Invasive Species Are Invades

I think that invasive species are invaders. An invasive species are living organisms that are non-native species in particular environment. In other words, it is an imported species that has a tendency to spread and is capable of damaging the environment, the human economy and human health. Some of these invasive creatures have caused the extinction of whole species and have caused irreparable damage to the surrounding ecosystem. For example, alien insects, organisms, plants cause damage to crops and forests. Some invasive fishes contributed to the disappearance of a lot of fish species through predation and competition for food. Migratory crab, during his mass migration contributes to the temporary disappearance of endemic invertebrates.
