Isn’t that essentially all of Australia’s active military?
And on a similar note, only 24 rabbits were needed to successfully invade and colonize Australia[0]. And despite multiple plagues over hundreds of years, they’re nowhere close to the end of their rabbit war.[1]
In June 1935, 102 cane toads (Rhinella marina, formerly ICZN Bufo marinus) were imported to Gordonvale from Hawaii, with one dying in transit due to dehydration. By March 1937, some 62,000 toadlets were bred in captivity and then released in areas around Cairns, Gordonvale, and Innisfail in northern Queensland. More toads were released around Ingham, Ayr, Mackay, and Bundaberg.[6] Releases were temporarily limited because of environmental concerns, but resumed in other areas after September 1936.
Since their release, toads have rapidly multiplied. They now[when?] number over 200 million and have been known to spread diseases, thereby affecting local biodiversity.[7] Not only has the introduction of the toads has caused significant environmental detriment, but there is no evidence that they have affected the number of cane beetles which they were introduced to prey upon.
It seems modern humans are not very good at ecological balancing. Especially not in Australia. I believe the original local aboriginal people were trying to get the hang of it however before they were rudely interrupted by the colonialists.
We are also omnivorous masters of destroying terrain.
