The real culprit is the uncontrolled population growth but nobody wants to talk about that. Ok, let's assume that people do indeed eat too much meat and that we halve our current consumption. Population grows until it has doubled and the meat consumption is then back to the same level as to what it is now. Eventually we can all be eating grass and rocks and there'd still be too much demand on nature crated by the exi…

Peak population growth rate was 50 years ago. -> https://ourworldindata.org/world-population-growth

What we are currently seeing in absolute numbers is a huge number of people with a lower growth rate out-reproducing a lower number with a higher growth rate in the past.

Education, available contraceptives, low child mortality (yes, low mortality as that makes having children less of a gamble and therefore you can get away with having fewer) automatically lead to lower fertility rates.

> I am unable to find any sources on subsidies to meat directly. Yeah, I searched around a bit (even outside of the US) and I'm having difficulty finding any proper data to back up or refute it. That's a pity, would have been nice to know either way. The best I found was data on subsidies given to individual farmers in my country (I'm not in the US), but unless I scrape the site and aggregate and categorise the data,…

Corn, wheat and soy are the monoculture agriculture.

Sure, I'm in favour of moving subsidies away from these too. Corn is largely used for animal feed (and also unhealthy stuff like HFCS) and the modern diet is much too overloaded on corn, wheat and soy and its making us unhealthy. Wheat or wheat derivatives are also added as a filler to many foods, which, as someone who has family members who have celiac disease, is pretty frustrating. There are plenty of non-animal products that it might make sense to encourage. As I said, I'm not against subsidising animal products, but I suggested reducing it because the UN said we should eat less meat.

Our studies have shown, that about 10% are first movers (willing to give up benefits, to become climate friendly eaters) and 80% will go with the default when it is acceptable. The last 10% would still need to be coerced actively by some kind of restriction.

10% is a lot. It's enough to swing an election. And no idea what the 80% would think. Also, I'm interested in global solutions, not ones that are effective in one country only. Globally, there are varying degrees of support for fighting climate change. Especially third world countries want growth and say it's the responsibility of developed economies to fight it because we have polluted so much historically. The goal…

How about we make it impossible for Trump or Merkel or Abe or Xi Jinping to sell their coal-powered production to any country in the world?

The question is rhetorical and is meant to show that 1) this proposal is not a “global solution”, as punishing a single country would hardly make any difference; and 2) you’re personifying a country’s exports, associating them to an administration you disagree ideologically with, to make it sound evil, and that is not rational nor productive.

Very well, but why don't these reports ever call for reducing the birthrate in countries where this is exploding [1]?

Now they are asking us to stop meat consumption, but the if number of people keeps increasing, what will they ask us to stop next instead of addressing the real problem?

Clearly the real issue is having too many people. Birth control is the proper way to tackle the problem.

I don't think people will stop consuming meat if you ask them nicely. You have to make decisions that will hurt the meat industry and make it infeasible. This would likely best be achieved through slowly dropping tax incentives, and transferring them over to alternatives so that people have something equally economical to today's meat.

There is no need to go from one extreme to the other. This is about eating "less" meat. People do not traditionally eat that much meat because meat used to be expensive and its supply limited. This is still the case in poor countries. In developed countries, people started to eat more and more meat as they got richer because we naturally like meat and because of clever marketing. We now eat too much meat, and also co…

> One solution would be measures to increase prices but that is a political minefield.

What's another solution?

People will keep slaves if it's legal.

Stopping the use of tax payer dollars to help people eat meat seems not that much of a minefield compared too?

Regulate the industries and trade, not people's behavior. It's much easier and you actually get results and people adapt to pricing by themselves. The reality is that we have a few billion people that are doing pretty well economically and they are going to be feeding themselves with whatever they can afford. Unless you can convince more than half of them to become vegans, that means demand for meat is going to go up…

I feel the whole 'what can you do to save the planet' is a big distraction & shifting the blame strategy. As long as we have arguments on how much meat we are eating, how much energy we use etc, we are not focusing on the fact that governments hardly regulate anything corporate.

It’s also worth pointing out that even if you don’t want to reduce the amount of meat you eat, changing the type of meat can have big effects. For example (and ignoring transport to the consumer), lamb produces about 35 kg CO₂ per kg of meat, beef 25kg CO₂ / kg, pork and farmed salmon 8kg CO₂ / kg and chicken 4kg CO₂ / kg.

This If you really want to have an impact while still eating meat, just stop eating beef/lamb altogether The amount of food and water needed to produce 1kg of beef meat is just insane Eat poultry or fish instead https://en.wikipedia.org/wiki/Feed_conversion_ratio >Cattle is the worst at something like 15:1. Aquaculture, specifically tilapia and catfish, is good at under 2:1

As already mentioned in another discussion, the ratio they use for farmed fish is "where the first number is the mass of harvested fish used to feed farmed fish, and the second number is the mass of the resulting farmed fish".

Which makes it much less positive than it first appears.

And if you don't want to wait for the government to require this you can already start today. Buy only locally farmed organic meat. Don't go to fast food places or restaurants that don't specifically declare that their meat is organic and local.

Trouble with organic is that those cows live longer, hence cause about 60% more Methan emissions, till they are slaughtered.

> Trouble with organic is that those cows live longer

Interesting. Do you have a source? I don't see a good reason for this off the top of my head.

What gives you the right to control what people eat?

I believe the government already has the right and power to control what people eat. People form the government, and people (ideally) choose the people to hold that power. In part I, too have the right to control what people eat through voting.

Which dystopia do you live in then a Marxist approach isn't going to work.
