An invasive species is a non-native species that has a negative impact of the environment. They can be both plants and animals. These introduced species thrive in their new areas since they lack their natural predators and don’t have to compete against organisms that limited their growth in their native environment.
These organisms can be purposely released in the new environment or by accident. Often, these organisms are released into an area to stop a problem, but actually cause even more problems.
These species can out compete the native species for resources, introduce new diseases, and prey on the native species.
