What is the impact of invasive species? Show more Show less
Back to question

Invasive plant and animal species live in virtually all areas of the globe. The reason for their unnatural presence is because humans have accidentally or deliberately introduced them to new ecosystems. Because they have been introduced to new habitats they are not initially meant to be in, invasive species have negatively impacted their new homes. How extensive is their damage and are all invasive species harmful?

Invasive species have a negative reputation for good reason. They have ruined ecosystems by eating native plants and animals. Because of their negative effects, invasive species should be relocated or eradicated.

Invasive species kill native plant species

Invasive plants can be very aggressive. Because of their aggressive growth rates and appetite, they choke out and overgrow native plant species. Without the native plant species, the plant’s environment would fail.

The Argument

Invasive plants kill native plant species. A common vine called the Kudzu vine grows about 30 cm a day, choking out any plants that it grows over.[1] Without native plants, the organisms that rely on them will starve, harming the ecosystem.

Counter arguments

Some invasive plant species benefit an ecosystem. In California, California butterflies lay eggs on an invasive eucalyptus tree because of the deforestation of native trees.[2] Some invasive species are useful and help animals to thrive among depleting habitats.


[P1] Invasive plants kill native plants. [P2] If native plants die, the ecosystem starts to die.

Rejecting the premises

[Rejecting P1] Not all invasive plants kill native plants.
