New Zealand became the first country in the world to accomplish a total zoological "reset". That is, biocoenosis was returned to its original state - before the appearance of the white man.
All invasive species of plants and animals were eliminated leaving only the native. Millions of European sparrows, deer, ferrets, Australian possums and Asian rats were disposed of quickly and painlessly by affecting the genome of these species.
Again New Zealand is a country of indigenous birds, arthropods, and a plant kingdom found nowhere else in the world.
