Extinction

A recent post that I read today in the midst of final exam review was from the MSN website. I think what shocked me the most was that there were several animals on this list that I wasn't aware were even extinct. Before we begin with my Mother's Day special, I thought I'd share this article as its message has lingered in my head all day. The article is titled Extinct in Our Lifetime and 11 Species We've Lost Forever. 

It's hard not to feel about such things like extinction. We must protect our Earth now.  I fear that people will only understand the importance of protecting habitat after the fact.  Something to think about when we create our garden spaces...... "Charles H. Smith / U.S. Fish and Wildlife Service Golden Toad (1989) The golden toad is not the only species to disappear in the past 40 years, but it might just be the brightest. This fluorescent amphibian was found in the high-altitude ridges of Costa Rica, but thanks to pollution, global warming and fungal skin infections, the species became extinct in 1989. Read on to find out about 10 other incredible species we've lost in the last several decades. Helle V. Goldman and Jon Winther-Hansen Zanzibar Leopard (1996) One of several subspecies of leopard, the Zanzibar leopard made its home on the Zanzibar archipelago of Tanzania. It's still unclear whether this large cat is technically extinct — there are occasional unconfirmed sightings. Cause of extinction: Locals believed the leopards were kept by witches, and aggressively hunted them. The animals were seen as evil predators that must be exterminated — and even the government was in on the campaign. In the mid-'90s there was a short-lived conservation effort but it was deemed too little, too late. Paul E. Baker / U.S. Fish and Wildlife Service Po'ouli (2004) A native of Maui, Hawaii, the Po'ouli, or Black-faced Honeycreeper, was only discovered in the 1970s. The birds inhabited the southwestern slope of Haleakala volcano. But the population declined rapidly, and by 1997 there were only three known Po'ouli left. Efforts to mate the remaining birds failed and the species was formally declared extinct seven years later. Cause of extinction: Habitat loss, along with disease, predators and a decline in its food source — native tree snails — are all seen as reasons for the bird's demise. A. E. Holt-White via Wikimedia Commons Madeiran Large White (2007) The stunning Madeiran Large White butterfly was found in the valleys of the Laurisilva forests on Portugal’s Madeira Islands. The butterfly's closest relative, the Large White, is common across Europe, Africa and Asia. Cause of extinction: Loss of habitat due to construction as well as pollution from agricultural fertilizers are two major causes of the species' decline. E. Theriot / U.S. Fish and Wildlife Service Tecopa Pupfish (1982) The Tecopa pupfish, a native of the hot springs of the Mojave Desert, has the distinction of being the first animal declared extinct under the provisions of the Endangered Species Act of 1973. The pupfish's decline was precipitated when its natural habitat was encroached upon by developers. Cause of extinction: Destruction of natural habitat. Pyrenean Ibex (2000) The last Pyrenean ibex died in 2000. However, a cloned ibex, created from skin samples taken from the last Pyrenean ibex, was birthed in 2009. It died shortly after birth from lung complications. Cause of extinction: Hunting of the ibex had caused the animal's numbers to seriously dwindle and conservationists blame the Spanish government for failing to act in time to save it. West African Black Rhinoceros (2006) The majestic West African black rhino was declared extinct in 2006, after conservationists failed to find any in their last remaining habitat in Cameroon. The West African black rhino was one of four subspecies of rhinoceros. Cause of extinction: Poachers hunted the rhino for its horn, which is believed by some in Yemen and China to possess aphrodisiacal powers. Javan Tiger (1979) Similar in appearance to the Sumatran tiger, the Javan tiger was native to the Indonesian island of Java. In the 1800s they were so common they were considered pests by island natives, but as the island was developed their population dwindled. By the 1950s, only 20 tigers remained. Cause of extinction: Loss of habitat and agricultural development led to severe population decline. Conservation efforts in the 1940s and '50s were unsuccessful due to a lack of adequate land and planning. Spix's Macaw (2004) Spix's Macaw, also called the Little Blue Macaw, was known for its beautiful blue feathers. While some still exist in captivity, these tiny blue birds are extinct in the wild. Cause of extinction: Habitat destruction and illegal trapping and trade contributed to the macaw's dwindling numbers. Round Island Burrowing Boa (1975) Native to Round Island, a tiny island off the coast of Mauritius, the Round Island Burrowing Boa preferred to live on the topsoil layers of volcanic slopes. It was once found on several other islands around Mauritius, but its population had dwindled by the 1940s, and it could only be found on Round Island after 1949. It was last seen in 1975. Cause of extinction: The introduction of non-native species of rabbits and goats to the island destroyed vegetation and upset the boa’s habitat. Dutch Alcon Blue Butterfly (1979) This Dutch butterfly — a subspecies of the Alcon Blue — was found mainly in the grasslands of The Netherlands. While closely related species (pictured here) still exist in parts of Europe and Asia, the last Dutch Alcon Blue was seen in the wild in 1979. Cause of extinction: Increases in farming and building had a negative impact on the Alcon Blue's habitat and caused it to lose its main food source."
