roboticmind··on Cardiovascular health and cancer risk associated with plant based diets
Earlier you were saying how you didn't trust only observational studies and wanted to see people actually doing randomized trials. That was for a meta-analysis, but this neither a meta-analysis nor an RCT. It is a single purely observational study.

Further, looking at their 95% confidence interval graphs... you can see the many of trends could potentially be completely reversed and still within the 95% confidence interval. Their 95% confidence interval contain probable outcomes where 140mg/dL was the worst possible level as well

Further it also still finds increased risk for heart issues with higher LDL.

> Any increase in LDL-C levels was associated with an increased risk of myocardial infarction.

roboticmind··on Cardiovascular health and cancer risk associated with plant based diets
This meta analysis talks about the findings of various RCT (Randomized controlled trial) studies in there.

From another meta analysis which talks about this more directly:

>Nevertheless, several RCTs have examined the effect of vegetarian diets on intermediate risk factors of cardiovascular diseases (Table 1). In a meta-analysis of RCTs, Wang et al. (22) found vegetarian diets to significantly lower blood concentrations of total, LDL, HDL, and non-HDL cholesterol relative to a range of omnivorous control diets. Other meta-analyses have found vegetarian diets to lower blood pressure, enhance weight loss, and improve glycemic control to greater extent than omnivorous comparison diets (23-25). Taken together, the beneficial effects of such diets on established proximal determinants of cardiovascular diseases found in RCTs, and their inverse associations with hard cardiovascular endpoints found in prospective cohort studies provide strong support for the adoption of healthful plant-based diets for cardiovascular disease prevention

India and Hong Kong have very different levels of income. Comparing the two is rather misleading when that's going to affect things like access to healthcare

roboticmind··on Cows in Texas and Kansas test positive for highly pathogenic bird flu
And then emit higher methane in the process even in areas where it could theoretically work out largely due to lower slaughter weights and longer times to raise them

>If beef consumption is not reduced and is instead satisfied by greater imports of grass-fed beef, a switch to purely grass-fed systems would likely result in higher environmental costs, including higher overall methane emissions.

roboticmind··on Cows in Texas and Kansas test positive for highly pathogenic bird flu
It's not just South America. It's even in places like the UK

>Most of the UK and Ireland’s grass-fed cows and sheep are on land that might otherwise be temperate rainforest – arable crops tend to prefer drier conditions. However, even if there were no livestock grazing in the rainforest zone – and these areas were threatened by other crops instead – livestock would still pose an indirect threat due to their huge land footprint

(and those "grass-fed" cattle are also fed crops too)

>Furthermore, most British grass-fed cows are still fed crops on top of their staple grass

roboticmind··on Over-grazing and desertification in the Syrian steppe root causes of war (2015)
I don't understand the relevance of that study here? The study is not looking at effectiveness of "holistic grazing"? There's not any environmental analysis here nor anything quantitative. It's mainly looking at interviews with people and talking about the friction in using those kinds of techniques

roboticmind··on Could seaweed be the 'fastest and least expensive' tool to fight climate change?
It doesn't do as much as you think for cattle feed as most the high % numbers you see touted are only looking at feedlot emissions - which are only 11% of overall cattle emissions. Actual reductions are pretty small

>What’s more, feeding cattle algae is really only practical where it’s least needed: on feedlots. This is where most cattle are crowded in the final months of their 1.5- to 2-year lives to rapidly put on weight before slaughter. There, algae feed additives can be churned into the cows’ grain and soy feed. But on feedlots, cattle already belch less methane—only 11 percent of their lifetime output

[...]

>Unfortunately, adding the algae to diets on the pasture, where it’s most needed, isn’t a feasible option either. Out on grazing lands, it’s difficult to get cows to eat additives because they don’t like the taste of red algae unless it’s diluted into feed. And even if we did find ways to sneak algae in somehow, there’s a good chance their gut microbes would adapt and adjust, bringing their belches’ methane right back to high levels.

[...]

> All told, if we accept the most promising claims of the algae boosters, we’re talking about an 80 percent reduction of methane among only 11 percent of all burps—roughly an 8.8 percent reduction total

roboticmind··on Could seaweed be the 'fastest and least expensive' tool to fight climate change?
>We model a nationwide transition [in the US] from grain- to grass-finishing systems using demographics of present-day beef cattle. In order to produce the same quantity of beef as the present-day system, we find that a nationwide shift to exclusively grass-fed beef would require increasing the national cattle herd from 77 to 100 million cattle, an increase of 30%. We also find that the current pastureland grass resource can support only 27% of the current beef supply (27 million cattle), an amount 30% smaller than prior estimates

[…]

>If beef consumption is not reduced and is instead satisfied by greater imports of grass-fed beef, a switch to purely grass-fed systems would likely result in higher environmental costs, including higher overall methane emissions. Thus, only reductions in beef consumption can guarantee reductions in the environmental impact of US food systems.

