Argument: Survival of the fittest

It is natural for human beings to farm, kill, and eat other species. In the wild there is a brutal struggle for existence as is shown by Darwin’s On the Origin of the Species. [1] The fact that we humans have succeeded in that struggle by exploiting our natural environment means that we have a natural right over lower species. The concept of survival of the fittest may seem outdated but it is still the defining order of nature. In fact farming animals is much less brutal than the pain and hardship that animals inflict on each other naturally in the wild.

Candidate 1: "Human evolved as omnivores over thousands of years. Yet since the invention of farming there is no longer a need for us to be omnivores. Even if we wished to we could no longer collect, hunt and eat our food in the same way as our ancestors as we could not support the human population. We have outstripped the pace of our evolution and if we do not want to be turning ever more land over to farming we have get our food from the most efficient sources, which means being vegetarian."
Candidate 2: "The problems with fatigue, apathetic behaviour and concentration are mostly a result from a lack of iron in the diet. However as with any diet this is only a problem when not eating the right things, this regularly means that such iron deficiency can be a problem in the developing world where vegetarians have little choice – usually eating little else except what they grow, normally just cereals. “Although the iron stores of vegetarians are sometimes reduced, the incidence of iron-deficiency anaemia in vegetarians is not significantly different from that in the general population”, there are plenty of sources of iron that can be eaten by vegetarians such as legumes and whole grains that are a substantial part of most western vegetarian’s diets meaning it is not a problem. [1] Research done in Australia concludes that "There was no significant difference between mean daily iron intakes of vegetarians and omnivores". [2]

Candidate 3: "Being vegetarian helps the environment

Becoming a vegetarian is an environmentally friendly thing to do. Modern farming is one of the main sources of pollution in our rivers. Beef farming is one of the main causes of deforestation, and as long as people continue to buy fast food in their billions, there will be a financial incentive to continue cutting down trees to make room for cattle. Because of our desire to eat fish, our rivers and seas are being emptied of fish and many species are facing extinction. Energy resources are used up much more greedily by meat farming than my farming cereals, pulses etc. Eating meat and fish not only causes cruelty to animals, it causes serious harm to the environment and to biodiversity. For example consider Meat production related pollution and deforestation

At Toronto’s 1992 Royal Agricultural Winter Fair, Agriculture Canada displayed two contrasting statistics: “it takes four football fields of land (about 1.6 hectares) to feed each Canadian” and “one apple tree produces enough fruit to make 320 pies.” Think about it — a couple of apple trees and a few rows of wheat on a mere fraction of a hectare could produce enough food for one person! [1]

The 2006 U.N. Food and Agriculture Organization (FAO) report concluded that worldwide livestock farming generates 18% of the planet's greenhouse gas emissions — by comparison, all the world's cars, trains, planes and boats account for a combined 13% of greenhouse gas emissions. [2]

As a result of the above point producing meat damages the environment. The demand for meat drives deforestation. Daniel Cesar Avelino of Brazil's Federal Public Prosecution Office says “We know that the single biggest driver of deforestation in the Amazon is cattle.” This clearing of tropical rainforests such as the Amazon for agriculture is estimated to produce 17% of the world's greenhouse gas emissions. [3] Not only this but the production of meat takes a lot more energy than it ultimately gives us chicken meat production consumes energy in a 4:1 ratio to protein output; beef cattle production requires an energy input to protein output ratio of 54:1.

The same is true with water use due to the same phenomenon of meat being inefficient to produce in terms of the amount of grain needed to produce the same weight of meat, production requires a lot of water. Water is another scarce resource that we will soon not have enough of in various areas of the globe. Grain-fed beef production takes 100,000 liters of water for every kilogram of food. Raising broiler chickens takes 3,500 liters of water to make a kilogram of meat. In comparison, soybean production uses 2,000 liters for kilogram of food produced; rice, 1,912; wheat, 900; and potatoes, 500 liters. [4] This is while there are areas of the globe that have severe water shortages. With farming using up to 70 times more water than is used for domestic purposes: cooking and washing. A third of the population of the world is already suffering from a shortage of water. [5] Groundwater levels are falling all over the world and rivers are beginning to dry up. Already some of the biggest rivers such as China’s Yellow river do not reach the sea. [6]

With a rising population becoming vegetarian is the only responsible way to eat.

