Researchers say the most imminent threat is a planned U.S. $1.6 billion mega-dam—the Batang Toru project

This event, called the “Permian-Triassic mass extinction,” represents the greatest catastrophe in the history of life on Earth

On a certain level, extinction is all about energy

Study reveals that the arrival of humans and their subsequent activities throughout the islands was likely the primary cause of the extinction of native mammal species there

The Chicxulub asteroid impact that wiped out the dinosaurs likely released far more climate-altering sulfur gas into the atmosphere than originally thought

Researchers found that although a mass extinction in the Late Triassic period wiped out the vast proportion of species, there appears to be no drastic changes to the way marine ecosystems functioned.

Those newfound insects didn't look quite the same as older museum specimens, raising doubts about the nature of their true identity, but DNA analysis has now confirmed they really are Lord Howe Island stick insects

Monash University, CU-Boulder show steep decline in megafauna shortly after 45,000 years ago

New fossils discovered by Uppsala University palaeontologists record an empty alien world from immediately after the extinction

Previously, scientists had thought that creatures living in the southernmost regions of the planet would have been in a less perilous position during the mass extinction event
