The Vegan vs. Omnivore Debate Part 1
90It's an On-Going Battle
This vegan vs. omnivore sparring is an ongoing debate that seems to have no end in sight. You can see this debate happening lots on many discussion boards on the web, as well as people (like me) posting their opinions about whether veganism or omnivorism is better and why. Most vegans I've sparred with base their arguments on their emotions and reports of little value, with mostly improper research to back them up. There are many omnivores out there that also cannot have enough gumption to come back with better research and evidence to fight against the claims that put a bad light on omnivores, not to mention animal agriculture itself.
There are three main things that vegans and omnivores clash over: green house gas emissions, animal agricultural practices, and the digestive tract in humans. And all three of these topics have been discussed over and over again, to the point where I kinda get tired of them, but I would like to shed some light on the facts behind the claims in a multi-part series.
Greenhouse Gass Emissions from Livestock: Is it as Big a Deal as People Make it Out to Be?
I was asked a while ago about beef being a major cause of global warming since, "cows' methane emissions are neck-and-neck with carbon emissions at cooking Mother Earth?" And, "If everyone on earth became vegetarian, decreasing the demand for gas-producing cattle, would that help?" Ever since I read Livestock's Long Shadow, and some reviews of what the FAO had to say about livestock methane and carbon emissions, including one from one of my favorite hubbers, I have come up with my own conclusions.
If you see Table 3.12 in Chapter 3 in Livestock's Long Shadow (Section 3.4: Summary of Livestock's Impact) on page 113, you will notice that this chart summarizes all that has been said in the previous sections of that chapter. Now I have done some calculations on the methane portion of the chart (as well as the other two GHG's), and have come up with an answer that strongly disproves the claim made by the first quote above: Of the Grand Total Anthropogenic (human activities) GHG emissions, which is 40 billion tonnes of CO2 equivalent, methane emissions from livestock only contribute to 5.5% of that grand total. According to the table, total methane emissions from livestock (enteric fermentation and manure management) accounts for only 2.2 billion tonnes CO2 equivalent, whereas total anthropogenic methane emissions comprises of 5.9 billion tonnes of the grand total (14.75% methane contribution). That is a HUGE difference, far from being equal with total carbon emissions. Speaking of which, CO2 emissions from livestock only contribute to 0.4% of the grand total of anthropogenic emissions. Total anthropogenic CO2 emissions, on the other hand, is 31 billion tonnes, which contributes to 77.5% of all CO2 emissions. Well, the person who said that should be eating their words by now.
It is obvious from above that people make a big deal out of something so trivial. Going vegan simply because of misinformation, or fictional facts that are made to make the animal agricultural industry a sinful thing, including effects on global warming, is like trying to become a farmer simply because of the misconception that country life so much more peaceful and quieter than the big city. Those things, in themselves, are absolutely laughable! One has to get his facts straight before he gets into an argument, otherwise it's going to come back and bite him in the ass. Or her. And, getting emotionally involved doesn't help matters either. This is where a lot of brainwashing happens, as people nowadays tend to put their emotions first before the facts.
Now for the second quote, I had already written a response to that and I would like to post it again here:
"...it has many variables and is a very complex question, unable to be simply answered by a yes or a no.
"If everyone became vegetarian thus decreasing the demand for gas-producing livestock (not just cattle), it would and it wouldn't help.
"The reason it might help is economics. Less demand for red meat and dairy products, the less supply there needed in the market. Less supply means less cattle are being raised for slaughter and dairy production, thus reducing methane emissions. Less cattle also opens up land that had been used for forage production to be used for vegetable and crop production instead.
"But in reality, it is not that simple. Thus the "no" part. There are large tracts of land that cannot be used for producing crops and vegetables, but instead are much better suited to raising cattle, sheep, goats and other livestock. There happens to be much more of this type of land than the land available for crop production. Also, the land that is also great for producing fruits, vegetables and grains is also great for cities and towns to expand on. There has been a fierce war going on over this for a very long time. Only in a realistic world would it have no variation in soil type nor topography so that all crops can be grown on all land, which seems to be stuck in many a vegan's mind when it comes to fighting against animal agriculture of any sort (no offence).
