Pet owners have no concept of the breeding requirements required to produce their little miniatures. Thousands of dogs are/were killed in the process.
It is the same everywhere over all species and ecosystems. We do what we do to survive, if that includes breeding unsustainable breeds because they are fun to pat...
This is how nature works, There is no targeting of specific survivable mechanism oriented to environment, rather a bird shot pattern that hits everything at random.
Those who think they can control the natural interaction and horror of nature are vastly more dangerous than what we see as a tragic result of natural mayhem.
I have no problem with having the government in control of all pet ownership and whatever prohibitions whatever locals decide to enact.
I do not obey laws that are not physically enforced.
