  • An inverted appeal to authority? Because a famous philosopher hated a new thing that ended up being good, you want to assume all new things will be good.

    It would also be an over-generalization because it isn’t considering the reasons Plato was against books and if all new technologies and changes would have any relation to those reasons.

    Maybe in the future, cows won’t produce methane and we’ll just have to worry about land use and the efficiency of raising cows for food. But historically and presently, they produce a huge amount of methane and contribute significantly to climate change.

    I also note that the methane isn’t a big problem, cattle methane is probably tiny compared to fossil methane

    This specifically is why I replied to you: you didn’t know something, made a guess, and were very wrong about it.

    and yet the methane overhead of a cow is stable, and doesn’t grow over time, its not a net contributor.

    Emissions have increased by 5.2 percent (9.5 MMT CO2 Eq.) since 1990. This increase in emissions from 1990 to 2022 generally follows the increasing trends in cattle populations.

    You really just don’t bother reading things if they go against your world view, don’t you?

    Methane (CH4) is significantly more effective than CO2 at trapping heat in the atmosphere: by a factor of 28 over a 100-year time frame based on the IPCC Fifth Assessment Report estimate (IPCC 2013). Over the last 250 years, the concentration of CH4 in the atmosphere increased by 161.9 percent (IPCC 2013; NOAA/ESRL 2024b). Within the United States, the main anthropogenic sources of CH4 include enteric fermentation from domestic livestock, natural gas systems, landfills, domestic livestock manure management, flooded land, coal mining, and petroleum systems (see Figure ES-8).

    Significant trends for the largest sources of anthropogenic CH4 emissions include the following:

    • Enteric fermentation was the largest anthropogenic source of CH4 emissions in the United States in 2022, accounting for 27.4 percent of total CH4 emissions and 3.0 percent of total gross emissions. Emissions have increased by 5.2 percent (9.5 MMT CO2 Eq.) since 1990. This increase in emissions from 1990 to 2022 generally follows the increasing trends in cattle populations.
    • Natural gas systems were the second largest anthropogenic source category of CH4 emissions in the United States in 2022, accounting for 24.6 percent of total CH4 emissions and 2.7 percent of total gross emissions. Emissions have decreased by 20.9 percent (45.7 MMT CO2 Eq.) since 1990, largely due to decreases in emissions from distribution, transmission, and storage.

    Methane from cows and other livestock is absolutely a big problem, it’s more than all the known gas leaks from fossil fuels in the United States. There are probably a lot more gas leaks we don’t know about, but that doesn’t diminish just how much methane we know livestock produces.

    it was a non-sequitur, it had nothing to do with the biocycle.

    Because your post is about pollutants, remember? Cows produce excessive amounts of methane, which is a very potent greenhouse gas.

    I don’t see this as a problem, we have a billion people with type 2 diabetes, getting them off carbs would have a huge improvement in their lives, health, and environmental impact (being sick is expensive).

    I don’t know why I bother talking to you.
