Islands make up only about 3% of the earth's land area but host about 20% of all species and 50 to 60% of endangered species. The biggest threat to islands are invasive species, mainly rats, but also pigs and cats, who feed on nesting birds and native plants. New Zealand has been the innovator in clearing islands of rats because of its endangered populations of flightless birds which are vulnerable. One species of flightless parrot, known as the kakapo, has only 131 individuals left in the "wild" - they are closely guarded 24x7 on Codfish Island, their nests surrounded by rat traps and cameras vigilantly on the lookout for invaders.

"There is a parallel between what amphibian taxonomists do these days and what homicide detectives do. Both arrive at scenes of mayhem. Maybe they solve the crime, but they are powerless to undo it." A fungal plague is killing the world's amphibians. Hundreds of species are already gone. There is no vaccine and no cure. There is, however, an ark.

Agony and Ivory. "Highly emotional and completely guileless, elephants mourn their dead—and across Africa, they are grieving daily as demand from China’s 'suddenly wealthy' has driven the price of ivory to $700 a pound or more. With tens of thousands of elephants being slaughtered each year for their tusks, raising the specter of an 'extinction vortex,' Alex Shoumatoff travels from Kenya to Seattle to Guangzhou, China, to expose those who are guilty in the massacre—and recognize those who are determined to stop it."

Cats are apparently the culprits behind several avian extinctions worldwide. So, are cats bad for the environment?

William Temple Hornaday was an early--and probably a founding--member of the American conservation movement, and was also director of the National Zoological Park. He wrote a tremendously bitter and accurate report for the U.S. National Museum in 1894 on the extermination of the American bison, an absolute head-shaker, detailing the history of the bison in North America and its destruction at the hands of sportsmen, hunters, mindless dolts and many others who massacred tens of millions of the animal ("murdered" is the word Hornaday uses constantly). To put the whole issue in perspective, Hornaday issued a famous map showing the shrinkage of the North American bison herd, setting out the enormity of the issue instantly on one piece of paper, a summary of hundreds of pages of bad stories and big numbers.

Don't continue fooling yourself. The earth is growing and expanding rapidly. Despite plate tectonics' popular acceptance in the 60s, Samuel Warren Carey, the father of modern expansion tectonics, was publicly promoting his theories of an expanded earth as late as 1981. One of the theory's most prominent modern spokesmen is comics artist Neal Adams, who has created a number of informative videos about a new model of the universe that even manages to explain why the dinosaurs died out.

"Bryn the pygmy rabbit died in 2008, marking the end of her genetic line. This subpopulation lost its sagebrush habitat as the land was developed for agriculture ... In an off-exhibit room at the Oregon Zoo, the staff was quiet, even reverent, as they brought in Bryn. She was one of two Columbia Basin pygmy rabbits left, and since both were old females, this was a solemn occasion." Rare: Portraits of America’s Endangered Species

In 2000, the Spanish Pyrenean Ibex (a type of mountain goat) went extinct. In early 2009 it was brought back to life, the first time an extinct species has been "successfully" cloned. The newborn bucardo died of respiratory failure minutes after birth, setting a second extinction record.

80 percent of Americans say global warming is real and poses a threat to humanity. Which is good because if the global temperature raises by 4 degrees we're all dead. However only 44 percent would be willing to face any financial hardship in the name of a solution.

The world loves the banana - they are the world's most popular fruit and the fourth most consumed food on our planet. According to Johann Hari in the Seattle Post-Intelligencer, it appears that the variety of bananas loved the world over - the Cavendish - is headed for extinction due to Fusarium oxysporum (Panama disease).

There's a slight chance that an asteroid could impact Mars at the end of this month. Usually, collisions between heavenly bodies have vanishingly small odds (a million to one, say), but the chances on this one have been steadily improving, from 350-to-1 to 75-to-1 to 25-to-1 (link to Washington Post). Scientists say that this could be comprable to the famous Tunguska blast in Siberia a hundred years ago (not to be confused with this other Tunguska blast). [more inside]

The forest preserve of Białowieza is considered to be the last primeval forest in lowland Europe. Because of its unique position on the border of the temperate and boreal climate zones, it contains a unique mixture of trees, such as Norway Spruce and oaks. It also contains an interesting mix of fauna, including the European Bison, beaver, wolves, and the Nazi re-creation of an extinct species. [more inside]

It was the early 90s and the World Wildlife Federation was trying to save the rhino. They offered up Saiga horn as an alternative to rhino horns for use in Chinese apothecary shops, thinking that the millions-strong population of Saiga on the steppes of Central Asia would buffer the demand for rhinos. The result is one of the most devastating population crashes for a large mammal species in modern times. There is now a fear that the Saiga will become extinct in the next few years.

Earth, 2100 AD. Atmospheric CO2 has doubled to 1000 ppm. From shore to the horizon, there is but an unending purple color -- a vast, flat, oily purple. No fish break its surface, no birds. We are under a pale green sky, and it has the smell of death and poison. Paleontologist Peter Ward's new book links past mass extinctions to global warming and shows, absent major changes, "Our world is hurtling toward carbon dioxide levels not seen since 60 million years ago, right after a greenhouse extinction." Maybe it's time for a heresy: nuclear energy's green, and renewables aren't.

Death of a goddess Another first for China? The yangtze dolphin may be the first cetacean to be made extinct by man. Mentioned by Douglas Adams and Mark Cawardine in 'Last Chance to See' in 1989 when there were still sightings, the mammal may now be extinct. Two weeks into an international expedition to locate the last dolphins there have been no sightings. Fresh water porpoises seem to be incompatible with modern China's economic boom and accompanying environmental destruction. Attempts at conservation seem to be coming a bit late for this 20 million year old species.

What animals are endangered? (2006, updated from 2004) One in four mammals. One in three amphibians. Raw data and photos behind what others call the mass extinction crisis. Polar bears expected extinct in 25 years. In a little good news, Great Apes may be granted human rights in Spain (like the mountain gorilla -- all 660 that remain). In other news, without salmon, widespread bankruptcy expected in California's fishing industry. Me? I can only afford an electric sheep.

Today is the National Day To Prevent Teen Pregnancy. In the past decade, possibly no social program has been as dramatically effective as the effort to reduce teen pregnancy. Between 1990 and 2000 the U.S. teen pregnancy rate plummeted by 28 percent. This is great, except for the fact that this may be in part due to a decrease in male sperm count that will cause the human race to soon become extinct. It is also somehow related to the extinction of the taint. Previously.

"Killer in Our Midst : Methane Catastrophes in Earth's Past and Near Future" (a free net book) - During the greatest extinction pulse known to have happened in the history of life on Earth - the Permian catastrophe - 90% of then existing species perished. This astonishingly well written, authoritative, free book may be the most important thing you will ever read on the net or off of it : it explains in great detail an inevitable Methane catastrophe, if humans do not stop adding CO2 to the Earth's atmosphere, during which "not only would a considerable percentage of existing plants and animals be killed off, but a large percentage of the human population as well" (or the whole species). In the worst scenarios the atmosphere itself could become poisonous to Oxygen breathing life. Mundane laws of physics, expressed in impending Methane Hydrate release, dictate to humanity : cut CO2 release or perish. Simple.

Where did all the bananas go? Bananas are awesome. Popular Science has an article about how they are going extinct. Apparently in the early 1900's the main variety of banana died out and was replaced by what we know today. According to this article, it's happening again.
