we impose meaning on the world. even the idea that each of us is an individual instead of one unit is a construct. so while we can distinguish between different biological markers, the meaning we impart to that distinction is a construct. we can draw the lines arbitrarily (and we do). the distinction of race is no more natural or meaningful than a distinction based on country of origin.
i’m so glad you used this. you can find this graph there that shows that almost all the soy we feed to animals is the industrial waste from oil production
about 85% of all soybeans are pressed for oil for human uses. but a soybean is only about 20% oil altogether. that leaves 69% of the soybeans as industrial waste. feeding that industrial waste to animals is actually conserving resources.
so it’s not even true that the land used to make food for animals isn’t used to make food for people: it’s the same land.
