We could do that with all food too. If you look at the subsidies, they are typically in grants/payments to farmers. When the produce is exported, we are essentially subsidizing a foreign country with our tax money.

And often killing the domestic production in that country, because they can't compete with the highly subsidized import.

That depends on the country's current level of production and tariff system.

My recent observations of HN is that many here take their own experience, and extrapolate that they are common and therefore anybody else could've also done it, and would be willing to. But there's empirical evidence that not many people want to stop eating meat. Look at how few vegetarians there are, compared to non-vegetarians. Do you really think those people don't know it's possible to live healthily as vegetaria…

I routinely encounter people who believe it is not possible to live healthily as vegetarians. I hired a developer who was a Hindu a couple of years back and half my team could not believe that he had never eaten meat, in part because he was very active and healthy.

Yeah, I can also confirm this. I live in the midwest, so I've encountered these people more than a few times. Even on HN you'll see a lot of people arguing that vegetarianism is actively unhealthy if not downright unsurvivable without supplements.

Worth noting that methane is up to 84 times as damaging as CO2 in the atmosphere upon release. ( https://www.edf.org/climate/methane-other-important-greenhou... ) That means that (ironically I guess) this has the potential to be just about the biggest bang-for-buck weapon we have against climate change in the next decade. I don't envy the researchers having to explain it to their kids later though. "What'd you do in…

"this has the potential to be just about the biggest bang-for-buck weapon we have against climate change in the next decade." Now we only need to get cars 'n' lorries etc, ships and aeroplanes to eat the stuff and it's job done. Obviously, coal and gas fired power stations are already changing their diet and farting and belching less methane already. The Great Barrier Reef is already de-bleaching and the Greenland ic…

So your problem with what I said is that there’s clearly far more to it than cow farts so you feel like we therefore shouldn’t do anything at all.

Or maybe I said “best bang-for-buck” and you heard “planes eat seaweed”.

Norman Borlaug won the Nobel Peace Prize for the green revolution and understood the misguidance of efficiency as a strategy better than anyone. As a tactic it works under the strategy of managing population, as he said in his acceptance speech: > "The green revolution has won a temporary success in man’s war against hunger and deprivation; it has given man a breathing space. If fully implemented, the revolution can…

>overshoot, which leads to collapse Imagine, in 50 or so years, a fairly substantial human colony is established on another planet, and it figures out how to become self-sustaining. This self-sustenance act is what we need to refine - not the going to Mars bit, of course - but what I am trying to say is that the pressure is on to find self-sustaining ways to feed humans (hint: grow local or gtfo) at the very high end…

First of all, 50 years is at least an order of magnitude off for realistic colonization of another planet. Secondly, there's plenty of land here on earth that is uninhabited and hostile that we could try self-sustaining colonies in first.

Hold up its the disgusting things we're feeding cattle that's contributing to their immense environmental impact? HUH. Maybe someday we'll realize that raising them in feedlots on 100% processed packaged food made from things like how they forage in nature is most of the problem as well, and if you raise them in distributed networks so they interact with their ecosystem instead of trampling it, and then not have to s…

Cows do not eat 100% packaged food if they eat any at all. In fact, 80% of what cows eat cannot be eaten by humans.[1] If you could add seaweed to drastically reduce emissions not would be a win for everyone. > They learned that most cow diets contain the following: Grass: More than 50 percent of cow feed is actually grass (farmers call it hay and silage). While people often think dairy cows are fed a high-grain diet…

Source doesn't look especially reliable coming from a US Dairy website, it mentions a survey from 2008 but doesn't provide a reference.

How is this any different from hybrid vehicles still burning FF? Yes, it makes it slightly better, but eating certain protein sources is a choice, whereas transportation infrastructure is an economically-limited choice. Animal ag still causes: - climate change - inefficient allocation of calories and fresh water - water, air, and ground pollution (lakes of poo, runoff into rivers) - pandemic and other zoonotic diseas…

Yep yep and yep. But people these days “but mah bacon!”

In Australia a significant amount (can't remember the specifics) of cattle is raised on land that is unsuitable for crop production. My own experience confirms this. I've seen many cattle farms around Queensland - some with low stocking density and no deforestation, others very poorly managed with no trees at all or full of invasive species. It's not as simple as eating meat = bad, but that's the message most people…

Wouldn't it be much better to just eat the soup or other crop directly, sa…

No. Feeding bovine meat cattle with commercial crops is uneconomical. It only happens as a small complement to the main diet or in emergencies. Nearly all of the cattle food grows on the terrain where they are created.

You can perfectly live on eating meat once or twice a week. Especially if your job isn’t that physically demanding. You reduce meat consumption to 1/7 if you do so. If most of us did that a lot of problems would be moot.

You assume that the only reason people eat meat is either sociological or physical workout. You have multiple subsets of population that may find it more difficult to quit meat than the others. For women (especially pregnant), meat is a source of Iron. For people with adhd, there is a correlation with meat eating (and we can assume causation as well, since adhd is genetic). Meat is a source of vitamins that have been…

I became a vegetarian over a decade ago and while it wasn't exactly easy, it certainly wasn't all that difficult compared to most of the other hard things I've done in my life. For instance, losing half my body weight (which occurred many years later because ice cream is vegetarian yo) was at least 2 orders of magnitude harder and maintaining that loss is a never ending battle. By comparison, getting out of bed to go to work is harder than maintaining my vegetarianism. Cutting back meat consumption to a mere 1 or 2 meals a week cannot be that difficult.

I also think all the talk of missing protein, iron, and vitamins is significantly overblown. Every blood panel I've ever had has been normal with iron on the high end and I can maintain an active lifestyle quite easily.

For sure almost all cattle are 'fattened up' at so-called "feed lots" immediately before butchering. In fact "grass fed" is one of those misleading labels that imply one thing but the true way to get what "grass fed" is implying is "grass fed and grass finished."

How much could this reduce the total environmental food print of cattle? I.e. including all the energy used to grow the crops they eat, the deforestation to make room for the crops + cattle, the waste the cows produce. Animal farming creates vast damage because of how inefficient it is and seaweed won't address how much feed cows need or that the world is eating more and more meat as countries get richer: > The energ…

72% of all deforestation in Queensland and 94% in the Great Barrier Reef catchment areas is a direct result of land clearing for beef production.
