The next frontier will be meat consumption. Particularly red meat.

A single 1/4 beef hamburger emits 7-12 kg of carbon[1]. Compared to ~1.5kg of carbon driving your car 3 miles[2].

Not telling you to go full vegetarian, but I'm personally far less interested in a beef product unless you're going to guarantee its an extremely expert prepared steak. Most beef is mediocre.

Yeah, plus the ethical angle. It's a bit ridiculous that we have people researching the 'theoretical ethical treatment of LLMs' when we are doing such awful things to animals on a massive scale.

We have dogs and cats as pets and we eat cows and pigs (in Western countries). As if cows and pigs didn't also have personalities, memories, parental bonds, the ability to feel pain. It's a mass wilful ignorance.

What's the difference between us and animals? I would argue that it's our ability to take ethical decisions and not inflict suffering even if it goes against our base instincts.

Where do you draw the line though? Because plants themselves (DNA-beings) are also alive.

Unless you decide to go on a full mineral diet.

alpineman 14 minutes ago | parent [-]

It's not about being alive, it's about having emotions and the ability to feel pain.

Plants don't cry out for days when their children are taken away from them. Plants don't remember your face, come up to you and want attention. Plants don't scream when they are killed (no matter what some edgy research shows).

Or to put it more simply, would you feel bad pulling a plant out the ground? I would imagine probably not. Would you feel bad pulling the lever and watching as a pig is lowered into a gas chamber? Or while slitting a cow's throat? I would imagine probably yes (hence why slaughterhouse employees have so many mental health issues and there is such high turnover).

Beef is already too expensive for most people. Americans are probably the exception but I can assure you that most Europeans do not have beef heavy diets. Even culturally, pork (and now chicken) were the proteins of choice.

Beef is too expensive for many Europeans because GDP per capita/standards of living are declining in many European countries. People in East Asia, the Middle East, Oceania and South America still eat plenty of beef too.

grunder_advice 28 minutes ago | parent [-]

That is true, however beef was always somewhat of a luxury in many European regions, simpily due to geography and population density. We don't have a lot of cheap grazing land to raise cattle on. And if you have cattle it's typically more economical to use them for diary than meat.

Yeah, since COVID and then the Nord Stream terror act they raised beef prices to unsustainable levels. Döner (which is cheap ground sausage like beef in practice) between 7 and 10 EUR now (was between 3,50 and 4). Blockhouse steak (tiny) is 48 EUR.

Going vegetarian would only cut it if you stayed clear of dairy. Gram for gram it's better to eat chicken than cheese for the climate.

softwaredoug 35 minutes ago | parent | next [-]

My research seems to indicate its about on-par with chicken. IE a chicken filet is about the carbon impact of 8oz of milk.

And it seems here its about 1/4 carbon per kg of food as beef:

They said cheese not milk. Note that it takes more than 1 unit of milk to produce 1 unit of cheese. From this source I found, they estimate ~10 input units of milk per output unit of cheese [1].

Assuming both of these is true, and assuming that the cheese making process produces no carbon, then a chicken filet would have the same carbon impact as .8oz of cheese or roughly a single slice of cheese.

The cheese making process does produce carbon (e.g. heating the milk) but it also produces whey as a valuable byproduct.

I switched to fortified soy milk and haven't looked back. Milk is tasty but soy has less sugar as well and now I prefer it. Cheese is harder to make a substitute but eating it 1-2 per year satisfies my craving.

Wait, how does beef emit carbon? I thought the main problem with beef was methane, not carbon emissions.

Ah, I see, your graph says CO2-equivalent, not CO2. It's the methane.

parineum 27 minutes ago | parent [-]

It's the infrastructure required to create a pound of beef, including the farmed grains.

stavros 26 minutes ago | parent [-]

I don't think it is, I think it's the methane, which is by far the largest greenhouse gas contributor in the process. Besides, the other emissions go away once your energy production is renewables.

The next frontier should be preventing forest fires. This is just Canada, imagine if we could prevent them around the world.

Forests burn and grow back. Healthy forests (not poorly-managed monoculture) are carbon-neutral on human timescales.

There's tens of millions of well-armed Americans who'd rather die fighting then let anyone take away their right to eat red meat, so good luck trying.

It’s more effective to convince people 95% of beef is very mid. So you’re not missing anything

I would never argue for banning red meat as it will certainly backfire and end up counterproductive.

markvdb 6 minutes ago | parent | prev [-]

To state the obvious, it's not about taking away the right to eat red meat, right? It's about trying to convince people to adopt a diet that is:

- healthier

- tasty

- cheaper

- a small contribution to keeping the planet livable for their children

- as a sign of respect for $DEITY/the planet/...

Many people will see some sense in at least one of the above arguments at one point in life.

The world is burning becuase people like you tell normal people they have to eat bugs and lentils and anything else is basically being hitler.

Why do you think outside of the coffee shops of the large metropolises people aren't

Rather than saying "hey shift your car to electric as its cheaper and more powerful and less smoke in your neighbourhood", it's "you need to stop consuming energy"

Rather than saying "support that local solar plant rather than growing ethanol", it's "stop eating meat otherwise you kill the planet"

Rather than saying "hey maybe we should get rid of oil so we're not reliant on fragile international supply chains, here's how we can make fertiliser from thin air" it's "you shouldn't drink milk"

jmyeet 41 minutes ago | parent | prev | next [-]

I question the methodology of that 100kg (per kg) figure for beef, for several reasons:

1. It's not the true Carbon or CO2 figure. It's weighted for other greenhouse gases. That's kind of an issue because methane naturally breaks down (into CO2 and water) over time. The methane issue comes up all the time in such estimates (eg leaks in natural gas pipelines) where methane is a worse greenhouse gas but temporary (7-12 years) and CO2 is essentially forever (until sequestration or photosynthesis);

2. Production method really matters here. American beef, for example, is primarily grain fed. That grain requires fertilizer (more natural gas) and distribution. Australian beef, for example, is largely fed on natural grasses and vegetation, typically until the last 60-120 days where it's transitioned to grain for marbling. American cattle is also heavily fed on corn, which really shouldn't exist in the quantities it does;

3. Ecosystems are complex. One of the big causes of the dust bowl, for example, was the destruction of the great bison herds. Replacing the natural grasses with crops like wheat was just the last straw. The point of the bison is that they're heavy, like up to 2000+ lb heavy, and they leave deep hoof prints on the plains. Water collects there when it rains and feeds cgrasses and the aquifers.

