You've probably got a list of animals you'd never think about hurting. But what if those animals were crowding out other animals you valued?

That is the ethical issue faced by the people manage the curbing or removal of invasive species.

Like the Tui Chub, a fish in Diamond Lake that has crowded out sport fish in the past, leading wildlife managers to poison the lake to kill all the fish (and later re-stock).

Joseph Tuminello studies this kind of ethical dilemma in his doctoral research in Texas. He joins us with an overview of some of the ethical questions in invasive species management.