"The second part of the argument is the fact that we humans are not biologically built as herbivores as ruminants are. We have digestive tracts very similar to pigs and bears, which are omnivores. Thus, this limitation also limits the parts of plants that we can eat. Lets take corn as an example. We can only eat 5% of the corn plant: the kernels, and this has to be at the right stage of growth. We cannot eat the corn plant during any of it's growth stages. A herbivore can and will happily do so. The same goes for other cereal grains including wheat, barley, oats, rye, canola, peas, beans, etc. We also cannot eat all parts of vegetables either: potatoes, tomatoes, carrots, celery, cauliflower, broccoli, etc. Though there is a method of producing "green manure" through composting plant matter, this does not produce the nutrients nor faster break-down of plant matter into manure than through the gut of a herbivore. This is the more efficient and economical means of using plant matter, especially the parts and types of plants that we do not nor cannot eat. According to my previous argument, since there is only a small percentage of land that can be used for crop production, grass and legumes are able to grow on the rest of the land that is not useable for crop production. The only way to "harvest" these tough plants is to either have livestock graze in those areas, or form larger wildlife habitats on that type of land.
"My third reason for not agreeing to the world-wide switch to veganism is water. If you think livestock "waste" so much water, you should see how much water we humans waste on a daily basis. We do not use water simply to drink it or to put into food production, but we also use it to water our pretty lil' lawns, for large industrial purposes from oil and gas to construction, to mix with fluids for many purpose other than personal consumption. Livestock only use water to drink it and cool themselves in. Pets only use water to drink and cool and bath in. Less livestock means more excuse for the corporate companies to waste it.
"Fourthly, is we have relied on the use of animals for as long as we started finding other means of using parts of the animal that we don't eat. And this has expanded greatly to the point were the general population don't even realize it. If the population of livestock decreased, we would have to find other means of making our tires work and wear like they do, our cosmetics as nice as they are, our mattresses, chairs, couches, love seats etc. have the lovely comfy fabric and parts to them like they are, among many other things.
"If we lessened our consumption of livestock purely on the fact that they produce too many farts and burps that harm our atmosphere, then we must have completely lost our minds. There are many other things we can do to decrease the production of methane from cattle than just stopping eating them.
As you can see, this issue with greenhouse gas emissions and the livestock industry shouldn't be made such a big deal out of. There are more important things to worry about right now.

i never realized it was a big deal. as far as i know humans are evolutionarily omnivores and there are several key nutrients that we need that are only found in meat. particularly b vitamins which are not digested properly as pills taken by vegans.
but i look at it this way if I'm in that line at McDonald's and i don't eat that burger, the guy behind me is gonna
im doing a persuasive essay on vegans vs. omnivores and im having trouble finding sources
im not sure this really helped
Thanks. Thats really going to help me on my essay!
Could you tell me the actual URL of the website?
to me veganism does not solve the problem instead it just hides it. A true solution would be to reduce animal methane and co2 using science
You've got to be kidding me. How are you extrapolating these numbers? A quick search reveals that the numbers you've posted are completely false. Check the EPA's website: http://www.epa.gov/rlep/faq.html for example. Livestock methane contributes 20% of the total methane gas production in the U.S. (28% globally).
You're having trouble being unbiased in your post because you have ties with cattle (I'm assuming a cattle farmer), so it's not surprise that this is very much one sided.
You can't deny the effect factory farms and the raising of livestock for food production has on the planet. Unless, of course, you have some sort of vested interest in it. From the methane gas production, to water contamination from seeping waste, to wasted resources and used up aerated land caused by growing the feed required for all of these animals. You would have to be blind to deny all of this.
Stop trying to located sources to support your confirmation bias and open your knowledge base to some new information. I know information that contradicts your theories may be hard to digest, but just because it's contradictory, doesn't make it wrong.
Also, some sources below for your viewing pleasure.

Look buddy, I applaud you for not crowding cattle in a pen all day and letting them roam like nature "intended them to". That's great and all, and from what it seems, that is not what's causing an environmental impact from livestock ranching. The problem stems from what I call "factory farming" (in quotes because it's not a term I made up, but a serious problem in the U.S.). It's an overproduction of meat that this country/world does not need. That is where this waste comes from.
