Yeah but factory farming is a big chunk of climate change. Really climate change is the side effect of humanity’s 3-4 biggest inventions. Power generation, transportation, heating/cooling, and farming. Especially if you count deforestation in farming.

No one needs to ever eat meat. And humanity hasn’t eaten this much meat ever, outside of people living in extreme conditions like the Inuit.

For the majority of people for the majority of our existence, we ate meat maybe once or twice a month. We overblow “hunting” over “gathering” as sources of food. And I don’t need to speak on how it got after agriculture.

1. The video can just be about a problem in the west. The problem is heavily concentrated for both production and consumption in the US, China, Brazil, Indonesia and India. Really poor nations like those in Africa actually can’t afford to do factory farms because it requires a shit ton of antibiotics to keep a concentration of animals like that from dying or killing the farmer tending to them from disease.
2. Poverty is not an excuse for eating meat, there are plenty of dirt poor people in India who are vegetarian. Plant sources of protein, like beans and lentils, are almost always cheaper then animal protein unless the animal protein is heavily subsidized.
3. The fact that a practice makes a product cheap enough for poor people doesn’t excuse the moral implications of that practice. Slavery made it so cotton clothing was cheap enough for poor people, that doesn’t absolve the great sin that was slavery.
