There are more than 120,000 species of butterflies in the world. There are more than 10,000 species of butterflies in North America. Out of these butterflies species in North America there are 17 different species which are threatened by extinction. No known species has officially become extinct in the North American region.
Threatened means that the animal is vulnerable to extinction and the population of the animal is declining. (ex: Certain species of whale population are being threatened.) Endangered means that the animal will soon be extinct if nothing is done about it. Some endangered animals are being bred in captivity until their numbers increase enough to be released back in the wild. (ex: Bald Eagles are an endangered species of bird. Pandas are an endangered species of bear.) Extinct means that the animal has completely died out and there aren't any left of this species. (ex: Dinosaurs are an extinct species of reptile. Dodo is an extinct bird.) Here's a visual: Threatened-------------> Endangered---------------> Extinct
The fisher, Martes pennanti, is a member of the weasel family and a close relative of the pine marten. Populations declined as a result of trapping for their furs and habitat loss. Fishers are relatively rare.
Mass extinction.
Currently there are only two species/breeds of lions that are alive. They are the African Lion and the Asiatic Lion. Other species of Lions like the European Lion, the American Cave Lion and the Barbary Lion were all hunted to extinction centuries ago.
Unique is the Curacao deer, Bina (currently threatened with extinction), 16 species of lizards, 168 different birds and many tropical fish.

Biologists have now listed all those plants and animals that they know are at risk of extinction in Australia. These are called threatened species. The list includes 19 species of fish, 16 frogs, 16 reptiles, 47 birds, 39 mammals and 612 plants. In addition, there are many more species that are listed as vulnerable and some that are classified as rare.That adds up to 749 Threatened species in Australia.
If we don't conserve an animal the species number will drastically decrease and resulting in extinction of that particular species. If one species become extinct it could trigger off a chain reaction and many species will be threatened.
Polar bears are not the most endangered animal ,but they are an endangered species.
Climate change currently affects at least 10,967 species on the IUCN Red List of Threatened Species™, increasing the likelihood of their extinction. The Bramble Cay melomys (Melomys rubicola) is the first mammal reported to have gone extinct as a direct result of climate change
many river dolpinhs face extinction(in Asia one species was declared extinct) and so do many other species
