Tiger's roar may soon be a memory - Tigers will soon join the group of animals (and humans?) that may soon be seen no more. But some researchers have used hidden cameras to film some of them in surprising places.
Most of the world's last remaining tigers--long decimated by overhunting, logging, and wildlife trade--are...
Past Climate Change Extremely Sudden
Wednesday, May 26, 2010
Something that happened to the dinosaurs 137 million years ago is right out of Whitley Strieber's Superstorm, and it could be about to happen again.

Extinction: Is it in OUR Future?
Tuesday, February 23, 2010
Years of scientific debate over the extinction of ancient species in North America have led to many theories. There's one thing all researchers agree on, however: A mass extinction occurred here in a geological instant. And other scientists have discovered that WE almost went extinct 1.2 million years ago. Will it happen again?
When our...

Sharks and whales aren't the only sea creatures being fished into extinction?the fish that much of the world relies on for food are going extinct as well. Part of the cause may be global warming, but most of it can be blamed on overfishing.

Whether or not the huge creature known as the Loch Ness monster is a living dinosaur, we DO know that millions of years ago, huge carnivorous reptiles resembling Nessie lived in Australia. If the current Nessie isn't real, we may soon be able to recreate her: A scientific breakthrough in DNA will make it possible for creatures that have been...
Is Extinction in OUR Future?
Friday, May 19, 2006
When we think of extinction events, we usually think about the asteroid that hit the earth and wiped out the dinosaurs. But it turns out the worst extinction since that happened 65 million years ago is going on right now?and we humans are the cause of it.

Ancient Evidence of Global Warming
Monday, May 15, 2006
Palentologists have avoided connecting the great extinctions that brought the Pleistocene to an end 15,000 years ago to climate change by claiming that they were due to a few thousand hunter-gatherers killing millions of animals, all within a span of a few hundred years. Now climate is finally being recognized as the key to the extinctions.
Extinction?Is it in Our Future?

Half of the 114 species that have become extinct, despite the federal Endangered Species Act of 1973, once lived in Hawaii.

Rare Pet Goes Home to the Wild
Sunday, December 29, 2002
A rare Spix's macaw has been returned to its home country of Brazil, in an attempt to revive the nearly-extinct species.

Extinction Can Be Good for You
Thursday, November 15, 2001
An newly-evolved species has a much better chance of surviving for a long time if it first appears right after a mass extinction. University of Cincinnati geologist Arnold Miller has found that the trend holds true no matter what was the ultimate cause of each mass extinction. New species were more widespread and fared better over the long run...