However the levels of suffering is magnified by animal agriculture especially because it takes a large amount of crops for feed

As for fertilizer, the usage is lower without animal agriculture even compared to best case usage of manure

> Thus, shifting from animal to plant sources of protein can substantially reduce fertilizer requirements, even with maximal use of animal manure

roboticmind··on Amazon funds seaweed farming at offshore wind farm to test CO2 capture
That's still red seaweed ("FutureFeed’s solution uses a specific type of red seaweed"). It like other seaweed additive, can only really be used in feedlots where as mentioned above, only account for ~11% of emissions
roboticmind··on Amazon funds seaweed farming at offshore wind farm to test CO2 capture
They are not looking at *overall emissions* which is the exact reason why they are getting larger numbers. They are only looking the emission reduction in feedlots which is a major point of that article I cited

It doesn't significantly reduce emissions and certainly doesn't eliminate it. The numbers often touted for it are rather misleading as they miss how little it can change overall emissions

roboticmind··on Alaska snow crab season canceled after disappearance of an estimated 1B crabs
Where are you getting that from? Other data suggests that even worst case production of plant sources of protein come out far ahead of even the best case production of meat, dairy, etc.

> plant-based foods emit fewer greenhouse gases than meat and dairy, regardless of how they are produced. > […] > Plant-based protein sources – tofu, beans, peas and nuts – have the lowest carbon footprint. This is certainly true when you compare average emissions. But it’s still true when you compare the extremes: there’s not much overlap in emissions between the worst producers of plant proteins, and the best producers of meat and dairy.

roboticmind··on GPU mining no longer profitable after Ethereum merge
Gridcoin rewarded seti@home when seti@home was operating and still rewards a number of other BOINC projects. It is proof of stake based and the rewards are layered on top.

There is a similar cryptocurrency called curecoin for folding@home although I think they do use SHA-256 mining (i.e not useful computations) for part of the rewards

roboticmind··on Ask HN: What are some of the best documentaries you've seen?
How is that relevant?

Are you saying that because cruel things happen in the wild we should be fine doing cruel things? I doubt we would accept someone justifying other acts by showing how it occurs in the wild such as stealing all the way to something extreme like cannibalism.

roboticmind··on How sustainable are fake meats?
Even best case emissions of meat production are higher than the worst case emissions of plant protein

> Many argue that this overlooks the large variation in the footprints of foods across the world. Using global averages might give us a misleading picture for some parts of the world or some producers. If I source my beef or lamb from low-impact producers, could they have a lower footprint than plant-based alternatives? The evidence suggests, no: plant-based foods emit fewer greenhouse gases than meat and dairy, regardless of how they are produced.

roboticmind··on Debate: Should children and adults avoid consuming animal to avoid disease?
An abstract is supposed to be a summary. Many people will read only an abstract since they think they are just getting a shorter version of something and stop there
roboticmind··on Debate: Should children and adults avoid consuming animal to avoid disease?
You have to read further down to know that it was someone assigned to argue this point of view - not that it was a study or review where someone looked at research and came to that conclusion. Reading the abstract and title did not give me the impression that someone was assigned to make that argument. Those are very different

roboticmind··on The richer people get, the more meat they eat
As long as the methane stays in the atmosphere it does warming. Taking 100+ year to reach equilibrium concentrations still means having massive amounts of methane in the atmosphere doing warming, just at an equilibrium.

Because it breaks faster than CO2 is why we should really reduce the emissions today because it presents us a great opportunity to save more warming effect in the future

> Nevertheless, while methane may have a short atmospheric lifetime, its effects are not ephemeral provided the source of the methane continues to exist. For as long as livestock continue to be farmed, methane continues to exert a warming effect upon the climate.

> As such the argument that since methane’s impacts are temporary, they do not matter, is wrong. Its effects will in practice be permanent, unless ruminant production is halted.

> Methane emissions also increase the risk of us ‘overshooting’ the 1.5°C/2°C target, potentially tipping us into unknown climatic territory, with possibly devastating effects on agriculture, wildlife’s ability to adapt, heat stress in humans and animals, and more
