exploitation is a fact of life. why is it unacceptable to exploit bees for their honey, but it’s fine to kill billions of yeasts to make bread?
Although yeast is technically living, it’s more similar to bacteria than animals or other living creatures. It doesn’t feel pain and isn’t a sentient being - there is absolutely no reason not to consume yeast or foods made with yeast.
Insects and other animals were not (and are still not in all cases) always considered sentient or capable of feeling pain. When it comes to other life forms, the fact is we have no idea how they experience the world. They are way too different from us. That doesn’t automatically make them less alive or less valuable.
And now we have evidence to suggest that we were wrong, thus there is a moral imperative to act based off this new information. There is no evidence that bacteria or similar organisms are capable of pain or suffering. If you want to just disregard all science and biology, that’s your prerogative I suppose.
