You can never make animal production green. The amount of clear-cutting needed for beef as an example would blow your mind. Then you factor in the ground, air, and water pollution from these factory farms, and you’ve just fucked up into entire regions, just to sustain a food source that isn’t even needed.
That’s like saying “it’s more ethical if Nazis killed only adults, because they take up more space than kids in a gas chamber.”
The needless suffering and killing of any animal is horrifically unethical, and if we can, we should actively stop participating in it.
There are a ton of mental gymnastics used to justify the consumption of animals. Almost none apply to modern civilization.
