat, involves growing animal cells in a controlled environment to produce meat without raising and slaughtering animals. This technology has the potential to address both animal welfare and environmental concerns associated with conventional meat production.

Benefits of cultured meat:

• Elimination of animal suffering in meat production
• Reduced land, water, and energy use compared to conventional farming
• Lower greenhouse gas emissions
• Potential for enhanced food safety and nutritional control

Challenges and considerations. While promising, cultured meat technology still faces several hurdles:

• Scaling production to commercial levels
• Reducing costs to compete with conventional meat
• Gaining regulatory approval and consumer acceptance
• Ensuring the energy efficiency of production processes
