Nonnative (introduced or invasive) species can be a very hot topic. In the U.S., for example, feral hogs tear up land and destroy crops, exotic plants clog many water bodies, pythons cause problems in the Everglades, domestic cats kill birds and reptiles, zebra mussels alter our waterways... the list goes on. It is never a good practice to introduce any nonnative species into a new ecosystem, yet we humans seem to do so as a matter of course. We routinely spend substantial amounts of money to introduce supposedly beneficial species to the environment, such as bass into fishing waters. Many animals, such as Nutria and Red Imported Fire Ants, have been a fixture in the U.S.
