Gone, but not forgotten. Martha was the last passenger pigeon on earth. Martha died on September 1, 1914 in the Cincinnati Zoological Gardens. Passenger pigeons are now extinct. Extinct means gone from the planet Earth forever. Do you know how many animals and plants become extinct each year? It's at the alarming rate of up to 100 a day or 36,500 a year. And the rate of extinction is increasing each year. Find out about other vertebrates who have become extinct in the United States and Canada since 1492. What fraction of all species known to exist today could become extinct by 2025? Go to the World Wildlife Fund to find out. Photographs and information about 60 endangered species can be found on the Environmental Education website. Visit The World Conservation Union to find out more about threatened species. Key in Australia or any other region you want and click query for a list of endangered and threatened species. Are the number of endangered species greater in Austalia, Brazil, China, Unisted States or Russia? Have you ever seen people wearing parts of dead animals? Like alligator boots, bird feathers, and fur coats? Using wild animals for clothing or accessories over the years is one reason why some animals are in danger of becoming extinct. Many living things are in trouble because of destruction of their habitats, pollution, hunting or poaching, over specialization, replacement by other species or low reproductive rate. Visit the Poachers, Poisons, and Other Problems section of the National Wildlife Federation site to find out more. This site also has Copycat Pages and activities you can do in and out of the classroom to learn more about endangered species. A new danger threatens. Global warming may be causing changes in climate that are threatening species in Australia. Visit the Environmental Resource Information Network (ERIN) to find out more about global warming and species in Australia. Find out more about 4 endangered species, the bilby, orange bellied parrot, mountain pygmy possum and spotted tree frog in Australia at another ERIN website. What endangered species are found in your region or state? Visit Endangeredspecie.com and Environmental Education to find out. What can you do to prevent these species from becoming extinct? Visit National Wildlife Federation and Endangered Species for tips on what you and your neighbors can do. Choose a local species to find out more about. Some suggestions include the El Segundo Blue Butterfly, California Condor, or the California Gray Whale. |
