Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Saving the climate is not going to be done by guilting consumers into changing individual consumption habits. Enough with the green consumerist bullshit that only serve as neoliberal justifications for inaction.

If the meat industry is hurting the planet, REGULATE IT.

[–] usernamesAreTricky@lemmy.ml 34 points 10 months ago* (last edited 10 months ago) (7 children)

The problem is not that the method that meat is produced, it is that it is produced at high levels at all. The inefficiencies don't go away by changing regulations. We are going to have to have changes in production and thus consumption levels. It's going to be difficult politically to get any policy like that through if people are unwilling to reduce any on there own as well

Do I think systematic actions are needed, yes, but if we're going to get there we'll have to start with some degree of individual action before any of it is paltable to the larger society

In order for regulations to stick, they should come from the people. If you try to regulate meat consumption without convincing people that it's good, it will just not stick. It needs to be a consolidated effort, and guilting regular people into better choices is a big part of it

Right because capitalism is bad we should all feel free to never care about our choices

[–] maegul@lemmy.ml 11 points 10 months ago

You've got some downvotes ... and there's a pretty strong "don't be obnoxious to people if you want to persuade them to do something" attitude here ... which I generally agree with.

Just to provide my own sentiment here ... at a broad, like "historical" level ... it does bother me that it seems like we've kinda become this coddled culture. Yes, we can be obnoxious about how our choices are better than someone else's bad choices.

But having frank discussions about what choices and actions are good and bad without getting stuck into ego shit fights is not only healthy but I'd argue pretty fundamental. And that includes whether it makes sense for an issue to be elevated to the government/regulatory level ... and then ... how we as the electorate are going effect that (because in the end, leadership from government these days isn't really a thing ... which is also part of the this coddled "make every feel good about themselves" culture I feel).

I recently started calling this something like "secondary climate denial" (which I got from somewhere I can't remember). The idea being that a fair amount of people (myself included I'd say) have acquired a sort of learnt helplessness and passiveness about the climate crisis ... have learnt to deny the possibility of there being things that they can actually do and that are actually worth doing. Sometimes we expect things to be more effective and more quickly than is reasonable, so we do nothing. Sometimes we think the world is too big and powerful for us to move it, so we give up.

Sometimes we get worried about letting perfect be the enemy of good and so we give up. And what have we all got to show for it ... what have we actually done?!

If/when it goes to shit and we're sitting grand-children who are asking us why we didn't stop it from happening and what we actually did ... are we really going to be satisfied that, well, we had some arguments online about it and tried to eat vegan as much as possible? Won't the grand-children then say "I'm vegan too, but what did you do to stop it? Didn't you do anything?"

Vegans love to conflate all meat into one big group because their goal is to make veganism look good in comparison.

In reality, beef is the main problem.

graph

It would be a lot more environmentally effective to convince people to reduce beef consumption and replace it with chicken/pork instead, but vegans aren't interested in that because for them it's not really about the climate - it's about reducing animal suffering and death.

This duplicity muddies the waters and makes getting real actual change that would benefit the climate harder to achieve and less likely to happen.

[–] usernamesAreTricky@lemmy.ml 31 points 10 months ago* (last edited 10 months ago) (2 children)

I would hazard saying "environmentally effective" here unless we are willing to ignore some of the other large environmental issues with meat production outside of just green house gases emission. Plant-based foods are lower not just on GHG emissions, but water usage, land usage, eutrophication, fertilizer usage^1^, etc.

There's all kinds of other pollutants such as Nitrogen runoff. The rise of the pig farming is has helped fueled a crisis in Nitrogen runoff in the Netherlands for instance

There's the high level of antibiotic usage to maintaining the high levels of production fueling antibiotic resistance.

And so on.

If we do want to look at the suffering, we should also note that chicken farming does not just keep things the same, but actually makes it worse with more chickens required than other creatures due to their smaller size.

^1^ Even less synthetic fertilizer even compared to the maximal usage of manure per https://www.sciencedirect.com/science/article/abs/pii/S0921344922006528

EDIT: I should also mention that land use change (deforestation) factor can change as you rapidly increase these industries size. Deforestation makes up a large portion of beef's current emissions. Plant-based foods require overall less cropland due to not needing to grow any feed and removing that energy loss. This is not the case for chicken production. Currently beef does make up the majority of Amazonian deforestation, however, the second largest portion is growing animal feed primary for chickens. Switch from beef to chickens and you might risk just moving around where the deforestation comes from

[–] rimu@piefed.social 17 points 10 months ago (2 children)

Yes. Sloppy choice of words on my part but this is a climate change topic, here.

