First: Everyone already knows that there’s no way to consume anything without causing harm to something else. It’s why the definition of veganism includes the phrase “as much as possible” not “entirely”
Second: even if we considered a plant’s life as equally valuable as a pig/chicken/cow’s— eating a vegan diet STILL causes less suffering. When you stop eating animals, you can stop murdering all the plants needed to feed those animals.
So the argument of “what if plants suffer?!?” Is bullshit, and already solved by veganism.
The other user’s thought experiment about lab grown meat is more interesting, but it’s not reality yet, and you’d need to understand the specific process for growing said meat to accurately estimate the potential avenues of suffering.
