The "northern pike minnow" was a by product or mistake of a decision to build damns. But this example is no mistake.. A bunch of green tree hugging types decided we needed to "re-introduce" the grey wolf in Idaho. Millions of dollars were spent to import them. They repopulated like bunny rabbits and they are now finding that they are having to spend money to kill them again. They are finding out what our great, great grandpas knew all along... wolves suck.
