How do ferrets help the environment?

While ferrets, like any animal, may have indirect or localized ways of contributing to ecological dynamics, there isn't enough scientific evidence supporting that they provide significant environmental benefits on a wide scale.

Ferrets are often kept as companion animals. In this context, ferrets generally don't have the opportunity or freedom to impact their natural surroundings or assist in preserving ecosystems due to the domesticated nature of their lifestyles.
