[Answered] Why is the consumption of Meat considered bad

I heard something to do with Nitrogen and …cow farts(?) I am really unsure of this and would like to learn more.

Answer -

4 Parts

  • Ethical reason for consuming animals
  • Methane produced by cows are a harmful greenhouse gas which is contributing to our current climate crisis
  • Health Reasons - there is convincing evidence that processed meats cause cancer
  • it takes a lot more calories of plant food to produce the calories we would consume from the meat.

    • Ethical reasons: hundreds of billions of animals are killed every year (not counting fish), after living a miserable and short life.
    • Environmental: greenhouse emissions (CO2 and methane), deforestation for pastures, water pollution, are all caused by animal agriculture. If everyone went vegan we'd need only 25% of the land we currently use for agriculture.
    • Health: there is some evidence that meat causes cancer, and convincing evidence that processed meat causes cancer. Also, the use of antibiotics for animals can lead to the development of antibiotic-resistant bacteria.

    Cow farts are methane, which are a more aggressive form of greenhouse gas, though with shorter lifespan.

    Here's more info about meat and the environment.

    • For the cancer risk, this is the pertinent info:

      An analysis of data from 10 studies estimated that every 50 gram portion of processed meat eaten daily increases the risk of colorectal cancer by about 18%.

      That's about half a hot dog. Seeing as the news isn't exploding, this means that this is relative risk. Meaning your current chances of getting colorectal cancer is X. Eating a hot dog every other day continuously multiples your chance by 1.18. American Cancer Society states that over their lifetime, 1 in 23 men (4.35%) of men will develop colorectal cancer. This means if you ate 1 hot dog every other day continuously, a man's odds of contracting colorectal cancer changes from 4.35% to 5.13% over their lifetime.

      • That's just for colorectal cancer. It also affects other types of cancer (like breast cancer) and increases the chance of dying from heart disease considerably.

  • I think everything has been addressed. I just wanted to clarify that the methane is from cow burps, not farts.

    • One other thing I think is worth mentioning: meat is good, but it’s not even that good. As a child I was a very picky eater and largely carnivorous, having to purposefully supplement the occasional vegetable. Now I’m essentially pescatarian because honestly, most meat isn’t really good. It can be low quality, bland, and boring. Innovative chefs seem to be realizing that, and I personally agree that Eleven Madison’s food is better now that it’s fully plant based.

      Meat can be such a crutch, and when it’s not, it requires quality cuts and good preparation. And yet many people would rather eat a tough, poorly seasoned mediocre steak than a vegan dish, even if it’s genuinely a bad experience, but I’m pretty sure it’s a misplaced pride thing.

      Finally, working with meat can be a lot harder than vegetables, especially chicken. Dominique Crenn has a wonderful cookbook featuring incredible plant based dishes, and of course Atelier Crenn is one of the most convincing arguments of plant superiority.

      I find that, for those who simply don’t care about the world around them, an appeal to taste and ease is far more effective than trying to introduce humanity. It also prevents the knee jerk reaction to plant based diets— “sure, I like my meats too, but it’s just too boring/doesn’t taste good enough” shifts the discussion from tribalistic hatred of vegans to something that directly impacts them, largely the only way to actually get some people to listen.

  • Because the amount of resources required to raise the livestock required to support the free market of meat is unsustainable. Also the impact of all that livestock is a huge contributor to climate change. So besides the moral argument of it being wrong to eat another living beings there is a very real danger to ourselves in the future.

  • The main issue is probably less meat itself than the ginormous quantities we consume.

    Most livestock farming is intensive, meaning they can't rely on grazing alone and need extra food sources, typically corn. They emit methane, a greenhousing gas on steroids.

    That grain is produced through very intensive agricultural methods because we can't get enough of it. It consumes ridiculously large amount of water and slowly degrades the soils. Nitrates eventually end up in the sea, causing algea to proliferate while other lifeforms are suffocated. See the dead zone in Mexico's gulf.

    71% of agriculture land in Europe is dedicated to livestock feeding.

    The percentage must be similar or higher in America, and don't count North America alone: without grains from Brazil, we're dead. Period. So next time you hear the world blaming Brazil for deforestation, keep in mind that a large share of it is to sustain livestocks...

    Cattle farming in the USA is heavily subsidized, by allowing farmers to use federal land for grazing for free (I believe something similar is in place in Canada?). The claim they "take care of the land" is absurd: nature has been doing that for millenias without needing any help. First nations have been living in these lands also without supersized cows herds and it was going alright. Farms actually prevent wildlife to take back its place.

    But I wouldn't blame them. People in North America (among others, and I live in Canada, definitely me too) eat indecent and unhealthy quantities of meat, and that has to come from somewhere.

    Now, simple math will tell you: if everyone in the world was consuming meat in the same quantities as us, there would'nt be enough suitable land on Earth to grow the corn that needs to go with it.

    Another thing is not all meats are equal in terms of pollution. From the worst to the least bad, in equivalent kgCO2 per kg of meat you can actually eat: -Veal: 37 -Chicken (intensive, in cage): 18 -Beef: 34 -Pork: 5--7 -Duck, rabbit, pork: 4--5 -Chicken ("traditonal, free range): 3--4 -Egg (for comparison): <2

    You can appreciate the orders of magnitude!

    There are only 2 ways out of this:

    • reduce meat consumption, and pick it right
    • grown meat (meat made without the animal around it, in machines)

    One can be done today, starting with your next meal. We don't need meat every meal, we don't even need meat every day, but it is true that going full vegetarian force a certain gymnastic to get all the nutriments one need.

    The other solution is barely getting there, so there are still unknown (food quality, resources consumption, etc.) and the economics may not help it taking off.

    The third (and let's face it: current approach at national level everywhere on this issue) option is to do nothing and keep going as if the problems didn't exist. This is guaranteeing a famine in the coming decades. When we'll fail to feed our livestock, and it will start dying, it will be too late to turn around and get the whole agriculture sector to transition. These things take many years.

    We're trying to reduce our meat consumption at home, or to favor the least impacting ones. We still eat too much meat, but I hope we can gradually improve.
