you can see soy cake, which would otherwise be industrial waste, makes up the vast majority of the soy crop that becomes animal feed
Soy cake can be used to produce textured vegetable protein (meat alternatives), tofu, tempeh, soy milk, protein powder, biofuels and bioplastics, for example.
Calling that industrial waste is just a complete joke.
The land could also be used to grow other crops for human consumption.
to be clear, the land is already being used to grow crops for human consumption.
but most people don’t want to eat it. you enumerated many of the uses it has been put to, but the fact is that we produce far more soy cake than is used in those other industries, and feeding it to animals is a good use for it.
