Question: When chatting with meat-eating friends regarding myself going vegan, they say vegetables have life too. How should I reply?
Answer: You can reply that plants do indeed have life, but not sentient life (with feelings, emotions, reasoning). For example, carrots do not scream and struggle when uprooted but even a chicken will do all that to her last breath because she clearly does not want to die, while craving to live, just like us.
Also, it can take up to 14 pound of crops to fatten up an animal for meat, to create 1 pound of meat. Thus, to do the least harm, if your friends truly believe plants are sentient, they should all the more eat only plants directly, like you do, to save 14 times more plants.
