The Invasive Animals Destroying the Planet

In this video, we take a closer look at some of the most destructive invasive animals that are causing irreversible damage to ecosystems around the world. From the United States to Australia and beyond, these species are not just a nuisance—they're fundamentally altering landscapes, wiping out native wildlife, and throwing ecosystems off balance. We rank them from bad to worst, revealing the severe impact each species has had on their environments.

The Silver Carp is threatening U.S. waterways, outcompeting native fish for food. In Australia, the invasive Cane Toad is poisoning predators, while feral rabbits are stripping the land of vegetation. Meanwhile, in New Zealand, rats have decimated native bird populations. In Florida’s Everglades, the Burmese Python has nearly wiped out small mammal populations, and feral pigs in the U.S. are destroying both crops and habitats. On Guam, the Brown Tree Snake has driven multiple bird species to extinction, and Australia’s feral cats are killing billions of native animals every year. Learn how these invasive species became such a global threat and the disastrous effects they are having on our planet's biodiversity.
