I'm not sure what your "not muh eggs!" story has anything to do with a discussion about animal ag industry and scaling meat production to global levels. For example, how much do your backyard chickens contribute to global egg consumption, and what would the egg market look like if all eggs came from chickens living like yours? That's the kind of topic going on here.

Animals converting plants to meat/protein is more efficient than humans directly eating an entirely plant based diet.

It sure isn't.

Why the food system is the next frontier in climate action

Virtually all paths to a net-zero-emissions food system rely on consumers in high-income countries shifting to a more plant-forward diet, according to a recent study.

Thank you, that was exactly the point.

Sorry, I may have read it a little literally/uncharitably. It sounded to me like you were saying any comparison is disingenuous.

it’s cool. Goals, standards, and raising the bar drive us forward.

Or we could switch to eating plants now. We already get 82% calories and 63% proteins from plants. https://ourworldindata.org/land-use If the world adopted a plant-based diet we would reduce global agricultural land use from 4 to 1 billion hectares https://ourworldindata.org/land-use-diets We could stay on our 1% of habitable earth, lower our agricultural footprint from 48% of land to 15%, use quarter of pesticides,…

That would be too late.

Are you aware about the amount the destruction we cause?

Without functioning ecosystems our civilization will perish, 100%. Some think we have 50 years, some are expecting the collapse any day now.

Corn subsidies provide animal ag with cheap feed. Cut the corn subsidies and prices for meat will better reflect the cost of producing it.

Corn subsidies also go to producing ethanol. Which is arguable a gigantic waste when compared to using it for animal feed. Roughly 40% of corn is used to produce ethanol[1] [1] https://www.scientificamerican.com/article/time-to-rethink-c...

It's orders of magnitude less destructive. We have to at least try to make an effort and not give up and "enjoy the status quo while it lasts" It's going to take work - giving up before trying isn't going to help. And telling others to give up won't either.

>It's orders of magnitude less destructive. Citation needed. I'm not sure you've ever been around industrial scale mono-cropping agriculture. The amount of pesticides, fertilizers, and herbicides is astronomical. And you are worried about a little cow poop? Which is natural and beneficial to the soil? Have you ever heard of regenerative agriculture? That is what I practice. We live in such an alarmist society one can…

Great for you that you do regenerative agriculture. You realise that the amount of money you needed to get to a point where that's an option to feed yourself is impossible to accrue for the vast, vast majority of the population? And - while not knowing your exact situation - I doubt you make a living off of this.

So it's a little off topic - regenerative agriculture is not going to feed the world. It's a little "I got mine, fuck the next guy" kind of thinking - not meant as a jab.

We're not going away from mono crops and fertilizer use anytime soon.

It's trivial to show that to feed animals, we have to grow food - monocultures actually. So not raising animals lets us grow less food - less fertilizer. We also cut down transportation of the feed, heating for the animals, running costs, and excrement production.

I am well aware that growing plants is not a clean, pure and friendly thing. But raising animals multiplies anything negative you find about growing plants.

(And about alarmism - I'm not reading headlines, I'm visiting farms, working on them and chatting with farmers, scientists and lawyers on the subject. I'm not just telling you to watch Cowspiracy or whatnot)

Scaling up the a new product to suddenly feed everyone on Earth based on its current low-volume tech seems like a pointless analysis. The only interesting thing about the article is going to be how the headline will probably compel HNers to go into the same old hobby horse rant against lab-grown meat.

It is very fair to point out that synthetic processes often have significant side effects. Biodiesel made from corn is a great example of "right intent, wrong overall effect" (though arguably the goal of biodiesel from corn was always more focused on energy independence than on any environment benefits). Back to the topic at hand, though. Purely from a climate perspective, does it actually make sense to target lab gr…

Also, could we grow feed for cows in more efficient manner maybe in areas where there are plentiful resources and other type of agriculture don't make as much sense? And could we with some process eliminate part of effective emissions like methane?

Somehow it feels weird that beef gets attacked in ways let's say vegan food as worst case doesn't. Should we brand all vegan food bad if some of it is grown with desalinated water in article circle with artificial lighting and heating during winter?

I want to eat meat from chickens and cows that had good, happy lives, eating the healthiest most natural form of their diet possible. I don't want lab grown meat, the concept is disgusting. As it is our food is too processed and industrial. Maybe we can focus on mixed farming instead https://www.earth.com/news/mixed-farming-could-increase-food...

I wonder who the market for lab-grown meat would be. I bet that 99% of vegetarians (myself included) and maybe 90% of meat eaters would never eat it. Meat eaters will insist on “real meat” and vegetarians don’t want any meat.

I think meat eaters would eat it. If it was better or at least cheaper than what we are currently buying.

My understanding is that we are not actually anywhere close to that point. And products are closer to the cheap products than anything quality. Think of pink slime...

Why does everything have to be all-or-nothing? Start by stop subsidizing meat.

Corn would like to have a talk with your meat subsidizes.

40 percent of U.S. corn is used for ethanol

36 percent of U.S. corn, plus distillers grains left over from ethanol production, is fed to cattle, pigs and chickens

Much of the rest is exported.

Only a tiny fraction of the national corn crop is directly used for food for Americans, much of that for high-fructose corn syrup.

Good luck enforcing a world-wide “plant-only” diet. I know people who would go to war just over that.

Black-and-white thinking, think in gradients! You eat meat X times a week? Try X -1 or more. Even a little bit helps tremendously. Everyone reading this who eat meat every day, try cutting down even one day, it will help.

Instead of beating your wife seven times a week, consider implementing "Beat-less Mondays" as a compassionate alternative.

Why is china being a bad actor mean we should ignore the real damage climate change is already causing? How are we supposed to stop china from building coal plants?

No, energy and transport is easy.

Changing agriculture and diets/habits is hard. Unfortunately we have to do everything, not just this or that.

The science is clear.

And CO2 / warming is not our only problem. Biodiversity is equally important problem to be solved.
