Got it. I have no doubts that some of the plants and animals transported here could be devastating to our waters and shores as we know them. BUT, and it's a big BUT to me.....is their arrival here not a "natural" one? And if it is, who are we to say that things are not as they should be? It seems to me that we humans think that everything should stay in its assigned place and not wander about. Convenient thought for sure, but are we the best judge of what organism(s) are to be considered the survivors and the fittest? I'm not judging, just questioning. Where is line that determines what is native and what is not? "Native" Americans are descendants of Asians.....are they native? or an invasive species like us of other linage(s)?
