This has been my rule of thumb for a while. It should be clear as day that 9 billion people cannot all chow on hefty ruminant mammals. We would run out of land even before it cooked the climate.
The problem with chicken farming is the cruelty.
No, its also the environmental impact. We passed 350 ppm.
The article is nonsense because it must be zero. We're already in a positive feedback loop. We have to reduce all emissions to zero to mitigate as much as possible. There is no amount of emissions that are acceptable.
Yes but that logic changes the goalposts a bit. The question of how to undo existing damage, or what we should do ethically, is not the same as the question of what is theoretically sustainable.
If you’re only eating two breasts a week, people can spring for the free range stuff
The article barely touches on fish. It suggests fish, eggs, and dairy are mostly fine, but doesn't explicitly say that.
Dairy has the same problems as beef. Remember, you also have to grow food to feed the food, so it's inherently a net loss of calories.
Has any society in human history been able to afford eating meat regularly? My great great great great grandfather’s journals talk about a lot of stew and veggies and he was wealthy enough that he founded a small city. We never ate that much meat.
Typically we don't need to eat meat when we are wealthy; we eat unsustainable meat when there is a famine because we must.
Subsidies and very, very cruel industrialization (torturous conditions).
If laws were just and corporate socialism was just, it wouldn't be possible for most people.
Yes, Inuit for example have a diet largely based on fish and meat. Steppe herders like mongols are another example of a culture with regular meat consumption.
Medieval Barcelona had a higher meat consumption than today. The article also gives other examples of high meat consumption from medieval England and Vikings.
The most important part: what went into the calculation? There are plenty of things besides food that impact environmental sustainability, is diet alone sufficient to achieve it? Or did they just throw the rest out?
Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