This has been backed up elsewhere too. China has had long projects to stop the desertification of the Gobi and spent a ton on planting trees with varied successes. You know what did work? Horses. They released horses and the same thing happened. Horse hoof prints allowed water to collect and grasses to grow and spread. Grasses, as it turned out, were key to stopping desertification, not trees.

So the point is that certain ecosystems need large herd herbivores to survive. So if you got rid of cattle entirely, what other second order effects would there be?

More practically, people just arne't going to give up meat. Sorry. Unless it become sprice prohibitve (as beef arguably is rapidly becoming now).

softwaredoug 28 minutes ago | parent | next [-]

On the ecological point, the difference is whether the grassland would naturally support that number of bison. Or if bison (or cows) are continually being grown, killed, grown killed at industrial scale beyond the normal bison lifecycle. With many carbon inputs (fossil-fuel based fertilizer, etc) and production costs (slaughtering, transport, etc).

Wild bison live 15-20 years.

Cattle raised for beef ~18 months.

That's beyond the natural carbon cycle an existing ruminant population.

Also horses, in my reading of the data, actually have less of a methane impact. They have a different digestive system entirely.

On the methane point, methane, yes, is a greenhouse gas that breaks down over years (~12 years). But has far worse impact on climate while its in the atmosphere.

quantumwannabe 32 minutes ago | parent | prev [-]

It’s completely made up. All meat is carbon neutral because animals don’t produce carbon atoms from nothing. They get them from the plants they eat which in turn get their carbon from the atmosphere.

The carbon cycle is basic scientific fact yet confidently ignored by people who hate things like logging and meat.

anticorporate 17 minutes ago | parent [-]

By that same logic, fossil fuels are carbon neutral because they come from living things.

The problem is we have too much carbon dioxide in the atmosphere, not too much of various assorted carbon-based compounds on the planet.

quantumwannabe 6 minutes ago | parent [-]

But the supply of herd animals is essentially fixed. There isn’t infinite growth. Eating meat therefore does not increase the amount of CO2 in the atmosphere, no matter what vegans who want to ban meat for personal moral reasons assert.

If humans stopped eating meat, the only way to reduce the amount of carbon that animals “emit” would be to kill all of them and bury their carcasses underground where they can’t decompose (as that would turn them into CO2).

rdevsrex 25 minutes ago | parent | prev | next [-]

This is the most Euro commie thing I've heard in a long while.

Sure, get rid of factory farms and CAFO's, but I see nothing wrong with raising animals on family farms where they eat a nutritious diet in line with what they evolved to eat.

Grass for cows, pasture and bugs for poultry, silvopasture for pigs. Anyone who wants to go vegan for ethical or environmental reasons is fine, but I hate this idea that all of us have to fall in line with your crazy ideas.

alpineman 20 minutes ago | parent | prev [-]

The problem is, you have to choose. Do you really think people can continue to eat meat 2-3 times a day, purely supplied by family farms where animals are able to roam free?

The reality is that the only way to feed people's insatiable demand for meat is to use factory farms. You can't factory farm without causing suffering to animals, and you can't factory farm without use of antibiotics, etc.

Also you say, 'evolved to eat'. Do you really think people were eating meat every day throughout human history? This started after WWII with mass agriculture and factory farming. That's why so many cultures have beans and rice as their primary dish: it's a perfectly balanced protein.

If 'evolved to eat' is your primary concern then actually you should be eating meat like once or twice a month, max. Evolution doesn't happen in less than a century.

How many miles does the burger drive my car? Not to question your numbers but they lack context. Also, it would be good for nature if there were fewer or no humans on this planet. But then there would be no human here to enjoy nature.

Burgers don't drive cars.

People drive cars, and people eat burgers. Is that the context you were looking for?

We've identified two ways to reduce carbon production. 1) reduce production per human. 2) reduce humans.

Only the first one is being argued for here. Conflating it with the second is just a confusion.

Meat, and red meat, is truly a miracle food. Dense in nutrients, satiating and of course tasty.

Nature needs animals as well. In fact it is essential.

Agricultural reform or innovation is certainly an avenue to explore; but this strange obsession with "stop eating red meat" is a bit too much.

But you just read an argument, and then completely ignored it, instead started brining up other aspects of red meat.

That most red meat is very co2 expensive compared to getting the proteins from other sources is a relevant argument for many of us, and not a particularly 'strange obsession' for those of us caring about reducing our co2 footprint.

In the spring I will get 3 cows with calf-a-foot who will graze the immense amount of herbal leys we have, as well as maintain our SSSI fields, and then in a few years some of them, the meanest, will go off to the abatoir to become the very finest and well fed beef that money can buy.

We'll expand the herd, and do mob grazing to maintain our species rich grasslands and our SSSI fields, while also providing the best beef to those that appreciate it, family first of course.

Grass fed and pasture fed, are not good enough. The cattle need a wide variety of food, which starts with more than grass or a monoculture pasture.
