Invasive species affect biodiversity as well as habitat eco structure in the environment. The highest threat invasive species pose to biodiversity is the threat on endangered species. Nearly 50 percent of the 1,900 endangered species are endangered because of invasive species and the ways in which it can alter an ecosystem. Invasive species are currently the second leading threat to biodiversity. Invasive species alone, have a stronger negative affect on biodiversity than forest clearing, disease and pollution combined. For example, the Nile perch is a species of fish that was introduced to Lake Victoria as another resource for food. This new non-native fish quickly became a devastating predator and has eliminated over one hundred species of fish. The Nile perch was able to do this because they reproduced rapidly and they could out compete native fish for habitat and food. Invasive species are aggressive species that can control a newly introduced ecosystem by spreading quickly and taking over the…show more content…
