Invasive species eat native animals
Invasive species eat native animals. Without native species, the ecosystem they reside in will suffer.
The argument
Invasive animals eat native wildlife. For example, the Everglades in Florida has anacondas, pythons, iguanas, and wild boars that eat native animals such as crocodiles and smaller mammals. Since they are not natural predators, native animals do not stand a chance of defending themselves.
Premises
[P1]Invasive animals like the pythons and wild boars in the Florida Everglades eat native wildlife such as crocodiles and small mammals.
[P2] Because they are not natural predators there, native animals cannot defend themselves against them.
[C] Therefore, because invasive species eat native animals, invasive species harm native animals.
Counter-arguments
Invasive species can get rid of pests. The Harlequin Ladybird was introduced to Europe and North America to control aphids which killed crops. Invasive species benefit ecological systems, not harm them.
Rejecting the premises
[Rejecting P1] Not all invasive species eat native wildlife. [Rejecting P2] Native animal species can adapt to changes.
