If so, then nothing but greenhouse grown plants are vegan. Millions of rodents and rabbits are killed each year (not really an exaggeration, they reproduce prolifically) using a variety of methods to prevent them from damaging crops. One amusing example is removal of burrowing animals with FAEs; propane and oxygen is injected into a burrow and detonated. (Google for "rodent blaster" if you're curious.) It does have the advantage of being an entirely organic method of agricultural pest control.
