We slaughter about 80 billion animals every year to produce meat (excluding sea animals).
Even though the industry causes biodiversity loss, deforestation and depletes about 38.5% of the world’s arable land, meat consumption remains widespread.
Below, you will find out if there are any ethical arguments for eating meat and the most common justifications many people use to continue consuming animal products.
Most common arguments for eating meat:
1. Humans need meat
Many people argue that we can obtain many nutrients humans need from meat products. While that’s true, it is entirely possible to sustain yourself on a completely plant-based diet, too.
Two of the largest bodies of nutrition and diet professionals, the American Dietetic Association and the British Dietetic Association, have both stated that a well-planned vegan diet is nutritionally adequate and safe for all stages of life, including pregnancy.
We can get all the protein, iron, calcium, and other nutrients that we need by eating 100% plant-based. All it takes is being smarter about what we put on our plates.
Tofu and quinoa, for example, are complete proteins, which means they contain all nine essential amino acids. Other plant-based complete proteins include:
- Chia seed
Furthermore, eating rice and beans will give you all the needed amino acids since beans are low in methionine and high in lysine, while rice is low in lysine and high in methionine.
So you will get the best from both worlds when you put them together. Other great complete protein combinations include:
- Whole wheat toast and nut butter
- Lentil stew and whole-grain bread
- Spinach and sunflower seeds
Last but not least, vegans have lower BMIs (body mass index), and they tend to eat less cholesterol & saturated fat than omnivores and more fiber, vitamins, and minerals.
As a result, their blood cholesterol and blood pressure levels are usually lower, with reduced risk of heart disease, type 2 diabetes, stroke, obesity, and some type of cancer.
Plus, people on plant-based diets can easily take fortified foods or dietary supplements to ensure they get all their nutrients (such as B12).
2. Going vegan is expensive
Many people argue that going vegan is expensive. If you only shop from health stores and buy vegan yogurts, cheeses, and other “fancy” vegan foods, that can be true.
However, you can go vegan even if you are on a budget by following a few strategies:
- Purchase affordable staples for a healthy vegan diet like – grains, beans, legumes, seeds, and seasonal & local produce (veggies and fruits).
- Start cooking at home instead of buying from restaurants. This way, you can select simple, nutritious meals and find affordable ways to source ingredients.
- Buying in bulk can also significantly reduce the cost of products like oats, legumes, and rice.
3. Our ancestors ate meat
“Our ancestors ate meat” is another common argument people present to justify meat consumption. However, just because a practice was acceptable in the past doesn’t mean it’s adequate at present.
Our ancestors lived in a wildly different world than us; they ate meat out of necessity.
That’s not the case now. We have an abundance of options, and because of that, we can’t consider eating meat as an ethical action.
If the main argument for eating meat is “because our ancestors did it,” then why don’t we all stop using technology, start sleeping outside, speak in primitive language, or have incestuous experiences?
And it is ethical to base our morality on the actions of our ancestors, primitive beings that did many other unethical things such as murder, enslaving, and rape without consequence?
4. Animals are lesser beings & less intelligent than humans
Some people seem to believe that animals only operate on base instincts and are mindless creatures. Yet, many examples show the complete opposite of that.
- Elephants exercise creativity and use sticks to draw on the soil.
- Octopuses build little dens and use stones to create shields to protect the entrance. They have an excellent short and long-term memory and a remarkable ability to learn new skills.
- Dolphins are highly sociable creatures with a highly developed ability to adapt to their habitat. They help one another when injured or ill, and they’re able to pass on their knowledge to others.
Furthermore, many animals are a great help for humans in distress. For example, SymptomFind explains that we can train dogs and horses to provide companionship for people suffering from PTSD and OCD.
Pigs are intelligent and sensitive and can help autistic children stay calm. Goats and lambs, too, can be trained to ease anxiety and can be used for animal-assisted therapy.
But let’s consider that none of that was true. What exactly does intelligence have to do with the worth of life?
If intelligence equals dominance, does that mean that anyone with a high IQ can do what they want to someone with a lower IQ?
When you think about it, it doesn’t make a lot of sense to base ethical decisions on someone’s intelligence.
5. It is the food chain
The food chains within nature are essential. They help maintain healthy populations of animals and ensure that the natural ecology is in balance.