Candidate 4: "Vegetarianism is healthier

There are significant health benefits to 'going veggie'; a vegetarian diet contains high quantities of fibre, vitamins, and minerals, and is low in fat. (A vegan diet is even better since eggs and dairy products are high in cholesterol.) The risk of contracting many forms of cancer is increased by eating meat: in 1996 the American Cancer Society recommended that red meat should be excluded from the diet entirely. Eating meat also increases the risk of heart disease - vegetables contain no cholesterol, which can build up to cause blocked arteries in meat-eaters. An American study found out that: “that men in the highest quintile of red-meat consumption — those who ate about 5 oz. of red meat a day, roughly the equivalent of a small steak had a 31% higher risk of death over a 10-year period than men in the lowest-consumption quintile, who ate less than 1 oz. of red meat per day, or approximately three slices of corned beef.” [1] A vegetarian diet reduces the risk for chronic degenerative diseases such as obesity, high blood pressure, diabetes and types of cancer including colon, breast, stomach, and lung cancer because of it's low fat/cholesterol content. There are plenty of vegetarian sources of protein, such as beans and bean curd; and spinach is one of the best sources of iron.

Candidate 5: "It is immoral to kill animals

As evolved human beings it is our moral duty to inflict as little pain as possible for our survival. So if we do not need to inflict pain to animals in order to survive, we should not do it. Farm animals such as chickens, pigs, sheep, and cows are sentient living beings like us - they are our evolutionary cousins and like us they can feel pleasure and pain. The 18th century utilitarian philosopher Jeremy Bentham even believed that animal suffering was just as serious as human suffering and likened the idea of human superiority to racism. It is wrong to farm and kill these animals for food when we do not need to do so. The methods of farming and slaughter of these animals are often barbaric and cruel - even on supposedly 'free range' farms. [1] Ten billion animals were slaughtered for human consumption each year, stated PETA. And unlike the farms long time ago, where animals roamed freely, today, most animals are factory farmed: crammed into cages where they can barely move and fed a diet adulterated with pesticides and antibiotics. These animals spend their entire lives in their “prisoner cells” so small that they can't even turn around. Many suffer serious health problems and even death because they are selectively bred to grow or produce milk or eggs at a far greater rate than their bodies are capable of coping with. At the slaughterhouse, there were millions of others who are killed every year for food.

Further on Tom Regan explains that all duties regarding animals are indirect duties to one another from a philosophical point of view. He illustrates it with an analogy regarding children: “Children, for example, are unable to sign contracts and lack rights. But they are protected by the moral contract nonetheless because of the sentimental interests of others. So we have, then, duties involving these children, duties regarding them, but no duties to them. Our duties in their case are indirect duties to other human beings, usually their parents.” [2] With this he supports the theory that animals must be protected from suffering, as it is moral to protect any living being from suffering, not because we have a moral contract with them, but mainly due to respect of life and recognition of suffering itself.

Candidate 6: "Being vegetarian reduces risks of food poisoning

Almost all dangerous types of food poisoning are passed on through meat or eggs. So Campylobacter bacteria, the most common cause of food poisoning in England, are usually found in raw meat and poultry, unpasteurised milk and untreated water. Salmonella come from raw meat, poultry and dairy products and most cases of escherichia coli (E-Coli) food poisoning occur after eating undercooked beef or drinking unpasteurised milk. [1]

Close contact between humans and animals also leads to zoonosis – diseases such as bird ‘flu which can be passed on from animals to humans. Using animal brains in the processed feed for livestock led to BSE in cattle and to CJD in humans who ate beef from infected cows.

Candidate 7: "To suggest that battery farms are in some way 'natural' is absurd - they are unnatural and cruel. To eat meat is to perpetuate animal suffering on a huge scale - a larger, crueler, and more systematic scale than anything found in the wild. Furthermore, the very fact of humanity's 'superiority' over other animals means they have the reason and moral instinct to stop exploiting other species. If an alien species from another planet, much more intelligent and powerful than humans, came and colonized the earth and farmed (and force-fed) human beings in battery farm conditions we would think it was morally abhorrent. If this would be wrong, then is it not wrong for we 'superior' humans to farm 'lower' species on earth simply because of our ability to do so?"
