I know that conditions in factory farms are gross and cruel to animals, but I don’t understand how it isn’t sustainable from an environmental perspective. Less cruel and more natural means for raising livestock take up much more land. With all the beef eaten in the United States, could most of it easily be raised on grass pastures, or would that require an unreasonably enormous portion of land be devoted to grazing? As for chickens, I know they’re generally considered carnivores but are fed grains in most farms, which is less healthy for them. They also aren’t given much space to move around inside giant pens.

With the huge appetite for meat humanity has, and with a growing population, it seems like the means of raising livestock that are the most popular became that way because they were the most efficient. I’m not saying efficient is best for the animals or for the quality of the product, but it seems like it’s designed to use the least amount of land and produce the most output. Are these more efficient methods really worse for the environment than other means?

Adding onto the grain point, over 50% of the grain we grow in the US goes to livestock – we’re growing food to feed our food, which is pretty dang unsustainable.
The industry uses about half all water in the US yearly. The second highest source of methane, a really potent greenhouse gas, comes from cow burps and farts, which contributes heavily to and climate change. And don’t even get me started on how unsustainable their big vats of poop are ….
