Saying killing plants is morally equivalent to killing animals is not only dumb, it’s also an argument for veganism. It takes more plants to sustain an omnivore diet than a vegan one. All the animals you eat had to eat as well, and it’s not an efficient transfer of calories. Look up trophic levels if you’re actually arguing in good faith.
So I agree! Killing plants is murder! So you should go vegan and stop killing excessive plants for your selfish taste buds.
