It is just bad fish and game management to introduce non-native species into an ecosystem.

There are some neutral examples (huns as example), many, many examples where things went horribly wrong and no one can show any long term good examples of where an introduced species, plant or animal, has enhanced an ecosystem.

As that is a given, why play with fire if one doesn't have to.

Just because you say it is a given does NOT make it true
