    Toxic Deep-Ocean Water Triggered "Great Dying" ​

    "....The finger of blame for the greatest mass die-off in Earth history points to a slow, drawn-out demise that came from below, a new study shows.

    Researchers discovered that bryozoans—a common type of colonial marine creature also known as "moss animals"—began slowly declining in oceans across the world many millions of years before the mass-extinction event at the end of the Permian period about 251 million years ago..."


    "...This so-called Great Dying event wiped out about 90 percent of marine species and 70 percent of land species..."


    "...The first to go were the deeper-dwelling animals, followed by the shallow-water inhabitants..."

    :eek:​





    "...The most likely culprit for the gradual bryozoan die-offs was the upwelling of toxic water unleashed from the deep ocean by rising global temperatures..."

    Well...

    If we aren't killed by flood the chemicals from the ocean will do the trick... What a comforting thought ... :-/
