I don't think it's clear why the root of a plant like a carrot should have any special significance except to us. What about onions, turnips, potatoes, etc?
I meant a carrot is something that would probably be more individualized than say a strawberry. So I get your point about eating from plants that grow back, but I guess a carrot wouldn’t fall under that categorization.
Also, what about animals that regrow limbs? Would you eat the arms of a starfish every so often?
I think it's possible combined with ethical farming practices I could be convinced it's not so bad to eat starfish arms (although they don't sound very appetizing).
To be clear I do already eat meat today. I am just not convinced about its necessity and am interested in ways to avoid doing it.
That said, there are some who do think the roots are significant: https://en.wikipedia.org/wiki/Jain_vegetarianism
