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 harm native animalsShow moreShow less
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 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.
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.
