Invasive species are non-native organisms introduced outside their natural habitat that can cause harm to ecosystems, and human health

They are often introduced by humans through activities like ballast water discharge, accidental release, or deliberate introductions

Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources

They can lead to the extinction of native plants and animals, destroy biodiversity, and permanently alter habitats

Released unwanted pets are another way invasive species spread

Invasive species can outcompete native species for resources (food, water, space), leading to declines in native populations

Some invasive species can transmit diseases to humans, animals, or plants
