Although New Zealand is know for having one of the most beautiful countrysides in the world, the sad reality behind it is that it plays host to many rare and endangered species. Because of its renown beauty and rich landscapes, there has been a rapid expansion in the human population there in recent years. Unfortunately, this has left many of the animals there homeless. The increase in population also lead to an increase in pollution there, which in turn aided in the endangering of many species of animals.
Another main issue that has lead to the endangering of some marine-life animals in New Zealand is the over-fishing and over-whaling of the ocean. According to Animal Port, this combined with the increase in pollution has lead to the endangering of the Sei Whale, Blue Whale, Fin Whale, Hector's Dolphin, and Erect-Chested Penguin. Their populations have dropped by as much as seventy-five percent since 1970. Making matters even worse, several of the species have sparse breeding rates normally, making it impossible for the population to increase under their present conditions.
One of the most critically endangered species in New Zealand is the Archey's Frog, according the Animal Plot. Although a great deal of effort has been expended to discover why their population is declining so drastically, the reason is still unclear. It is believed to possibly be a fungal infection, perhaps caused by the increase in pollution. Whatever the cause, it has resulted in their numbers decreasing by eighty-eight percent in the last seven years. The country has put measures into place to try and save the species, but it is not clear whether or not they will be effective.
The Animal Port also says that birds are being affected by the country's changing conditions as well. The Northern Brown Kiwi, the Great Spotted Kiwi, the Little Spotted Kiwi, and the Kakapo (or Owl Parrot) have all found their way onto the endangered species list in the recent years. The main cause of the birds' declining numbers is the introduction of human domestic pets. Dogs have become a new and fierce predator to the birds, and one which continues to increase in numbers. While some of the land that they live on has been protected by the government, greater measures will need to be made to save these animals from extinction.
