No it isn't, the idea that strict vegan diets would have stoped climate change is just nonsense. Run the numbers. "Strict vegan diets" is the attitude of US activists telling the developing world that they need to change their behavior before the US activist is willing to accept driving less or adopting dense urban infill housing.

"Making money" is the incentive system of society. Technology has now aligned society's incentive systems to promote climate action.

People who refused to acknowledge the reality of human society, refused to acknowledge that the profit system exists whether they want it to or not, are responsible for focusing action on ineffective means of change.

It’s one piece of many. They never said it was the only piece. You’re straw-manning this comment.

And vegan diets would make a big dent, look up agricultural sector emissions, look up beef emissions and methane from their burps. It’s a major factor after transport and electricity.

Then explain voluntary work or all the people risking their lives for other people they don’t even know.

Human society existed before money.

And nobody said that a vegan diet would have stopped climates change, they said strict vegan diets, ground based mass transit, dense development & re-wilding, energy transition.

Just picking one and say that would help is a nasty tactic.

It’s like saying you need water, food and sleep to live and you say, nope, water alone doesn’t keep you alive.

The reality is, consuming and producing less works but it’s harder then keep going and hope for a technical solution.

Same with being overweight, more sports, less food works but doesn’t make fun.

Thank you for writing that, because I think it is the key point. It's very easy to blame "decrepit old men" because that makes it someone else's fault - and I get it, as I think that there are a bunch of decrepit old men that deserve a lot of blame.

But democratic societies (and even authoritarian ones that are still somewhat subject to mass unrest) were never going to accept large negative impacts for a consequence that was not immediate and in your face. Like you put it, just go around and ask your average Joe or Jane if they would vote for any candidate who demanded strict vegan diets (or heck, even a lot of the other things on GP's list). You're fooling yourself if you think it's only decrepit old men who don't want that stuff.

And regarding GP's comment that "And more people made money sabotaging solar+battery pricing in the US." Yes, there are some people trying to sabotage this to make money for themselves, but it will not take them too long to fail miserably precisely because the economics are not in their favor. Just look at Texas - not exactly a place known for its love of vegan diets, among other things - and solar, wind and now batteries are now a huge portion of the energy mix and growing fast precisely because it's economical.

>Livestock production accounts for 14-18 percent of global greenhouse gas emissions, including 32 percent of methane gas emissions worldwide.

14-18% seems like a fairly significant chunk, no? and what if we just started with not eating beef, all of us, especially the USA? that'd cut down the emissions by quite a large bit

I also feel like the idea that technology will save us can only exist if you're fully ignorant of the sheer amount of money poured into lobbying by various industries into deregulation (like, for eg, the beef industry: https://www.ucs.org/about/news/agribusiness-industry-lobbyin... or Taylor Farms https://www.wired.com/story/diarrhea-outbreak-taylor-farms-m...)

not to mention the abandonment by state energy companies like Georgia Power of their solar/renewable goals and full buy-in to building yet more gas turbines in order to attract hyperscale data centers. I was part of some organizing against this in my city: https://atlpresscollective.com/2025/12/18/public-service-com...

just look at the funding for renewable R&D in the past few years - the reason we have the market we do now is that huge spike (thanks, Obama) in 2009 that drove down the cost of manufacturing and drove up conversion efficiency. that much investment into the renewables sector hasn't been the same since, especially now: https://www.theinvadingsea.com/2025/11/05/fossil-fuels-oil-c...

Significant amounts of the third world are already eating de-facto vegetarian or vegan diets. Many for religious reasons (i.e. in India where the vast majority of people either eat no meat or only chicken/fish), and many others for financial reasons.

Strict vegan diets would objectively massively help reduce climate change.

who wants a "strict vegan diet" ? I see detractors who want to derail the topic using distasteful, demanding examples..

This personal belief is grounded on an assumption that all mankind follows a neoliberal or even libertarian economic model.

Back to reality, west Europe is firmly a social democracy where states impose behavior through law, regulation, and policy, which is topped by a federal system that coordinates policies. Countries such as China are totalitarian with a centrally managed economy that's guided by N-year strategic plans.

You're assuming that we keep the same system and that no sacrificing can be made. Technology is seen as the only solution because of the primary assumption that we need to keep growth and late stage capitalism. Degrowth, relocalisation, lower consumption are all solutions that would work better than technology (there are very serious people out there who demonstrated that technology won't replace the energy we need, Jancovici to name just one).

Technology is the only option in constant system, but with nothing happening, the system won't remain constant for long, and sacrifices will have to be made, not by choice.

Also while developed countries are affected , developing countries like Bangladesh, India are disproportionately affected, mostly a function of geography and a lot of history (very high population etc.). Honestly once AI becomes powerful enough most of these people will literally be leftovers with nothing left to contribute to the world with civil war precursors you see in other forms today essentially the same symptom of fight for limited resources.

The developed countries have so much land, water, resources that they will adapt although inequality within will be an issue and tbh at this point there is never any thought given to the wider world, which if one things about honestly never was.