Chicken meat uses 4x less water than beef. I'm not disputing your point, just firming up the perspective for anyone lurking.

chicken vs beef

Clearly, vegetables are way way better. But in terms of what kind of behavior change people are willing to consider, cutting out beef is a way way easier sell than cutting out all meat.

[–] itsprobablyfine@sh.itjust.works 10 points 10 months ago (3 children)

I tell people to try going without beef temporarily. What often happens is in doing so they learn to cook a bit and cut it out (maybe not fully but mostly) long term. Then they go after pork, chicken, etc. You're right that beef is the worst offender, but we want to be careful not to overemphasise and make it seem like its the only offender. I think a lot of it is setting a tone. I'm veg not vegan but pick vegan options when available. I think the more we can normalise 'eat less meat' the better as that's pretty hard to argue with

one aspect of this is that many vegans care about the environment and the victims of animal agriculture. Things are so bad for the animals (we kill trillions per year. That's insane.) that people are desperate to do or say anything to get people to stop supporting it.

It would be a lot more environmentally effective to convince people to reduce beef consumption and replace it with chicken/pork instead,

Let’s not drive a wedge between the eco-vegans and the animal welfare vegans. Beef is the worst for climate while chickens get the least ethical treatment.

This duplicity muddies the waters and makes getting real actual change that would benefit the climate harder to achieve and less likely to happen.

Dividing an already tiny population of much needed activists is not how you get progressive change. Non-beef meats still shadow plant-based food in terms of their climate harm.

Your pic was too big for me to download but if it’s the same data I’ve seen, then beef is the worst and lamb is 2nd at about ½ the emissions of beef, and all the meats are substantially more harmful than plant based options.

The majority of corn beans and a lot of grain all go to feeding livestock. You could be a lot more efficient growing the food directly.

Corn

[–] Jaytreeman@kbin.social 14 points 10 months ago

Corn isn't very sweet (read energy rich). It's ridiculous to farm it for fuel. There are crops that are good, but they don't grow well in the continental US.

ITT people do all sorts of gymnastics instead of saying "I know but I just don't care enough"

Just be honest with yourself, if the emissions, pollution, land useage, and staggering cruelty don't bother you more than the 15 minutes of pleasure you get from a Burger pleases you just say it.

If it does, and you feel the need to defend yourself because of it just change. I promise you it's less difficult than you think and there are millions of people waiting to help you learn new delicious and nutritious methods of preparing food. Remember basically all vegans were raised carnist and most of us are complete garbage fires (as the internet so loves to point out (-; ) I promise you that you can do it and you won't even really miss meat after a few months.

[–] Noedel@lemmy.world 22 points 10 months ago

Reminder that good is not the enemy of perfect. It is much easier to convince 100 people to eat 10% less meat than to convince 10 people to become vegetarian.

I've started eating vegetarian several days a week and all it's done is introduce me to some amazing tasting food that I haven't tried before because of the dumb stigma that vegetarian means not tasty. I find that I enjoy some of these vegetarian dishes more than it's meat counterpart because it's not ruined by tough overcooked tasteless meat.

Same, meat is just something you don't need in life. The satisfaction I get from a nice delicious meal is no different than it was before I was vegan just now it is better for the environment, my health and animal welfare.

The great thing about meat and dairy consumption is that it is linear; if you eat 50% less you cause 50% less pain. Instead of trying to go full vegan, go half-vegetarian first. The next step can be taken later.

The biggest polluters are

  1. Transport 28%
  2. Electricity 25%
  3. Industry 23%
  4. Commercial & residential 13%
  5. Agriculture 10%

Agriculture (fertiliser, wild rodents, diesel, animals, rotting plants, not including plants wasted by consumers) is only 10%

We're making the best inroads into electricity. It is clearly possible and economical to convert all electrical grids to carbon neutral technology

We're starting to convert residential and commercial to entirely electric (except for the carbon and methane emissions from humans and pets, especially ones that eat beans) so that 13% is solvable

So at the moment 38% of greenhouse gases are easy, just needing political will

Another 23% is harder, industry needs some inventions, especially a green steel making process, and a green concrete making process. Both are years away and probably possible

Transport is hard. 6% is personal transport. That's easy to electrify. Trucking is harder, planes are harder still. I don't know how feasible wind power is for shipping, at least the trade winds blow the right way for Asia to America

The best bet for transport was a green liquid fuel, but the company trying to grow diesel from bacteria folded several years ago.

