Exotic species are simply those that do not belong in your particular habitat. They are harmful because when they are introduced into your habitat they compete with some native species and threaten to make it extinct. Such is happening with the European starling and many native North America birds.

Why do exotic species displace native species?
Often the exotic species has fewer natural enemies in the new environment but competes for the same food supply and other necessities as the native species it displaces. Sometimes the exotic species is more adaptable or more aggressive and so pushes out a native species. Sometimes the exotic species reproduces at a higher rate or more successfully than does the native species.

Are Matschie's tree kangaroo droppings harmful to the environment?
Not at all. As long as tree-kangaroos are in their native environment, there is nothing they contribute to the environment that is harmful. Their habitat is their niche, and when an animal is in its proper niche, there is an interdependence between the species and the environment.
Why do exotic species sometimes take over an ecosystem?

Exotic. i.e. foreign to that environment; this definition is of broader application than generalized notions of 'exotic'. Furthermore, human activity in the process is what can define the new organism as not being 'local'; otherwise the distinction would be completely arbitrary. If able to naturally mantain a population, these exotic species are said to be 'naturalized' to that environment.-
Definition of exotic species?