"...HUMAN waste is a much bigger contributor to water contamination???" Ok bud, nowhere in my comment did I say this is NOT a problem. First: How much bigger issue is it than factory farming waste? Second: Water contamination needs to be controlled, regardless of where it comes from. Not eating meat is one way to REDUCE water pollution. It won't eliminate it, no, because of the human factor of course, but we have to start somewhere.
Your whole attack on vegetarianism is unbelievable. Especially when you compare it to a religious cult in a latter post. The best part about this whole thing is that you call it a "debate", but you only present one side of the argument. Last time I checked, that's not called a debate, but rather a preaching.
Also, if you're arguing with EPA's numbers then that is on you my friend. I am not an environmental scientist, but I somehow doubt the EPA is trying to deceive us. It seems like you're onto some sort of conspiracy theory here. The EPA report clearly says that the 20% of methane come from livestock.
One of the points of vegetarianism is to reduce the carbon footprint and leave the planet in a "usable" shape for future generations. Every piece of evidence shows this to be supported. For you to rip into vegetarians and to have this debate about it shows that you truly have an ulterior motive in this fight. How does someone argue against somebody's actions that are aimed at improving the lives of others (confined animals, affected humans, etc...) when these actions don't harm anyone else, and have been shown to be effective?
I'm just going to leave this here because I don't want to spend a lot of times going into the details: https://secure.wikimedia.org/wikipedia/en/wiki/Env
It has many sources to peer-reviewed journals and studies. The scientific community unequivocally agrees that meat production harms the environment. If you want to doubt that, that's obviously your prerogative.
We all think we're climate scientists, but few of us actually listen to the real climate scientists.
It's clear nothing will change your mind on the pure and simple fact that producing crops is much more economical than raising animals purely for food production (those animals require lots of crops too).
Look, I agree with you that extreme situations can be wrong under many circumstances, but in order to adapt to new ways of life people have to be able to change from conventional thinking and conventional ways of doing things.
I don't have to be an expert on farming to be informed about the environmental effects of the livestock sector. You are obviously very well informed about farming, and are also well informed about your side of the argument. Which is precisely why you fail to see (or believe) the research that has been done in response to your proclamations.
You appear to refer to me as some unscrupulous consumer of advertisement propaganda, who needs to stop paying attention to "PETA and HSUS". The ironic part of this accusation is that it shows your ignorance, since the issues of PETA and HSUS have nothing to do with the environment but are rather ethical instead.
Again, you can argue with the many climate experts and scientists about livestock's effect on the environment if you want to. I'm sure that your expertise as a long time and experienced farmer is comparable to their expertise in environmental science.
Look I'm not trying to get you to change your views, nor do I want to argue with you. I really do not think you're ignorant. I've stated that I think you're well informed in your field of expertise, and I don't question that.
I understand that we have some things in common (like views on factory farming), I'm not ignoring this part. To kind of answer you question in the post above, what really gets me going about your position is that your whole view unfairly disparages vegans. This article you are writing makes them seem like evil beings who are doing more harm than good. And the evidence you're using is questionable at best.
Look, I'm not trying to be abrasive and deride you for your beliefs. But, even if we decide to doubt the scientific research, those who are vegans are still doing more harm than good.
This article, and frankly this whole debate whenever it comes up, is nothing but an inquisition against meat non-eaters. All the evidence points to saying eating meat does more good than harm, how much "more good" is it, well that's not exactly quantifiable. There is no need to get out the pitchforks when someone chooses not to consume animal products.
And just to be clear, raising cattle and using livestock for the support of humans is not what I (or most vegans) have a problem with. It's the way that it's presently done that is the problem.
3rd paragraphs should have said:
Look, I'm not trying to be abrasive and deride you for your beliefs. But, even if we decide to doubt the scientific research, those who are vegans are still doing more GOD than HARM.

Hi - I really enjoyed reading all of your articles on omnovore -vegan debate. I am an animal scientist in Australia and we are working on ways to reduce methane from ruminants, like breeding for those that genetically rpoduce less or my particular one - plant bioactives and how they can inhibit methane-producing microbes in the rumen (and also do ther good stuff like control lactic acidosis). These plant bioactives are present in many plants - even in your favourite one, wild rose, but we only have looked into Australian native plants, Europeans have looked at their plants, but not much is happening in America - so maybe you can go and snoop around a bit about this. Anyway best luck in your work!
