Astrobiology Magazine: Earth's Sixth Mass Extinction

Burlington, Colorado - United States

With the steep decline in populations of many animal species, scientists have warned that Earth is on the brink of a mass extinction like those that have occurred just five times during the past 540 million years.

Each of these "Big Five" saw three-quarters or more of all animal species go extinct.

In results of a study published in the journal Nature, researchers report on an assessment of where mammals and other species stand today in terms of possible extinction compared with the past 540 million years.

    Earth\'s Sixth Mass Extinction
    Earth may be on the brink of a mass extinction on the scale of the five global mass extinctions that have occurred during the past 540 million years. The researchers believe that a modern global mass extinction would be the result of climate change and human activities, but they also believe it is not to late to stop it.
