What do invasive species do?

Answer 1

An invasive species is an animal, plant, or fungus non-native species that poses a potential risk to the environment, human economy, or human health.

A historical example would be fleas carrying the Yersinia pestis strain of the bubonic plague, which traveled from Asia into Europe along the Silk Road and Indian Ocean Trade route, where it was uncommon. Because the bubonic plague poses a serious risk to human health, it is classified as an invasive species. For instance, weeds like crabgrass are considered invasive because they are not attractive or desirable for lawns.

Simply put, they cause harm.
