Plants.
PLANTS.
What do you eat off them?
Their leaves? Their stem?
Sometimes, but you also eat their fruit.
The fruit is meant to reproduce the plant's species, and thus you are killing effectively 5-10 baby plants if you eat fruit alot. They don't feel pain, but you are eating their offspring..
Lettuce and such are leaf vegetables, meaning YOU ARE KILLING THE PLANT BY REMOVING AND EATING CHLOROPHYL. And then they either have to use their few remaining leaves to grow it back, or DIE. DEAD. GONE.
Children and dogs are not meant to be completely vegitarian. The only wolves that eat fruit are in hot deserts near termites. Most canines are carnivorous. They arn't supposed to eat raw vegetables. Children eating a strict veggie diet are missing omega3 by alot, and the only reason most of them look corpses at best is because they are pumped full of suplements and pills.
Also, by removing fruit from a plant, you are removing food from herbivore animals. LOTS OF IT.
People who are vegitarian don't care about the earth, they just want an excuse to torture themselves and animals.
