Stop the spread of invasive species! invasive species cause the loss of biodiversity, as well as the extinction of native plants, animals and fungi. Invasive species are introduced into an ecosystem by humans who either release the non-native species into the wild to live, or by riding on a ship, plane, or other form of transportation. The invasive species wreck ecosystems and will eventually cause the extinction of hundreds of native species throughout the world. It is our duty to stop the spread of invasive species. By signing this petition, you are promising to be an advocate for native species, as well as ensuring that you will not release non-native species into the wild.
