ADVANTAGES

Introduced species are those that people have intentionally or inadvertently moved beyond their native range. Introduced species can wreak havoc on native species and ecosystems. For example, an introduced predator can eradicate native species that lack the ability to recognize or avoid it – after being introduced to several Caribbean islands, the mongoose led to the extinction of many reptiles and ground-nesting birds. In addition, introduced species can threaten native species by competing for limited resources such as space and water -- in the eastern United States, zebra mussels have endangered or led to the extinction of many native freshwater mussels by growing on top of them and so preventing them from feeding as well as by filtering so many food particles out of the water that the natives starve.
