Threats to Biodiversity

Risk of Extinction

Invasive species are organisms that are not native to the ecosystem who's introduction is likely to cause economic or environmental harm or harm to human health.

Inavasive species are second in causing habitat desruction. Introduced species are a greater threat to biodiversity than pollution, harvest, and disease combined.

In the United States, almost half of the species are at a high risk of extinction due to the effects of invasive species.
