When we think about invasive species, what usually comes to mind are organisms like parasites that terrorize a natural habitat by hording resources, pushing naturally-occurring species, and at times, preying on the local species. But little do we know that there are some species, which we might often see, that are not native to where they are now.
In “Human Footprint” on PBS, Biologist Shane Campbell-Staton gets up-close and personal with invasive species you may not have realized were invaders at all. Could your favorite plant or animal be on the list? You might be surprised.
