00:00 Invasive species can wreak havoc on ecosystems and have a global impact.

02:25 Australia has suffered greatly from invasive species, which are alien species that cause harm to the environment by outcompeting native species or lacking natural predators.

04:34 The introduction of invasive species to islands in the Pacific Ocean, such as the Hawaiian islands, is primarily due to birds carrying seeds, debris blowing onto the islands, and occasional storms bringing non-migratory bird species, while humans have played a significant role in introducing larger animals to these remote islands.

06:40 Rats can rapidly reproduce and devastate animal populations and plant species on islands, while rabbits in Australia have multiplied to hundreds of millions and caused significant damage to farms and crops.

08:58 Invasive species in Australia include the cane toad, which has spread rapidly and out-competes native species, and feral camels that roam the interior of the country, while in Florida, invasive species such as Burmese pythons, Nile crocodiles, and lionfish have been introduced through the exotic pet trade and pose significant threats to the local ecosystems.

11:08 Invasive species, such as Asian carp in the Mississippi River and North American raccoons in Europe and Japan, have caused significant problems and attempts to control them have largely been unsuccessful.

13:17 Genetically engineering versions of invasive species that can only produce males could potentially eliminate the population by making it impossible to reproduce, but the problem of invasive species is likely to persist and many established species may be impossible to remove.
