Re: the bison (only idiots call them buffalo), they were the motivation for the creating of the American conservation model, which is the best and most successful in the world. We have brought a number of species back from the brink, and now successfully manage hunting seasons for them. Our model is unparalleled, unprecedented, and undeniably successful. Others replicate it to their benefit, or deny it to their demise, for it is not rooted in feelings but rather science.
I'm not surprised you feel the way you do though, weren't you the one that wanted to liberate a non native species of fish into a local waterway, as an experiment?
