an interesting read.

Terminal Permian Volcanism and Mass Extinctions

Dear Friends,

Below are some recent web pages and PDF files of publications
about termianl Permian volcanism and mass extinction. It looks
like this mass extinction was not caused by either an asteroid or
comet impact.

The Medea Hypothesis: Is Life on Earth Ultimately Self-Destructive?
by Peter Ward

http://press.princeton.edu/titles/8855.html

http://press.princeton.edu/titles/8855.html#TOC

“Using the latest discoveries from the geological record, he
argues that life might be its own worst enemy.”

“According to the Medea hypothesis, it does. Ward demonstrates
that all but one of the mass extinctions that have struck Earth
were caused by life itself. He looks at our planet's history
in a new way, revealing an Earth that is witnessing an alarming
decline of diversity and biomass--a decline brought on by
life's own "biocidal" tendencies.”

Yours,

Paul H.
