Sorry, Gea is an engineering group in Germany..
And Sorry: was proposed by Lovelock, not Lovins..

Exactly: I'm pointing to a philisophical question that is skipped by many a die-off expert.

The Gaia theory is an interesting thought experiment, to understand the concept of bio albedo feedback, but because of it's gross oversimplification it has rather limited practical value.
