I would agree with Raxis: to a degree. The guild does post quests where the hunter is required to capture a monster instead of kill it. And hunters will do these quests multiple times. By capturing these monsters (I presume they're delivered to the customer alive), they create opportunities for them to breed on the island. Thus creating a plethora of monsters in an unnatural habitat. This would be especially true if the monsters managed to escape into the island.
