Creative and high-tech ways now battle invasive species

about the video
Biologists are dealing with species that are increasingly becoming a threat to other species. And they are trying hi-tech techniques to turn the tide in the fight against invasive species. The Brown Tree snake, for instance, is killing native birds in the South Pacific Islands. Or the Asian Carp on the Illinois river are gradually destroying the native fish population. And a single lionfish can destroy 80 percent of the biodiversity of a reef in a few days. Lionfish, the popular aquarium fish, is armed with venomous spikes, is believed to have been released by hobbyists into the Atlantic ocean in the 1980s —and has no natural predators. Such invasive species are the leading cause of extinctions and to tackle this problem costs billions of dollars across the globe. (AP)
