A vegetarian diet is to be preferred over an omnivorous diet

Response to your round 1:You are committing an Argumentum ad Naturam fallacy because you are arguing that a vegetarian diet is bad as it is "not even natural".You are committing a Strawman Fallacy because you are vastly distorting, exaggerating and misrepresenting my view. I clearly stated that this debate will be about a whether "a well-balanced vegetarian diet is generally to be preferred over a well-balanced omnivorous diet." therefore your claims that "Meat contains certain ingredients which simply cannot be found in a stick of celery." and "One cannot subsist on legumes alone." are irrelevant and misrepresenting my view as I've never claimed that a celery-only or legume-only diet are to be preferred over an omnivorous diet.Furthermore, it is the position of the American Dietetic Association that appropriately planned vegetarian diets are healthful and nutritionally adequate [14].My first round:In this debate, I will be arguing that a vegetarian diet is to be preferred over an omnivorous diet as it is healthier, has a less significant negative impact on the environment and reduces the suffering and death of sentient lifeforms.----------------------------------------------------------------------------------------------------------------------A vegetarian diet is healthier than an omnivorous diet:In a 1988 report, it was found that there is a significant positive association between meat consumption and mortality because of all causes of death combined, coronary heart disease, and diabetes. [1]In another 2007 study, it was found that there is a significant positive association between red and processed meat intake and risk of cancer of the colon and rectum, esophagus, liver, lung, and pancreas [2].In a 2003 meta-analysis, it was concluded that long-term (≥ 2 decades) adherence to a vegetarian diet can lead to a significant 3.6-year increase in life expectancy [3].As it can reasonably be assumed that everyone would generally prefer not to have cancer in one’s rectum (or anywhere else), cardiovascular disease, and diabetes, it can be concluded that a vegetarian diet is to be preferred over an omnivorous diet as it is generally healthier, leads to a higher life expectancy and reduces one’s chances of getting cancer in one’s rectum.----------------------------------------------------------------------------------------------------------------------A vegetarian diet has a less significant negative impact on the environment:According to a 2017 study, livestock farming is responsible for at least 14.5% of greenhouse gas (GHG) emissions and is estimated to be responsible for at least 51% of global GHG emissions “based on the most complete and comprehensive analysis of all factors associated with livestock products (including emissions from the animals themselves and lost carbon sequestration from land clearing for feed production) estimates the sector's contribution to be at least 51 per cent of total global GHG emissions” [4],[5]. It is important to note, however, that even 14.5% is more than emissions from all transport combined [6].The chairman of the UN's Intergovernmental Panel on Climate Change, Dr Rajendra Pachauri, has described eating less meat as "the most attractive opportunity" for making immediate positive changes to climate change [7].As it can reasonably be assumed that people generally have no intention of harming the environment and would prefer having a less significant influence on climate change, it can be concluded that a vegetarian diet is to be preferred over an omnivorous diet.----------------------------------------------------------------------------------------------------------------------A vegetarian diet reduces the suffering and deaths of sentient lifeforms:In the same way that it is immoral to torture a cat (or any other animal) for the sake of viewing pleasure, it is immoral to eat a cat (or any other animal) for the sake of tasting its flesh. [16]Mylan Engel’s argument against eating meat [15]:(p1) Other things being equal, a world with less pain and suffering is better than a world with more pain and suffering.(p2) A world with less unnecessary suffering (suffering which serves no greater, outweighing justifying good) is better than a world with more unnecessary suffering.(p3) Even a minimally decent person (a person who does the very minimum required by morality and no more) would take steps to help reduce the amount of unnecessary pain and suffering in the world, if they could do so with very little effort.(p4) Many nonhuman animals (certainly all vertebrates) are capable of feeling pain [9].(p5) Animals in the meat industry are suffering [10],[11],[12],[13].(p6) Refraining from eating meat and eating something else instead requires very little effort [14].(c) We ought to stop purchasing and consuming meat.----------------------------------------------------------------------------------------------------------------------Overall, it can be concluded that a vegetarian diet is to be preferred over an omnivorous diet as it is generally healthier, better for the environment and because the extended suffering animals endure outweigh the short pleasure of eating meat.----------------------------------------------------------------------------------------------------------------------Sources:[1]: The American Journal of Clinical Nutrition, Volume 48, Issue 3, 1 September 1988, Pages 739–748,https://doi.org...[2]: Genkinger JM, Koushik A (2007) Meat Consumption and Cancer Risk.
