* Predation: Ferrets are natural predators, and they can prey on native Hawaiian birds, reptiles, and small mammals. This can disrupt the delicate balance of the ecosystem and even lead to the extinction of vulnerable species.
* Competition: Ferrets can compete with native animals for food and resources, further impacting their survival.
* Disease: Ferrets can carry diseases that could be harmful to native wildlife and even humans.
* Damage to agriculture: Ferrets can cause damage to agricultural crops and livestock, impacting the economy.
Hawaii's strict quarantine laws are in place to protect its unique biodiversity and prevent the introduction of invasive species. The ban on ferrets is part of this broader effort.
Important note: There are some exceptions to this rule, such as for educational and research purposes, but these require special permits and are heavily regulated.
