Better than being headed into a new medieval era because climate change caused civilization to collapse.

There is no universe where climate change causes the literal collapse of civilization. Exaggerating the risks of something just destroys the credibility of the people doing the exaggerating: consider DARE and drugs.

A large asteroid impact would do it.

this is a half-baked ‘solution‘ that just makes eating meat a luxury. a thing only for the rich. it’ll be like crimes that are punished by a fine - they just become the ‘fee’ that allows the propertied class to do whatever they want. beef is deadly for humanity because of destructive water and land usage (Vice had a great video showing the Amazon deforestation due to beef production). edit: my point is that the prope…

If only allowing the rich to eat beef will help save the planet then I'm for it.

If only eating the rich will help save the planet then I'm in.

> When you grow plants, you take carbon out of the atmosphere. When you eat it, you release it back into the atmosphere. So the electricity and diesel that are involved in growing plants come from the atmosphere? That's new to me.

They didn't say that. > In practice, farms regularly use synthetic fertilizers. They might cut down trees to clear fields for animals. They use heavy, oil burning equipment. These, and many other practices, actually increase atmospheric carbon, and for that reason should be discouraged. I cannot say anything wherever cows really are inconsequential wrt the warming effect, but it definitely goes against what's general…

I suppose you could grasp at that straw, but the reality is that grain farms always use diesel and electricity, not just "heavy, oil burning equipment", no matter how much you might think they don't, and that's multiplied by a factor of 10 when you feed that grain to a cow.

As someone in the Gen X demographic who has never smoked, I've watched the anti-smoking campaigns and shift in attitudes towards smoking with interest - particularly how resistant smokers were to initially giving up smoking. I feel like eating meat is going to be my generations equivalent of smoking. Intellectually, I agree that eating meat is bad for the environment, cruel to animals (esp industrial farming) etc ...…

Did you notice what drove the change in attitudes towards smoking?

Well, in my country (where tax in cigarettes etc was already very high; no one cared) it was not being allowed to smoke almost anywhere anymore, then, when that became normal (many people did it anyway for a few years until the fines got too high), people who used to smoke and everyone else found it smelly and then, way way way way behind that somewhere, something with health.

Revealed preferences don't match that rhetoric. - People are not migrating North in droves. They are not preparing in any way. - Nuclear energy, the only realistic solution to climate change, is not being supported. It's actually being retired early in many cases and replaced with coal of all things. - Property prices on the coastline are going up. President Obama, who has access to the best information and experts,…

> People are not migrating North in droves Yes, because - you might be surprised to hear - people actually like to life where they are born and raised and require catastrophic hardship (such as the Syrian civil war) to actually start a migration.

Hm, this seems to be missing the point that plant monocrops destroy the soil and are not nearly as efficient a source of food for the human body as fresh animal meat. Regenerative agriculture, which ideally requires both animal and plant cultivation, would be a better path forward if it could scale. If I remember correctly the papers that originally thought cattle were a big contributor to global warming turned out t…

Yesterday in the investigative journalism program Zembla on Dutch TV they addressed how the entire agri sector was beholden in a vicious cycle of greed. Where in the supply chain from Monsanto to supermarkets huge profit margins were raked in. Large part of the blame is at the supermarkets. While farmers are left no choice but to apply extractive methods (furtilizers, pesticides) to farm their lands to keep their heads afloat. Even with their huge farms and professional production methods they are effectively exploited.

In this story the supermarkets say "We'll give consumers the choice", but for them that means choosing eco products that have ~40% higher price and they don't do that (~5% of sales is eco-friendly), so this doesn't work.

Once again it is politicians who need to take some tough measures, but they find powerful lobbies in their path plus they do not dare to take impopular measures that make products more expensive, for fear of losing votes. So for 50 years things got worse and worse.

One solution mentioned was what social enterprise True Price [0] is trying to establish: explicitly pricing the detrimental externalities that until now are shoved as costs to future generations. A pack of regular coffee with externalities priced in would go from, say, $5 to become $10, while a pack of eco-friendly coffee would go to $6.50. The surplus to the price should be reserved in a fund with which farmers can make the transition to sustainable agriculture.

> The simplest way to cut beef output is for people to eat other animals instead, or become vegetarians. That’s like, in 1900, saying “the simplest way to prevent road deaths is for everyone to drive slower.” That’s not simple at all - that’s an intractable group behavior problem. What you really need is for the government to come along and put up speed limits. Most people will push those rules, a few will flout them…

The ironic thing is that speed limits reduce revenues collected from gas tax via better fuel efficiency from driving slower.

This implies that the land used to grow cow feed couldn't be used to instead grow human-consumable crops or left fallow as a carbon sink. I'm not aware of any studies showing that.

You make a strong argument. I think this is a case where we'll find the global optimum somewhere in the middle. Deforesting the amazon to grow corn for cows is something I'm sure we can all agree is bad. Should we use livestock to eat cover crops and waste products like corn husks and cobs? This way we reuse waste and produce high quality protein to supplement our diets. Should we graze cattle on natural grasslands l…

I'm pretty sure that feedlot studies say that the usual situation in the US is that 1/2 of beef calories come from a 10:1 ratio of human edible calories.

So sure, go for 100%-grass-and-not-human-edible-food-fed beef, but that's not the current system.

There is a certain amount of carbon in the atmosphere, and a certain amount of carbon in the ground. When you burn oil, you take carbon from the ground and introduce it into the atmosphere. This increases the total amount of carbon resident in the atmosphere. When you grow plants, you take carbon out of the atmosphere. When you eat it, you release it back into the atmosphere. The total amount of carbon resident in th…

I've always thought along the same lines. But whatabout methane being 10 times the pollutant?

It's a concern, but fortunately if cattle population stays constant, their portion of the atmospheric resident methane will also remain constant, because methane degradation will keep pace with emissions.

Compare this to cars. Even if the number of cars remains constant, their contribution to the C02 pool grows every day.

So we should avoid increasing cattle population 100x, but we wouldn't want to do that anyway because we'd have nowhere to put them, and I certainly wouldn't support deforestation.

If we start banning certain foods like beef. We should do it equally. Only allow those crops with lowest CO2 per calorie/nutrient output. As clearly taste is secondary.

After all, replacing all we eat with tasteless gruel and water is acceptable by this logic.
