We millennials are often described as lazy, entitled and unwilling to leave our parents’ homes. But this isn’t the truth, nor is it what I’m here to discuss. We need to talk about what we’re eating and how it affects the world, our health and the countless animals at factory farms.
While it’s great that so many of us care, it’s important that we all understand the negative impact that eating meat, dairy and eggs has on the world.
Let’s start with the environment. It’s clear that killing animals for food is killing our planet. Consider this: Raising animals for food produces more greenhouse gas emissions than all forms of transportation combined. Simply by avoiding animal products, we can cut our carbon footprints in half.
Animal agriculture isn’t only a leading cause of climate change; it’s also a leading source of water pollution. And it’s a huge drain on natural resources—for example, a pound of beef requires 13 percent more fossil fuel and 15 times more water to produce than a pound of soy. If you say you care about the environment, it’s time to put your money where your mouth is and eat a plant-based diet.
Millennials are the age group most likely to be uninsured, so it’s important we discuss the negative health effects of consuming animal products. Study after study has shown that one of the best ways to improve your health is to adopt a vegan diet. In fact, researchers at the Mayo Clinic found that compared to shorter-term vegetarians, people on a vegetarian diet for more than 17 years enjoyed a 3.6-year increase in life expectancy. Just think about all you could do with that extra time.
But surely the most important reason we millennials need to start caring about what we eat is because it directly affects the lives of billions of farmed animals. Cows, pigs and chickens raised and killed for food are just as smart and sensitive as the dogs and cats we adore at home. But at factory farms, they’re subjected to extreme confinement, brutal mutilations and bloody, violent deaths.
Fortunately, we have the power to stop this. We can help the planet, animals and ourselves simply by adopting a vegan diet. And I know what you’re thinking—yes, you can still enjoy brunch.
So what do you say, fellow millennials? Let’s be the generation that puts an end to this cruel and unnecessary industry and makes the world a kinder place for all.
I wish to preface this post by stating that the references made to the Australian Bush Meat trade in this post are only included as a condition of republishing this material as I feel the rest of the article has merit. I do not condone or support the commercial Bush Meat trade in any way and I encourage all readers to do the same.
Being vegetarian saves cows' lives, but threatens the future of other sentient creatures.nunro
The ethics of eating red meat have been grilled recently by critics who question its consequences for environmental health and animal welfare. But if you want to minimise animal suffering and promote more sustainable agriculture, adopting a vegetarian diet might be the worst possible thing you could do.
Renowned ethicist Peter Singersays if there is a range of ways of feeding ourselves, we should choose the way that causes the least unnecessary harm to animals. Most animal rights advocates say this means we should eat plants rather than animals.
It takes somewhere between two to ten kilos of plants, depending on the type of plants involved, to produce one kilo of animal. Given the limited amount of productive land in the world, it would seem to some to make more sense to focus our culinary attentions on plants, because we would arguably get more energy per hectare for human consumption. Theoretically this should also mean fewer sentient animals would be killed to feed the ravenous appetites of ever more humans.
But before scratching rangelands-produced red meat off the “good to eat†list for ethical or environmental reasons, let’s test these presumptions.
Published figures suggest that, in Australia, producing wheat and other grains results in:
at least 25 times more sentient animals being killed per kilogram of useable protein
more environmental damage, and
a great deal more animal cruelty than does farming red meat.
How is this possible?
Agriculture to produce wheat, rice and pulses requires clear-felling native vegetation. That act alone results in the deaths of thousands of Australian animals and plants per hectare. Since Europeans arrived on this continent we have lost more than half of Australia’s unique native vegetation, mostly to increase production of monocultures of introduced species for human consumption.
Most of Australia’s arable land is already in use. If more Australians want their nutritional needs to be met by plants, our arable land will need to be even more intensely farmed. This will require a net increase in the use of fertilisers, herbicides, pesticides and other threats to biodiversity and environmental health. Or, if existing laws are changed, more native vegetation could be cleared for agriculture (an area the size of Victoria plus Tasmania would be needed to produce the additional amount of plant-based food required).

Grazing occurs on primarily native ecosystems. These have and maintain far higher levels of native biodiversity than croplands. The rangelands can’t be used to produce crops, so production of meat here doesn’t limit production of plant foods. Grazing is the only way humans can get substantial nutrients from 70% of the continent.
In some cases rangelands have been substantially altered to increase the percentage of stock-friendly plants. Grazing can also cause significant damage such as soil loss and erosion. But it doesn’t result in the native ecosystem “blitzkrieg†required to grow crops.
This environmental damage is causing some well-known environmentalists to question their own preconceptions. British environmental advocate George Monbiot, for example, publicly converted from vegan to omnivore after reading Simon Fairlie’s expose about meat’s sustainability. And environmental activist Lierre Keith documented the awesome damage to global environments involved in producing plant foods for human consumption.
