| ▲ | aziaziazi 2 days ago | parent | next [-] | | > the price of veggies would obviously go 10x What makes you think so? My naïve view is if people eat soy instead of an animal eating the soy there's less total soy needed, by a fair margin. The pasture animals are a different deal but that represent a tiny proportion of consumes nutrients around the world. Moreover, people that transition from omni to veggie diet don't eat 10x more veggies (with exceptions of course), even if grains and pulses are counted as veggies. We can't eat as much as what the livestock eat themselves. | |

If people could adjust their diets the impact would only be good (other than losing meat and dairy, which would be sad). | | |
| ▲ | Cpoll 2 days ago | parent [-] | | > Mass starvation probably. We aren't prepared for it. Give it 10 years and maybe it could be done. How do you figure? The same logistics lines that carry animal feed and then the animal can just carry the ~animal~ human feed directly to the consumer. Sure, the animals starve to death, but it's just a silly hypothetical. | | |
| ▲ | 3eb7988a1663 a day ago | parent | next [-] | | It takes 1000 calories of feed to make 100 calories of animal protein. While the type of animal feed is not what humans probably want to eat, the calories already exist today. Without livestock, there would be a huge surplus of available food. Wikipedia[0] Says that US directs 4345 million bushels of just corn to livestock feed. Which would be ~13 bushels or 330kg per American.

| ▲ | triceratops a day ago | parent | prev [-] | | It isn't as simple as "divert the trucks carrying corn and soy from feedlots to grocery stores". Humans can't just eat uncooked, unprocessed corn and soy. Most people don't know how to use them as ingredients. You'd have to retool or rebuild all the food processing plants that current deal with animal products. Ramp up oat/soy/almond milk production. And so on. | | |
| ▲ | Cpoll 15 hours ago | parent [-] | | > unprocessed corn and soy You mean edamame and sweet corn? You can grab an ear of the latter right off the field, husk it and eat it raw if you'd like. Or is there something about megafarms that prevent that? > Most people don't know how to use them as ingredients. If they get hungry they'll do what people have done since time immemorial and boil them. No-one will starve sitting on a cache of beans. For that matter, humans can eat pig feed directly (it's not as safe as human food, but you can boil it too). |

| ▲ | pjmlp 2 days ago | parent | prev | next [-] | | Hardly anything worthwhile, like paper straws, those are the kind of feel good measures, while the planet gets destroyed via wars, depletion of resources, wild construction, fires actually started by pyromanics and speculation for burned wood and construction sites, all everything else destroying Earth thanks to greed of a few in detriment of everyone else. | | |
| ▲ | RamblingCTO 2 days ago | parent [-] | | This paper straw thing is the dumbest take of them all. It's about reducing plastic waste (which is equally important) and has nothing to do with climate change. I have no clue how people can repeat it, as it has no obvious relation to each other? | | |
| ▲ | pjmlp 2 days ago | parent [-] | | Probably because both go together, and it has hardly changed anything when everything else keeps using plastic, a I feel good measure. | | |
| ▲ | RamblingCTO a day ago | parent [-] | | Again: I don't get it. Straws, bottle caps etc. are all reduced now. That's good. Step by step. Small litter is the worst imho | | |
| ▲ | pjmlp 21 hours ago | parent [-] | | Reduced where? Paper straws are such a nuisance how quickly they get wasted, that it is rather easy to find 1 euro shops selling "classical" straws. Bottle caps being tied to the bottles hardly matters, it is quite common to see people in parks or at the beach, breaking the cap from the bottle to split them as always. Then supermarkets still deliver most of the goods from several food areas in plastic containers for the most part. What is worst is lack of education from most people, that throw away their garbage all over the place, regardless if it is paper, metal, cardboard, wood,.... This is the problem that paper straws hardly solve, other than what, I feel good when those people "forget" their paper straws on the beach and camping ground all over the place? | | |
| ▲ | RamblingCTO 16 hours ago | parent [-] | | Paper straws suck, yes. But there are plenty of better alternatives. And just because it doesn't solve all issues at once, doesn't mean it's not worthwhile. > Bottle caps being tied to the bottles hardly matters, it is quite common to see people in parks or at the beach, breaking the cap from the bottle to split them as always. That's just not true and overly cynical. I also find it annoying, but the truth is that it has an impact. I'm not interested in further discussion I'm afraid. |

| ▲ | goatlover 21 hours ago | parent | prev [-] | | It would go up less and the climate would likely stabilize by the end of this century. People treat climate change like it's a binary when it's really a range. |

| ▲ | anon48293 2 days ago | parent | prev | next [-] | | - people would have nutritional deficits - methane production would only drop by a max of 32% due to farming - rice alone already emits 12% of world methane, this would increase - only 15% of co2 comes from farming. - 45% of the co2 from farming is plants. This would increase. So it wouldn’t do anything. | | |

