How do invasive species impact biodiversity?
Invasive species tend to wipe out biodiversity. For example, feral pigs in Hawaii have taken over a lot of the areas where many different species of native lizards, small animals, and birds once lived. Not only have many of these small animals been wiped out, but the pigs are also destroyed a lot of the fragile vegetation. This is pretty typical. Kudu is a plant but it is another invasive species, this one found in North America. You can look it up on Google to see where all it’s showing up now and what all it has caused to either disappear or become endangered. So it goes. Australia has probably suffered the most from invasive species. The marsupials there were less able to compete when European settlers brought in placental mammals like rabbits and foxes and dogs and so on and these ran rampant, so a great many indigenous species have gone extinct.