Additionally, the food chains in nature exist because the predator needs to kill the prey to survive. We don’t have to kill anyone to live.
The “food chain” argument allows us to slaughter trillions of animals every year under the illusion that it is a part of the natural world.
However, what we currently do to animals does not resemble anything like a food chain.
We selectively breed, artificially inseminate, mutilate and farm animals. Then we drive them to the slaughterhouse, to hang them upside down, to slice their throat, and to drain them of their blood.
Even if we are the most intelligent species, we have moral agency as humans. We can’t base our ethical decisions on what wild animals do (because of their necessity to survive).
The physical ability to enslave and exploit others doesn’t make it morally justifiable.
6. Plants feel pain
Plants are alive, and they can perform various activities at a cellular level and respond to stimuli. For example, they can tilt to face the sunlight or close over a fly, but that doesn’t mean they can feel pain.
A plant lacks the nervous system, pain receptors, and brain, which means anatomically, they can’t feel pain.
They do not conduct any activities at a conscious or cognitive level, and plants are not sentient.
Additionally, if someone truly cares about plants and their well-being, here are some quick facts:
- It takes up to 16 kilograms of plants to create 1 kilogram of animal flesh. So, many more plants are consumed for the production of animal products.
- Up to 91% of Amazon rainforest destruction is due to animal agriculture, meaning that millions of trees have been and continue to be destroyed because of the consumption of animal products.
So, if someone truly believes plants feel pain, they should consider ditching animal products, since animal factories cause a lot more harm to plants.
And lastly, if we focus on the ethics of the excuse, do you think that dropping broccoli into boiling water and boiling chickens alive is the same thing?
Arguments against eating meat
After looking at some common arguments people present to justify eating meat, let’s tackle some of the ways meat consumption causes harm. Here are a few reasons why it’s not ethical to eat meat:
1. Meat consumption creates abusive conditions for animals
As if slaughtering animals wasn’t bad enough, livestock farms and factories also place animals in horrific living conditions. Forget the image of cows grazing grass pastures.
Instead, many livestock animals are placed in cages and stall buildings in many farms, prohibited from seeing the outdoors.
Many of them are mutilated their whole lives. Chickens will have their beaks removed, cows and pigs will have their tails docked, and many males will be castrated without anesthesia. With their movement severely restricted, they can never express natural behaviors.
Animals can feel pain & other emotions and desires beyond avoiding hunger or death.
If it’s not about equity, then it’s about accountability. We have considerable power over the animals and our environment, and we are exercising it in a way that causes unnecessary harm.
As intelligent beings, we are obliged to set a higher standard of treatment for creatures with less power than us.
2. Meat farms create abusive conditions for human workers
It’s not just animals that get hurt. The meat industry is notorious for abusing workers; the animal factories usually hire low-income workers, or people from impoverished countries, taking advantage of the fact that they have limited job opportunities.
They often don’t give them defined working hours or offer zero-hour contracts with no overtime or sick pay. As a result, many can work for days and weeks without getting paid.
Factory farm workers routinely inhale hazardous levels of particulate matter and ammonia and hydrogen sulfide gases. They are also exposed to bacterias such as salmonella, E.coli, staph, etc.
Their job is dangerous, and they often struggle with chronic pain and severe injuries.
3. Meat consumption is terrible for the environment
The constant need for more land to create livestock farms is destroying existing animal habitats, and it also results in severe levels of deforestation and biodiversity loss.
To feed livestock and produce meat, farms consume high levels of water. And when livestock manure is not properly disposed of, waste contaminates watercourses and worsens water pollution.
Manure also releases methane into the atmosphere, worsening air pollution. Having unnaturally high populations of livestock also means releasing excess methane during digestion.
And when meat is processed, factories release vast amounts of greenhouse gasses.
These are just some of the issues with animal farming. You can find the 8 most significant environmental benefits of reducing meat consumption here.
The argument about meat consumption being natural to humans no longer holds water. Our ancestors might have eaten meat, but they existed under completely different circumstances.
In their time, the practice did not deplete or damage the resources of their environment. Nowadays, we can reduce the damage to our planet, while obtaining all the necessary nutrients from plant-based foods.
Lastly, if human beings are the most intelligent species, we should hold ourselves accountable for the welfare of animals and the environment, and we should collectively try to minimize the pain and damage to our planet.
