An invasive species is an exotic species whose introduction into an ecosystem in which the species is not native causes or is likely to cause environmental or economic harm or harm to human health. It is important to note that when we talk about a species being invasive, we are talking about ecosystem or environmental boundaries, not political ones.
The indirect threats of invasive species: 1  Changing food webs: Invasive species can change the food web in an ecosystem by destroying or replacing native food sources. 2  The invasive species may provide little to no food value for wildlife.uman health and economies are also at risk from invasive species. The impacts of invasive species on our natural ecosystems and economy cost billions of dollars each year. Many of our commercial, agricultural, and recreational activities depend on healthy native ecosystems.
