1. Golden Toad (1989): Environmental pollution, global warming and bacterial infections have led to its extinction. Also known as the ring-eyed toad, a species of American toad, once found in a small tropical rainforest in the cloudy forest of Monteverde, Costa Rica, after 1989, the golden toad has not been found again.
2. Zanzibar leopard: The Zanzibar leopard has been demonized; the development of human agriculture and the sharp increase in population have forced the encroachment on the habitat of the Zanzibar leopard, and have also killed other animals that are the food source of the Zanzibar leopard, resulting in its extinction. In the 20th century, growing conflicts between humans and the Zanzibar leopard led humans to demonize this population and resolve to eliminate it. In the late 1990s, wildlife researchers concluded that the long-term survival prospects of the Zanzibar leopard were so slim that conservation efforts were stranded.
3. Po'ouli bird (2004): Habitat loss, accompanied by plague, the emergence of carnivores and food shortages, the decline in the number of local tree snails led to its extinction.
4. Madeira Great White Butterfly (2007): Extinction due to habitat loss caused by construction land and pollution caused by agricultural irrigation. The Great White Butterfly of Madeira is found in the Grand Canyon in the temperate rainforest of the Madeira Archipelago in Portugal, and the closest to this butterfly species is the Great White Butterfly, which is found throughout Europe, Africa and Asia. In 2007, experts declared the Madeira White Butterfly extinct.
5. Tikba medaka (1982): Destruction of its natural habitat led to its extinction. The fish were first spotted in Ticoba Hot Springs in California, and soon their numbers declined rapidly as the hot springs were converted into canals and replaced by bathing sites. The fatal blow is that hotels and parks have been built nearby to provide tourists with a more comfortable entertainment place. The tito's natural habitat has been continuously encroached upon by developers, leading to a sharp decline in the species until extinction.
6. Pyrenees goats (2000): Over-hunting has led to a sharp decline in the number of Pyrenees goats. They move very quickly between cliffs and cliffs, so they are also called "hanging sheep". The Pyrenees goat is large, about 1.2 meters long and weighs more than 60 kilograms.
7. West African Black Rhino (2006): Poachers hunt west African black rhinos in large numbers for their sharp horns, as some believe that the horns have an aphrodisiac effect that leads to their extinction.
8. Java Tiger (1979): The encroachment of human agricultural production on the java tiger's habitat has led to a sharp decrease in the number of Java tigers.
9. Spixer macaw (2004): Illegal capture and trade have led to a decrease in the number of macaws, and human settlements have encroached on their living environment.
10. Mauritian Cockroach (1975): The introduction of rabbits and goats destroyed native species and vegetation, destroying the habitat of the Mauritian crab snake and leading to its extinction.
11. Dutch Alcon Blue Butterfly (1979): The increase in agricultural and construction land has a negative impact on the habitat of the Alcon Blue Butterfly, causing it to lose its main food source and become extinct.