In Australia we can also meet part of our protein needs using sustainably wild-harvested kangaroo meat. Unlike introduced meat animals, they don’t damage native biodiversity. They are soft-footed, low methane-producing and have relatively low water requirements. They also produce an exceptionally healthy low-fat meat.
In Australia 70% of the beef produced for human consumption comes from animals raised on grazing lands with very little or no grain supplements. At any time, only 2% of Australia’s national herd of cattle are eating grains in feed lots; the other 98% are raised on and feeding on grass. Two-thirds of cattle slaughtered in Australia feed solely on pasture.
To produce protein from grazing beef, cattle are killed. One death delivers (on average, across Australia’s grazing lands) a carcass of about 288 kilograms. This is approximately 68% boneless meat which, at 23% protein equals 45kg of protein per animal killed. This means 2.2 animals killed for each 100kg of useable animal protein produced.
Producing protein from wheat means ploughing pasture land and planting it with seed. Anyone who has sat on a ploughing tractor knows the predatory birds that follow you all day are not there because they have nothing better to do. Ploughing and harvesting kill small mammals, snakes, lizards and other animals in vast numbers. In addition, millions of mice are poisoned in grain storage facilities every year.
However, the largest and best-researched loss of sentient life is the poisoning of mice during plagues.
At least 100 mice are killed per hectare per year (500/4 × 0.8) to grow grain. Average yields are about 1.4 tonnes of wheat/hectare; 13% of the wheat is usable protein. Therefore, at least 55 sentient animals die to produce 100kg of usable plant protein: 25 times more than for the same amount of rangelands beef.
Some of this grain is used to “finish†beef cattle in feed lots (some is food for dairy cattle, pigs and poultry), but it is still the case that many more sentient lives are sacrificed to produce usable protein from grains than from rangelands cattle.
There is a further issue to consider here: the question of sentience – the capacity to feel, perceive or be conscious.
You might not think the billions of insects and spiders killed by grain production are sentient, though they perceive and respond to the world around them. You may dismiss snakes and lizards as cold-blooded creatures incapable of sentience, though they form pair bonds and care for their young. But what about mice?
Mice are far more sentient than we thought. They sing complex, personalised love songs to each other that get more complex over time. Singing of any kind is a rare behaviour among mammals, previously known only to occur in whales, bats and humans.
Girl mice, like swooning human teenagers, try to get close to a skilled crooner. Now researchers are trying to determine whether song innovations are genetically programmed or or whether mice learn to vary their songs as they mature.
“Hoping to prepare them for an ethical oversightâ€Nikkita Archer
Baby mice left in the nest sing to their mothers — a kind of crying song to call them back. For every female killed by the poisons we administer, on average five to six totally dependent baby mice will, despite singing their hearts out to call their mothers back home, inevitably die of starvation, dehydration or predation.
When cattle, kangaroos and other meat animals are harvested they are killed instantly. Mice die a slow and very painful death from poisons. From a welfare point of view, these methods are among the least acceptable modes of killing. Although joeys are sometimes killed or left to fend for themselves, only 30% of kangaroos shot are females, only some of which will have young (the industry’s code of practice says shooters should avoid shooting females with dependent young). However, many times this number of dependent baby mice are left to die when we deliberately poison their mothers by the millions.
Replacing red meat with grain products leads to many more sentient animal deaths, far greater animal suffering and significantly more environmental degradation. Protein obtained from grazing livestock costs far fewer lives per kilogram: it is a more humane, ethical and environmentally-friendly dietary option.
So, what does a hungry human do? Our teeth and digestive system are adapted for omnivory. But we are now challenged to think about philosophical issues. We worry about the ethics involved in killing grazing animals and wonder if there are other more humane ways of obtaining adequate nutrients.
Relying on grains and pulses brings destruction of native ecosystems, significant threats to native species and at least 25 times more deaths of sentient animals per kilogram of food. Most of these animals sing love songs to each other, until we inhumanely mass-slaughter them.
Former Justice of the High Court, the Hon. Michael Kirby, wrote that:
“In our shared sentience, human beings are intimately connected with other animals. Endowed with reason and speech, we are uniquely empowered to make ethical decisions and to unite for social change on behalf of others that have no voice. Exploited animals cannot protest about their treatment or demand a better life. They are entirely at our mercy. So every decision of animal welfare, whether in Parliament or the supermarket, presents us with a profound test of moral characterâ€.
We now know the mice have a voice, but we haven’t been listening.
The challenge for the ethical eater is to choose the diet that causes the least deaths and environmental damage. There would appear to be far more ethical support for an omnivorous diet that includes rangeland-grown red meat and even more support for one that includes sustainably wild-harvested kangaroo.
