Invasive animal species and the first precept

[Kim OHara]

Then there's the perspective that the Precept is just a training rule and not a law, and for laypeople at least, one designed to help us remain compassionate and respectful of all living creatures, and to detach from the anger, carelessness and lack of compassion that motivate harm against living creatures.
While there's no escaping the bad kamma that results from intentionally harming a living creature, if the harm is approached with mindfulness and wisdom, and all other options have been sought, sometimes there is simply no other solution, and the effects of the kamma can hopefully be minimized.
As I heard one teacher say "sometimes you just have to decide who is going to live in the house and who isn't."

[Alīno]

Technicaly humain being is an invasive species.

Solution to deal with invasive spacies is to introduse a predator to re create harmony before it was broken.