We are never going to decarbonise agriculture by abandoning any part of it. We can do a bit by practicing permaculture - that keeps more carbon in the ground; we can clean up animal agriculture by not feeding cattle human food, let them eat grass, and there is promising technology for reducing their (and other ruminants') methane emissions by feeding them seaweed

If we waved a wand and removed all farm animals from the world it wouldn't make a dent in carbon emissions or methane, cows would be replaced by deer which also make methane in exactly the same way cows do, but with no one feeding them seaweed

Uneaten grass would rot and be turned into methane (it's the same bacteria that work in cow and deer guts to break down grass). No one's treating rotting grass with seaweed.

Our best bet is to keep the marginal lands occupied by cattle and regulating people running cattle, requiring them to minimise their animals' emissions, or offset them

It looks like you're citing the EPA estimates for US GHG emissions by sector: https://www.epa.gov/ghgemissions/sources-greenhouse-gas-emissions

Unfortunately this is only a small part of the overall picture. For instance, it notably doesn't include carbon sinks (areas that have a net reduction of GHG) like protected wild lands. One of the biggest climate issues is deforestation, since it not only produces emissions, but also damages the earth's ability to sequester CO2. https://thehumaneleague.org/article/meat-industry-deforestation-cop26

In fact, if you look at total land use, an alarming percentage of habitable land is being used to produce meat and dairy, accounting for a relatively small percentage of protein and calorie consumption.

You also have to be careful using GHG emissions as your only metric. Animal agriculture is a major contributor to many of the environmental issues we face:

Biodiversity loss and mass extinction attributed to deforestation and use of land for agriculture.

Antibiotic resistant bacteria resulting from overuse of antibiotics to promote livestock growth.

Eutrophication and dead zones from fertilizers used to produce animal feed and runoff from farms.

Zoonotic diseases which very often originate in livestock before jumping to humans: see swine flu, avian flu, etc.

Additionally, the claim that eliminating livestock would result in a 1:1 replacement in wild mammals is patently false. Livestock is farmed intensively, whereas wild animals live in areas that are, again, carbon sinks. Just looking at the numbers, wild mammals are only a tiny fraction of mammalian biomass, with the vast majority being humans and livestock.

Considering the greater picture, the best bet is for those who are able to eliminate their consumption of animal products to do so.

The problem is only 9% of the beef production and 30% of global sheep and goat production are feed using grazing. The rest so most of them are feed using some form of human edible plants and they would not be replaced by wild animals. Furthermore it is something, which can be easily done today. We would still be able to produce enough food for every human on the planet and it would even be easier, as all the feedstock for animals would no longer be needed. So it really is a nice and easy few percent to get, which pretty much everybody can easily do themself.

For anyone unaware, deforestation is driven by animal agriculture. In fact, most of the crops grown are for animal feed. It’s inefficient, and the more efficient we make it, the crueler it is for the animals.

Eating plants will definitely do the least harm.

I get that tons of folks just don't want to stop eating meat. I'm the same. I cut out red meat because it's very much the worst offender. It was much easier than I thought to do, and I can't say I miss it or even really think about it aside from months like this.

Give it a shot. Nothing to lose except a little weight maybe.

No one is telling you what to do, but the studies are undeniable. Even if the oil industries weren't such a massive environmental disaster, that wouldn't change the wild levels of inefficiency and waste in animal agriculture. As a whole the meat industry is unsustainable, whataboutism doesnt change the facts.

We recommend four widely applicable high-impact (i.e. low emissions) actions with the potential to contribute to systemic change and substantially reduce annual personal emissions: having one fewer child (an average for developed countries of 58.6 tonnes CO2-equivalent (tCO2e) emission reductions per year), living car-free (2.4 tCO2e saved per year), avoiding airplane travel (1.6 tCO2e saved per roundtrip transatlantic flight) and eating a plant-based diet (0.8 tCO2e saved per year). These actions have much greater potential to reduce emissions than commonly promoted strategies like comprehensive recycling (four times less effective than a plant-based diet) or changing household lightbulbs (eight times less).