Don't buy fake meats. > methane production would only drop by a max of 32% Only? If I cut your salary by 32% would you say it isn't much of a drop? > rice alone already emits 12% of world methane, this would increase And would be more than offset by the methane emitted by cattle. > 45% of the co2 from farming is plants. This would increase. Why? Feeding people plants takes less plants than feeding animal plants and then feeding people animals. | |
| ▲ | yesfitz 2 days ago | parent | prev | next [-] | | I was able to find sources for your methane production figures, but can you provide them for the CO2? To your point about increasing CO2 from farming plants: 40-66% of corn and 58%-77% of soy grown in the US is currently fed to animals, and we dedicate 5,000% more acres to growing feed crops than to vegetables[1]. Since between 3 and 10 calories of plants fed to an animal yields 1 calorie of animal product (depending on animal)[2], there would be room to either plant less, plant different, and/or use less emissive practices. 1: https://insideanimalag.org/feed-crop-takeaways/ 2: https://en.wikipedia.org/wiki/Feed_conversion_ratio#Conversi... | | |
| ▲ | gs17 2 days ago | parent [-] | | > and we dedicate 5,000% more acres to growing feed crops than to vegetables And it's worth considering what would replace all that land (maybe some would end up being biofuel production, but a lot might be allowed to return to nature if it's not profitable anymore), along with things like less demand for slash and burn. |
| |
| ▲ | gs17 2 days ago | parent | prev | next [-] | | > - 45% of the co2 from farming is plants. This would increase. And what percent of that is farming plants to feed animals? | | |
| ▲ | anon48293 2 days ago | parent [-] | | Since rice alone is more than 33% of farming methane, I’d wager not that high a percentage actually. The thing is, as you can see from the data, it’d reduce methane and co2, but not substantially. Bottom line is that there is too much heavy industry, too much oil, gas and coal, and too many people. The problem isn’t me eating meat. It’s 9 billion people eating anything. |

| ▲ | triceratops 2 days ago | parent [-] | | There's already massive deforestation to grow soy...to feed cows. Eating soy directly is more efficient, so there would be less deforestation. | | |
| ▲ | pvaldes 2 days ago | parent [-] | | Is tiresome explaining this again and again to people that don't want to understand. Not. This plan will never work. Is a dead end. Seriously. Anybody repeating this ideas again, should prove that they tried to read a handbook about ecology at least. Ecology is a science. This has been researched since the 70's. Because humans eat a lot of ocean products that fall into omnivore diet and would need to be replaced by soy. Because many arid places where you can have cattle are not suitable to culture soy, so if you remove cattle you are changing cattle by nothing and reducing the amount of feed produced, so we would need to compensate it killing some humans (not desirable) or increasing the pressure of agriculture over the natural areas somewhere. Because vegetables are not enough in very cold places. You really need to eat animal fat there. Lots of it. neither deserts or oceans or cold mountains or roads or cities are suitable to culture soy, the only remaining suitable places are the forests. A meadow with cattle were it was a rainforest is a tragedy, but replacing the meadow with a monoculture of soy is making the problem much, much worse. The meadow is an ecosystem at least. The soy field is a dead zone. | | |
| ▲ | triceratops 2 days ago | parent [-] | | > Is tiresome explaining this again and again to people that don't want to understand I feel the same way. > Because humans eat a lot of ocean products that fall into omnivore diet and would need to be replaced by soy. How much seafood? How much soy? > Because many arid places where you can have cattle are not suitable to culture soy What percent of all cattle is that? What if only free-range cattle-rearing in already-existing pastureland were allowed to continue, but feedlots and grain-fed cattle were phased out? > Because vegetables are not enough in very cold places. You really need to eat animal fat there. Lots of it. Sure. We're basically talking about Siberia, Greenland, northern Finland/Sweden/Norway, and northern Alaska and Canada. Not very many people. They could continue to eat animal fats and it wouldn't make much difference. > replacing the meadow with a monoculture of soy Soy isn't the only bean. There are literally dozens of types of beans. I don't think you realize: 1. How much soy and corn are grown to feed animals 2. How inefficient that is compared to feeding soy and corn to humans |
