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

“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.
