| | Alien Invasion (Site not responding. Last check: 2007-08-09) |
 | | The spread of non-native species around the globe, due primarily to modern modes of travel and commerce, is having a devastating impact on vulnerable native species in many areas, unsettling the balance that existed prior to the introduction of the non-native organisms. |
 | | The spread of alien species has become a major cause of concern for wildlife biologists, conservation agencies, and medical professionals around the world. |
 | | From the outbreak of new diseases, such as the recent introduction of West Nile Fever to the eastern United States, to the devastating commercial losses caused by invasive exotics, such as the zebra mussel in the US midwest, the damage caused by uncontained alien organisms is substantial and far-reaching. |
